Many people sell their used computers for a variety of reasons. Some sell their used computer instead of throwing them as a trash get some money from them, while others sell their used computers to buy new computers with the latest features and technology. Not only individuals sell their used computers, but also large numbers of organizations or firms sell their used computers. They do so because the computer systems may require maintenance and repairs, after some time due to the decrease in performance seen in the computers after some years. Instead of spending more money on the maintenance and repairs they sell and gain money, as there is a great demand for used computers. Such companies easily sell their used computers online through auctions or exchange for new computers with less effort in no time.
Used computers are bought by either students who do not have good savings or earnings or they are bought by educational institutions like the schools and universities. Some parents buy used computers for their children just for browsing the Internet and to play games. For this purpose, a used computer is more than sufficient than spending huge amounts on a new computer. These target segments however require used computers in a good working condition as well as for a lesser price. Most of the used computers are sold in the online market, as it attracts all sorts of buyers. There are many numbers of online classifieds or auctions or online dealers who sell used computers. Selling used computers are a better option than throwing them as trash or keeping them in a corner occupying space and collecting dust.
The first and important step is to improve the appearance of the used computer by wiping it clean free of dust and dirt. Any buyer would get impressed by the way the computer looks, looks make the first impression. The selling price of a clean used computer is always better than the one, which is full of dirt and dust.
All the software manual, operating system and other supporting discs that came with the computer should be in tact. This will add more value, when selling the used computer and also will make the buyer consider the person who is selling the used computer as a trusted seller.
The most important thing to do before selling a used computer is to erase all the personal details or information from the hard disk or drive. Instead of just putting them in the trash folder it is very important to purge all the personal data from the computer’s memory, even invisible backup files can cause danger. A tech savvy person’s help can be got if the seller does not know how to do it. If not done it may lead to accessing the bank accounts, or emails by any unknown person leading to identity theft. For that when there is a remedy. Unused scanners, printers can also be bundled with the sale of the used computer. A buyer may sometime value it. The benefits or features of the computer can be highlighted for better sales.

Creating a Wireless Desktop
We live in an age of technology and as such we are always looking for ways to make life easier or ways to make things look better. In the home or office (or even the home office) making things look better involves getting rid of clutter. This is where the wireless desktop comes into play. No wires means less clutter and because when using Bluetooth wireless devices line of sight is not needed, you can use your desk space to its optimum with no worries.
There is more to the wireless desktop than you might think as well. You will all be aware that you can get a wireless keyboard and mouse. But wireless technology and Bluetooth in particular stretches much further than that. Your mobile phone if a recent one will probably have Bluetooth technology built into it. This means that you can easily connect it to your PC. Companies such as Logitech offer software that really gets your mobile phone and your PC working together. Synchronization is just one aspect of this, but how about being able to type an SMS text message on your keyboard and send it without having to touch your phone. This is all possible with the power of Bluetooth. Communication with your mobile phone is not the only method of contact with Bluetooth. You can also get Bluetooth headsets that work with Microsoft Messenger so you can add an easy chat functionality to your desktop. As new products come on the market Bluetooth becomes more and more popular. Peripheral devices such as Printers and Scanners can now be found.
The Wireless Keyboard and Mouse
This is the first device that you will probably buy for your wireless desktop. This is the basic starting point and probably the most effective. The keyboard and mouse wires cannot be hidden away from sight as they have to be straight in front of you. plus limiting the mouse wire can mean limiting the mouse movement as well. So A wireless keyboard and mouse will give you a better looking desktop as well as freedom to move your keyboard where you want it. You can have it on your lap or anywhere else in range. Having a wireless mouse will also help in gaming. Most wireless mice are just as responsive as corded ones and your wire wont snag at that vital moment when online gaming.
Wireless Printers
While printers are not being produced as wireless as yet. The idea is very much being worked on. Currently what you can by for your USB connected printers is a two small connecters that plug into your printer and USB port which connect together like a wireless network. Its almost a wireless USB connection if you like. I doubt that is how it will be described though. The advantages of the wireless printer as well as the lack of wires behind your PC is the range can be increased as well as you being able to place your printer in a place where a USB cable would be unsuitable to travel. A second advantage would be that connecting your printer to a wireless network for sharing will be much easier.
Wireless Networking
I think the biggest advantage of wireless technology has to be Wireless Networking. While Bluetooth technology is does not have the range in which to be affective at networking computers together. RF technology is still used however and is very easy to setup. For a simple network (peer to peer) on two computers all you need is two wireless networking cards setup to the same channel. More complex networks can also be setup using a server and workstations. Anything you can do with a wired network you can do with wireless technology.
While we keep saying that the main advantage of wireless technology is that you don't have wires lying around everywhere, this is more true than ever when we are talking about wireless networking. When your computers are likely to be located in different room, the last thing you want is for wires to be laid around your home or office being an eyesore. Plus should you wish to move your computer at anytime, you don't have to re-route the wires connecting your network together.
Security on Wireless networks is set by adding a name for your network which all computers on that network must be assigned to connect to, plus then you can add a password to keep unwanted intruders out from your files. Software firewalls are also recommended on wireless connections (as well as wired) just for added security against unwanted virus' or Adware/Spyware.
Wireless Headphones / Microphone
Wireless headphones are readily available from many manufacturers. These are really one of the most practical uses of wireless technology behind the networking. Wireless headphones allow you to freely listen to your music, game or whatever noise your PC is making anywhere in your room without the restriction of wires. Even if your wires are long enough they will still be a little dangerous stretched across the room. And we all know you like to dance around your room listening to your favourite tracks. A set of wireless headphones could save you a few quid on broken items that your headphone wires have snagged on and brought crashing down to the floor :).
Wireless Speakers
Wireless speakers are poking out of the woodwork and those of you that have a 5.1 or above sound system will just how many wires are involved in that setup. Not only do you have connection to the computer but each speaker is connected to the sub / power box and and you also have the volume control to deal with. At time of writing this the US seem to have a decent supply of wireless speakers where as only a few can be found in the UK. I am very sure that wireless speakers will become a lot more popular in the UK over the next couple of months. Wireless speakers will remove loads of wires from the back of your computer. Using a 5.1 wireless system will allow you to place your speakers in the perfect position without any restrictions or ugly wires running along your walls or floor.

The History of Canon - From an Optical Lab to a Multimedia Giant!
Canon, according to the dictionary means is a general law, rule, principle or criterion; church decree or law; member of cathedral chapter; body of writings accepted as genuine.
Now what I am talking about is a company that manufactures user-friendly products! Canon the camera making company that now gives varied other products and services to the world such as printers, inks and fax machines and copiers!
Canon’s Roots
Canon’s roots were laid in 1933 with very few employees as a precision optical instruments lab. The Laboratory was founded in 1933 in a third-floor apartment of the Takekawaya Building in Roppongi, Azabu Ward, Tokyo. Its objective was to produce high-grade cameras.
A young man named Goro Yoshida, a passionate camera-lover; and his brother-in-law, Saburo Uchida, set up the Laboratory jointly. Their aim was to make cameras that could compete with the German models that were considered the most advanced of the day.
They started by analyzing existing cameras, which were difficult to obtain. Systematically, they studied each camera's internal workings, examined mechanisms, drew up design diagrams and procured parts. Takeshi Mitarai, a close friend of Uchida provided the funds required for the research. Mitarai later became president of the company and built its foundation.
It then went on to become a renowned camera making company. When it grew and decided to diversify its business plans it had to shed its image of a company that manufactured only cameras, therefore the top brass of the company decided to take on the name Canon Inc in 1969. The year1969 was also the year that canon forayed into business machines and eventually into the printing business.
Product Chronology
To go through a brief chronology of Canon’s printing and copying history - Canon successfully developed the laser beam printer in 1975. In 1982, the PC-10 and PC-20, the world's first personal copying machines with replaceable cartridges, were introduced. Canon, in collaboration with IBM Japan, Ltd., developed the world’s first notebook PC with an installed printer in 1993.
Bubble Jet Discovery
One of canon’s most interesting discoveries in the field of printing technology was the bubble jet printing technology. Researchers while working on the inkjet printing technology hit upon the discovery when a hot solder gun accidentally touched the tip of an ink-filled needle due to which ink sprayed out! Therefore, the researchers concluded that heat instead of pressure could be used to eject the ink on the media.
The development of this technology gave the world it’s first bubblejet printer in 1981.
Laser Beam Printing
Another important technology in the field of printing by Canon was the development of laser beam printers (LBP). It started research on laser as a means of writing as early as 1962. However it was unable to develop a practical laser source and hence could not acquire the patents it had applied for due to which the research and development was suspended.
In the 1970s when lasers came into practical application fields Canon resumed its research on laser beam printers and developed the LBP’s of today combining their electro photographic technologies with laser technology.
The development of lasers imprinting also gave birth to a number of high-speed copy machines by Canon such as The NP-8500, the world's first retention-type copying machine in 1978.
The NP-8500 SUPER, an ultrahigh speed-copying machine capable of producing 135 copies per minute 1981; and the PC-10 and PC-20, the world's first personal copying machines with replaceable cartridges were introduced by Canon in 1982.
In 1984 Canon gave the world its LBP-8/CX, the smallest and lightest laser beam printer.
Today Canon develops technology that couples direct printing options from Cell phones equipped with a digital camera, hence integrating printing technology with photography! One such latest technology is the direct wireless printing from a camera! The printing is achieved using infrared and Bluetooth communication technology embedded in the cell phones or PCs. Being wireless no cables are required, and the image quality parallels that of printouts from PCs using memory cards.
One important feature Canon uses to achieve real true to life image quality on paper is:
Color reproduction: The color range of digital cameras (YCC) is much wider, making it possible to capture a vast amount of color information when shooting. To achieve similar quality Canon added red ink and green ink, which offers high brightness and chromaticity, to the six existing inks in their inkjet printers, raising the saturation of the red and green output range by 1.6 times and 1.2 times respectively. The result is photo image output with improved depth and translucence, and color reproduction comparable to that of prints from photo film.

Getting Started With Your New Printer
If you have recently bought yourself a new printer, follow the directions in the manual for setting up cables. Put the installation CD into the CD drive and follow the set up instructions.
If you are using Windows 95/98, select Start Menu, then select Printers. Now select Add Printer, select Local Printer. Choose your printer (If your printer is not listed, choose the one closest to yours and select OK).
For the Mac, select go to server, (or chooser) and then select printer. Then choose your printer. (If your printer is not listed, then select the closest one.) Then select install.
If you are using Windows XP, then the PC will prompt you for the drivers and install the relevant one from the CD itself (if the appropriate driver is not in the database already).
If you have any problems printing, first check your cable connections. If you get repeated error messages, then reboot your computer and redo the steps above.
If you would like to upgrade the driver of your currently installed printed, then follow the steps given in the next sub-topic.
Installing Printer Drivers
A printer driver is a piece of software that allows the computer to communicate with the printer. Without this software, the printer would be hopelessly lost since it does not speak the same language! Printer manufacturers often update the drivers and these they can be easily downloaded form the company’s website for free. It is a good idea to keep a check on your printer driver version and upgrade if it is too far out of date.
Here is how you can check your print driver version number:
Windows XP
1. Click the Windows Start button, choose Control Panel, and then choose ‘Printers and Faxes.’
2. Right-click your default printer and choose Properties. (Your default printer will have a checkmark within a black circle above the printer icon.)
3. Click the General tab, click the ‘Print Test Page’ button, and then click OK to print the test page.
Windows 95/98
1. Click the Windows Start button, choose Settings, and then Printers.
2. Right-click your default printer and choose Properties. (Your default printer will have a checkmark within a black circle above the printer icon.)
3. Click the General tab, click the ‘Print Test Page’ button, and then click OK to print the test page.
Look on the test page for Driver Version.
All major printer manufactures have web sites that allow you to freely download their printer drivers. To do so, you will need your printer’s manufacturer and model number. When you go to the web site, look for words such as ‘Downloads’, ‘Drivers’, ‘Software’, or ‘Support’ and shortlist your model.
Given below are the website URLs for the popular brands:

Troubleshooting Printer Problems
In this section, you’ll find some of the more common problems that cause 45 percent of the help centre phone calls.
If nothing has occurred since the last time you used your printer, chances are the problem is quite straightforward. As obvious as it sounds, check to ensure that the printer is turned on. It is quite possible that somebody might have turned it off while you were away from your desk or computer. Make sure the printed is connected properly and there is power to the printer. All printers have some kind of LED that lets you know if it is powered up.
If the printer is turned on but has some flashing lights, then check with your owner’s manual to see what the lights mean. Most of these indicators will be related either to paper, ink, or toner.
Make sure there is enough paper in the printer. Refill the paper tray if it’s empty. Make sure you ‘fan’ the paper stack before putting it in the printer. When the paper stack is cut and packed at the factory, it sometimes causes the pages to stick together. Fanning the paper simply involves flipping through the paper stack with your thumb. This ruffling separates the paper, thereby reducing paper jams.
If the paper is stacked well, then check for a mis-feed or paper jam. Remove the paper stack and check the feed area for jammed paper. You may have to open several panels to make a thorough examination. Even a small piece of paper stuck inside the printer can cause problems. You might have to use tweezers to remove small pieces. Be careful of any contact of the tweezers with printer parts to avoid any damage.
If everything listed above is in place, then check the wire that connects the printer to the computer. You may be using a parallel or a USB connection. Make sure the cable is connected properly. Turn the equipment off and remove and re-insert the connection on both the printer and the computer to ensure a solid connection. If you are at work and your printer is connected to what appears to be a telephone wire, then you should call your resident network expert.
If the printer is functioning but only seems to print illegible garbage, then that is a good indication of a printer driver problem. Try re-booting the computer and turning the printer off and on before making any changes to the driver. If after re-booting you still have the problem, it's probably time to replace the printer driver. You can download the driver from the website URLs listed earlier in this articles. Follow the instructions given by the manufacturer to install your driver.
Scanner can also sometimes interfere with printers. Try re-installing the software for both but install the printer driver first, and the scanner driver afterwards.
If nothing listed above results in a solution, then perhaps it might be time to call the printer manufacturer. Make sure that you are near the printer when you call and have all your warranty information available at hand.
If you are using Windows 95/98, select Start Menu, then select Printers. Now select Add Printer, select Local Printer. Choose your printer (If your printer is not listed, choose the one closest to yours and select OK).
For the Mac, select go to server, (or chooser) and then select printer. Then choose your printer. (If your printer is not listed, then select the closest one.) Then select install.

Troubleshooting Printer Problems
In this section, you’ll find some of the more common problems that cause 45 percent of the help centre phone calls.
If nothing has occurred since the last time you used your printer, chances are the problem is quite straightforward. As obvious as it sounds, check to ensure that the printer is turned on. It is quite possible that somebody might have turned it off while you were away from your desk or computer. Make sure the printed is connected properly and there is power to the printer. All printers have some kind of LED that lets you know if it is powered up.
If the printer is turned on but has some flashing lights, then check with your owner’s manual to see what the lights mean. Most of these indicators will be related either to paper, ink, or toner.
Make sure there is enough paper in the printer. Refill the paper tray if it’s empty. Make sure you ‘fan’ the paper stack before putting it in the printer. When the paper stack is cut and packed at the factory, it sometimes causes the pages to stick together. Fanning the paper simply involves flipping through the paper stack with your thumb. This ruffling separates the paper, thereby reducing paper jams.
If the paper is stacked well, then check for a mis-feed or paper jam. Remove the paper stack and check the feed area for jammed paper. You may have to open several panels to make a thorough examination. Even a small piece of paper stuck inside the printer can cause problems. You might have to use tweezers to remove small pieces. Be careful of any contact of the tweezers with printer parts to avoid any damage.
If everything listed above is in place, then check the wire that connects the printer to the computer. You may be using a parallel or a USB connection. Make sure the cable is connected properly. Turn the equipment off and remove and re-insert the connection on both the printer and the computer to ensure a solid connection. If you are at work and your printer is connected to what appears to be a telephone wire, then you should call your resident network expert.
If the printer is functioning but only seems to print illegible garbage, then that is a good indication of a printer driver problem. Try re-booting the computer and turning the printer off and on before making any changes to the driver. If after re-booting you still have the problem, it's probably time to replace the printer driver. You can download the driver from the website URLs listed earlier in this articles. Follow the instructions given by the manufacturer to install your driver.
Scanner can also sometimes interfere with printers. Try re-installing the software for both but install the printer driver first, and the scanner driver afterwards.
If nothing listed above results in a solution, then perhaps it might be time to call the printer manufacturer. Make sure that you are near the printer when you call and have all your warranty information available at hand.

Five Myths about Compatible Toner Cartridges
Many people have different views and ideas about compatible toner cartridges. Other people simply know very little about compatible cartridges. As an exclusive user of compatible toner cartridges for fifteen years, I have found several things that are not true. I’d like to review five myths or misconceptions people may have about compatible laser toner cartridges. Let’s distinguish between fact and fiction.
Myth #1 Compatible Toner Cartridges are simply cheap cartridges.
It is true that a compatible toner cartridge is cheap in price. However, it is not a cheap quality toner cartridge. A compatible toner cartridge is a new toner cartridge manufactured by a third party. It is made from all new parts. It contains the exact toner required for your laser printer. Most companies give a one-year, one hundred percent money back guarantee on their compatible toner cartridges. You can normally purchase a compatible toner cartridge for about half of the cost of a new OEM toner cartridge.
Myth #2 Using a Compatible Toner Cartridge will void my printer warranty.
This is not true. In fact, congress passed a law to make it illegal for a manufacturer to force you to buy certain supplies. If allowed, this would lead to a monopoly, high prices and lack of competition. Below is a copy of the “Magnuson-Moss Warranty Improvement Act”. It’s your guarantee that your printer warranty will not be voided.
United States Code Annotated
Title 15 Commerce and Trade
Chapter 50 Consumer Product Warranties
15 Section 2302
“(c) No warrantor of a consumer product may condition his written or implied warranty of such product on the consumer's using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade or corporate name; except that the prohibition of this subsection be waived by the commission if:
1) The warrantor satisfies the Commission that the warranted product will function properly only if the article or service so identified is used in connection with the warranted product, and
2) The Commission finds that such a waiver is in the public interest.”
Myth #3 A Compatible Toner Cartridge will damage my printer.
The truth is a toner cartridge can do very little to damage a laser printer. It is possible, but highly unlikely, for a toner cartridge to leak and cause streaking on your paper. However, a simple cleaning and replacement of the toner cartridge will resolve the problem.
In my fifteen years of using compatible toner cartridges, I only had one instance where the toner cartridge did not meet my high expectations. I called the company and they sent me a new cartridge the next day. I learned from this experience that it is very important to purchase your toner cartridges from reputable toner companies. How many companies have sent you a brand new replacement product the next day without any hassles?
Myth #4 Compatible Toner Cartridges produce poor quality print.
One of my initial fears in purchasing a compatible toner cartridge was that the print quality wouldn’t be as good. When I used my first compatible toner cartridge, it produced exceptionally good quality. I thought it wouldn’t last. I was wrong. In fact, I printed more pages from that cartridge than I did from my original. After extensive research, I found that many toner cartridges are not completely filled with toner when you purchase them. I happened to have purchased a cartridge from a company that had completely filled the cartridge. Hence, I got more pages.
In fairness to the major printer companies, I want to clarify one thing. I used OEM toner cartridges for several years. I always printed the number of pages that the manufacturer advertised. There was no deception in their advertising. Some simply did not fill their toner cartridges to capacity.
Myth #5 All Compatible Toner Cartridges are the same.
The truth is all compatible toner cartridges are not created equal. This is why you must purchase your cartridges from a reliable and reputable company. These companies test their compatible toner cartridges to insure quality and quantity of print. You can visit our website to learn ten things you should know about purchasing a compatible toner cartridge online.
If you want to cut your printing budget in half and continue to get high quality print, do yourself a favor. Find a reputable online toner merchant and order your compatible toner cartridge today.

Computer Slow? Optimize It With The Right Tools
Why does it seem like every time you get a new computer it operates at lightning fast speeds for only a few months before becoming slow and laborious over its tasks? Is this just something that we have to live with or can we do something to keep our computers running at optimum speeds?
The truth is that computers do not get slower as they age, a slow computer is a sign that something is literally holding your PC back and affecting its performance. And the good news is that you can do something about it.
There are many things that can affect your computer’s performance, from low memory to a fragmented hard drive and everything in between. The things that can affect your computer’s performance are usually of your own doing. You see, each time we download a program or delete a program, we affect the way our computer operates. This change in operation can leave holes in our PCs operating procedures or may even leave behind programs that can affect our computer’s performance.
Here are just a few things that could be making your computer slow:
ท Running Background Programs – These programs are software applications that are running behind the scenes even when they are not in use. You may not even know that they are running, but they can zap precious memory and slow down your other tasks considerably. To see if you have programs running in the background, press Ctrl + Alt + Delete at the same time. The box that pops up will show you all applications that are running.
ท Full Hard Drive – If your hard drive is too full of data, it will not have enough space to perform chores. Your hard drive should have at lease 2MB to 3MB in free space.
ท Fragmented Hard Drive – When you download and delete programs, you create holes in your hard drive. These holes mean that your PC has to search for the files it needs over greater distance and not necessarily in the order that it needs them.
ท Left Over Parts – When you install and uninstall Windows programs, they leave behind parts or applications that can slow down your computer. You may even unknowingly delete a file needed for other software applications. (Note: Spyware and viruses can also slow down your PC’s performance, but for the purpose of this article we are assuming that the problem lies in application errors.)
Make Your PC Run Like New
While it’s not rocket science, making your computer lightning fast once again will take a little work from you. Sometimes, this is as easy as running your Windows System Tools program. You can find these programs by clicking “start,” “all programs,” “accessories,” and “system tools.” Here you will find several system optimizers to help you free up your disk space, defragment your PC, and detect and repair disk errors.
In addition to tools already installed on your PC, you can opt to download additional programs to optimize your computer’s performance. These optimizers can be purchased as a set with other software programs that can help you get the best out of your computer. Here are just a few of the extra optimization programs that you may want for your PC:
ท Memory Optimizer – When you are using your computer, it takes several programs and application to handle everything that you are doing. Each of these programs uses memory. When memory is short, computer response time is slow. Memory Optimizer helps to make the allotment of memory to each program more efficient. This can help you eliminate slow PC execution time, Windows hang up or crashing, loss of data and unwanted shutdowns.
ท Registry Deffrager and Optimizer – As mentioned before, a registry with holes results in slow response times as your PC searches for the data it needs. This program improves the system response time and saves memory by creating a smaller registry.
ท Windows Optimizer – We all use our computers differently. Some use their computer as a media and entertainment centerpiece while others use their PC for data storage and business purposes. Windows Optimizer allows you to tweak program settings so that they will perform in line with your needs.
Granted, a slow computer is a nuisance and it may leave you wanting to go out and purchase a new model. But before you give up on your current model, make sure that you have optimized it first. You may be surprised by how much life is still in your PC.

What type of asset labels do I need to buy for my school, office, company or college?
Asset Label Types
We have split asset labels into different categories and will explain their strengths and suitability and their applications.
1) Permanent frangible vinyl asset labels
2) Silver Voiding asset labels
1) Permanent Frangible Vinyl Asset Label
This label is suitable for most applications. These labels are much higher quality asset labels than the paper version and are more common in the field. The label material will conform to the majority of surfaces and forms a high-strength bond. This material has excellent initial grab and quite often (after initial application) will provide a good adhesion to many surfaces (when clean). The maximum strength of this label is attained within a 4 hour + period where the glue on the label hardens and makes the label impossible to remove in one piece
This is good for marking workstations, casings, monitors and smaller items. The grain on the computer plastics can be tricky to adhere to with certain asset labels, but the vinyl labels are very effective for this application. The material is also suited to varnished and smooth surfaces. These labels can be personalized with Code 39 barcodes, serial numbers and often with the logo printed too. Some companies offer further protection with a hologram label included to prevent counterfeiting. The vinyl labels are usually supplied on reels and most companies offer a turnaround within 33 to 5 days however some companies offer 24hr / next day service.
These are great for Hospitals, Schools, IT Department & Offices as when the adhesive sets it becomes very strong prevents people or children removing the labels in one piece.
This vinyl asset label material is suitable in many different applications such as:-
PC & IT Equipment, Monitors and LCD displays, Laptop Computers, Keyboards, Mice, Mobile Equipment including PDA's, Networking Equipment, Fileservers, Hard Drives, Printed Circuit Boards, Painted Metal Surfaces, Wood, Plastics, Glass, Metals, Paper Surfaces, etc.
2) Silver Voiding Asset Label
This substrate is used primarily in situations where tampering needs to be revealed. The construction of the material utilises a two stage adhesive. The label will grab very well and on any attempt of removal, will leave the words VOID on the label and on the material it is stuck to. Even if you try to replace the label by sticking it down in the same position it is still apparent that tampering has taken effect.
This material is used in many different applications such as:-
Covering Memory & Expansion covers on IT Equipment, Sealing Paper, Card & Plastic surfaces, Calibration Seals, Sealing Postage Bags, Medicine Boxes and Cartons, Electronic Enclosure Boxes, HiFi & Stereo Units, Computer Cases, Mobile Telephones, PDA's, Sealing Doors, NHS & Medical Equipment, Oscilloscopes, etc.

Getting the Most Out of Your Photo Printer – For Less!
As many photo-printer owners would know, paper and ink costs can quickly exceed the cost of the printer. These six tips will help you get the most out of your photo-printer without leaving a hole in your pocket.
Raise the Resolution: Any digital camera that is less than three years old can capture at least 1 megapixel of data with each shot. This is sufficient to print a good-quality 4 X 6-inch photo; a 2-megapixel image holds enough information to output a higher-quality print of the same dimensions. To generate an 8 X 10-inch print worth framing, you'll need a resolution of at least 3 megapixels. You're in a good position if you have a new camera as most new models offer from 4 to 8.1 megapixels.
Adjust your camera to its highest resolution when taking shots that you might want to print. Some newer cameras, depending on the manufacturer's menu setup, make it very simple to change resolution.
Save your Originals: Don not save the images you plan to print as JPEGs or in any other compressed file format. Each time you compress an image, you lose some data. Before working with an image, make sure it is unaltered and in the TIFF format.
Enhance the Image: Experiment with your image-editing program's functions such as cropping, contrast, brightness, and other controls until you're entirely satisfied with the image's composition. Remember to always save the altered file with a new name.
Plan Your Print Drafts: If you plan to make test prints that you will discard later, reduce the image size and load the printer with plain inexpensive paper. Your printer software may allow you to print multiple images on one sheet.
Use matte-finish photo cards instead of glossy photo paper when printing 4 X 6-inch images. These cards have a nice look and feel, and they cost almost half as much as full-size photo paper. Place the images that you print on 8 X 10-inch glossy photo paper behind glass for added protection from ultraviolet light, and hang them away from direct sunlight.
Save on your ink: Special photo inks can provide your printer with a more refined colour palette. Unfortunately, these come with specific models, and if such ink didn't come with your model, you may have to buy it separately and install it in place of the standard ink cartridges.
In some cases, photos printed using general-purpose cartridges look almost as good as ones printed using photo ink. Another effective trick is to print your black-and-white photos in colour mode (with standard colour cartridges). This makes the printer use all of its inks to create the tones in your picture, and the resultant prints can be as subtle and precise as pictures printed with photo inks.
Get your Cartridges in Line: Use your printer's controls to realign your cartridges--especially if you see vertical or horizontal bands, unwanted lines, gaps, or bleeding colours in your prints. Right-click the printer's entry in Control Panel's "Printers and Faxes" or "Printers" applet, click Properties, and search for a cartridge maintenance option. If aligning your cartridges does not solve the problem, clean the cartridges with a cotton swab dipped in isopropyl alcohol. Use water merely as a solvent, and clean just the cartridge itself, never the print head or the nozzle plate. Always align new cartridges.
Practice Good Housekeeping: By keeping your printer's mechanisms clean, you will ensure that the device runs at its best. An occasional blast from a can of compressed air (easily available at electronics stores) will keep dust and bits of paper from clogging the paper path and other moving parts.
Make sure that the small ink nozzles on your print heads are clear of dried ink. Leaving any inkjet idle for even a week or two leads the ink in the tiny tubes that feed the nozzles to dry. Many inkjet printers have a cleaning program in their settings that can handle partially clogged nozzles.
Unfortunately these programs use a lot of ink, so use them judiciously. If the tubes are badly blocked, then you will need the services of a professional or an inkjet cleaning kit.

Get To Know The Components Of The Keyboard
Your computer use output devices such as your Monitor to send data to the computer user.This same user must also use input devices to send data to the computer.
Even though you won't open your keyboard to make any repairs other than to unstuck a stuck key or replace a broken retainer,its a good idea to study every part of your keyboard. If you're blessed enough to have an extra keyboard, take the time to open the case and study each component in great detail.
Some of the special features of newer keyboards are that they can be Cordless and is often used with such devices as the cordless Mouse.Special keyboards may be used when the user may want have the freedom of movement. The average user will have very little use for the cordless keyboard or mouse.
The keyboard come in layouts which refer to how to keys are arranged.The Alphanumeric Key layout are the letters, numbers,and symbols.This is the most commonly used type the keyboard layout. The QWERTY Layout is the most popular Alphanumeric layout
The keyboard must have power to operate and it get this power from the motherboard.The operation of led indicators let you know the keyboard is receiving power.
Use the right rool,usually a screwdriver to open the case and study the components inside.You will not replace these components but it will boost your understanding of computers when you know every part of every device in your computer.
THE KEYBOARD CASE
Yea,I know,this is going to be exciting to discuss. While there is nothing much to discuss about the case of the keyboard,we don't want to cut corners.
You may have to help someone with their ailing keyboard so you want to be on your toes. With that in mind,let's get hyped up as we begin our keyboard case discussion.
Ready,the keyboard case is almost always plastic. I told you this would be exciting.This case holds the keycaps,the internal controller and other chips.
Keyboard LED Indicators will have a set of three LED indicators. They are used to display the current operation of the keyboard. NUM LOCK, CAPS LOCK,and SCROLL LOCK are the three standard led indications found on most keyboards.
The most popular keys such as the Enter Key and the Space Bar will get used often.These keys may be the ones that will need to be replaced.The springs or clips underneath may give in to wear and tear over time.
INSIDE THE KEYBOARD
As the CPU is the brains of your computer,the brains of your keyboard is the circuitry inside.These circuits and chips process the operation of every keystroke.
The keyboard has its own Microprocessor and ROM or Read Only Memory that the micropressor use to transfer data.
Some keyboards are programmable and uses the EEPROM or Electrically Erasable Programmable Memory, which holds data,acting like a very small hard drive.
CABLES AND CONNECTIONS
Wired keyboards will have a cable that connects to the rear of the computer through a serial connector. There are two types of keyboard connectors.The large 5-DIN connector or Deutsche Industrie Norm was used on the first systems up to the mid 1990s.
The smaller 6-DIN was made by IBM for the PS/2 and later model computers.Each pin provides a special function to transfer data to the computer.
INSTALLING THE KEYBOARD
Unless you've invested in one of those super duper special featured keyboards which will reqiure the installation of software,you simply connect the keyboard to the rear of your computer.
When the system is booted up,the new keyboard will be recognized and you're on your way.Notice the Led indicator lights to verify the keyboard is receiving power.
And that's it.The functions of the keyboard can even be replaced if you have Windows XP.Special features help you should your keyboard decide it want to quit.www.ultimatepcrepair.com/photos.html is where to see all components of your computer.
Gather as much information and data about your system now,while it is still running smoothly.Prepare for computer breakdown before it happens.
Even though you won't open your keyboard to make any repairs other than to unstuck a stuck key or replace a broken retainer,its a good idea to study every part of your keyboard. If you're blessed enough to have an extra keyboard, take the time to open the case and study each component in great detail.
Some of the special features of newer keyboards are that they can be Cordless and is often used with such devices as the cordless Mouse.Special keyboards may be used when the user may want have the freedom of movement. The average user will have very little use for the cordless keyboard or mouse.
The keyboard come in layouts which refer to how to keys are arranged.The Alphanumeric Key layout are the letters, numbers,and symbols.This is the most commonly used type the keyboard layout. The QWERTY Layout is the most popular Alphanumeric layout
The keyboard must have power to operate and it get this power from the motherboard.The operation of led indicators let you know the keyboard is receiving power.
Use the right rool,usually a screwdriver to open the case and study the components inside.You will not replace these components but it will boost your understanding of computers when you know every part of every device in your computer.
THE KEYBOARD CASE
Yea,I know,this is going to be exciting to discuss. While there is nothing much to discuss about the case of the keyboard,we don't want to cut corners.
You may have to help someone with their ailing keyboard so you want to be on your toes. With that in mind,let's get hyped up as we begin our keyboard case discussion.

Types of Computer Hardware
Computer hardware is a physical part of a computer that executes within the hardware. It is unlike computer software or data that can be frequently changed, modified or erased on a computer. Computer hardware is not frequently changed and so is stored in hardware devices such as read only memory (ROM) where it is not readily changed.
Most computer hardware is embedded and so is not visible to normal users. Below are the different types of hardware’s found in a computer.
Motherboard: It is the central or primary circuit board making up a complex electronic system such as a computer. A motherboard is also known as a main board, logic board or system board.
Central processing Unit: A CPU is the main component of a digital computer that interprets instructions and process data in computer programs.
Random Access Memory: A RAM allows the stored data to be accessed in any order. RAM is considered as the main memory of the computer where the working area is used for displaying and manipulating data.
Basic Input Output System: BIOS prepares the software programs to load, execute and control the computer.
Power Supply: Power Supply supplies electrical energy to an output load or group of loads.
Video Display Controller: It converts the logical representation of visual information into a signal that can be used as input for a display medium.
Computer Bus: It is used to transfer data or power between computer components inside a computer or between computers.
CD-ROM drive: It contains data accessible by a computer
Floppy disk: It is a data storage device
Zip Drive: It is a medium capacity removable disk storage system.
Hard Disk: It is a non-volatile data storage system that stores data on a magnetic surface layered unto hard disk platters.

Computer Consulting Business: Know about Vendor Hard Drive Replacement
Many of your computer consulting business clients will come from non-technical, business backgrounds. As a result, many will not immediately grasp why a failed hard drive cannot "simply" be replaced by a new or refurbished hard drive.
As part of managing clients expectations, it’s important to educate your clients on the steps that go into formatting a hard drive, loading the OS, configuring device drivers, loading software applications, customizing the OS and applications and restoring data.
Educate Your Client
As a computer consulting business owner, you know replacing a hard drive is not as simple as removing the shrink wrap and installing the device into the PC. But, many times, your clients don’t.
Or they just assume that all the OS files, device drivers and software applications will "magically" appear. This all may sound really basic, but taking a few minutes when discussing PC warranties with your clients to explain these issues.
How does the Vendor Handle Hard Drive Replacement?
You need to know how your preferred PC vendors handle hard drive replacement under warranty service. What kinds of labor are covered if a desktop PC or notebook hard drive needs replacement under the warranty?
Some vendors specify that the hard drive device needs to be just physically replaced and operational, and recognized by the PC hardware setup program. Under this form of warranty coverage, the technician’s job is done the moment the empty (blank) replacement hard drive is installed in your client’s PC.
The Real Cost
Unfortunately, as most PC vendors feel financial pressure to reduce their support and warranty costs, your computer consulting business clients probably will be subjected to a no-frills warranty service approach. Hard drives for desktop PCs are relatively inexpensive, around $100 to $200 at retail.
So it’s important for your clients to understand that warranty service on a hard drive replacement generally doesn’t cover the more substantial labor costs involved with restoring the hard drive and system to the pre-crash condition.
If your clients outsource this work to your computer consulting business, it easily could cost them $200 to $500 (or more) in labor to get that PC hard drive back to its pre-crash condition. Even if your clients’ internal gurus handle the work, this easily could pull these internal gurus away from their "real" jobs for a half-day or more.
The Bottom Line about the Computer Consulting Business
The expense of recovering a crashed desktop PC hard drive tends to be more concentrated on soft costs, which most times aren’t covered by the PC vendor’s warranty, therefore we see more and more reason not to recommend purchasing extended warranty coverage with entry-level desktop PCs.

Colocation Facility Cooling System Considerations
Most companies know to find a colocation facility that has good Internet service and Internet provider and carrier options. However, cooling systems are often overlooked. Most servers now are made to operate at normal office conditions, which mean that two environmental factors should be met:
If the cooling system goes down, it can cause the equipment to overheat, causing the network to go down and even damaging equipment. Colocation facility cooling systems include three areas: the facility layout, chillers, and computer room air conditioning (CRAC) units.
Facility Layout
Servers generate heat as they run. This is generally blown out the back of the server by fans; cool air is taken in through vents at the front. Server racks and rows should be laid out to manage hot air coming from the servers and conditioned air going to their intakes by designating “hot rows,” which face the server fans, and “cold rows,” which face the intakes. Designated hot and cold rows keep air circulating in the best directions to keep servers from overheating.
Facility Design
There are two kinds of building design for colocation facilities: raised floor and solid floor. Raised floor was the preferred structure when servers were towers because the mesh flooring allowed air conditioned air to blow from the bottom directly across their intakes. However, since servers are stacked in racks, cold air must reach the tops of the racks to cool machines. Solid floor facilities are a better option. The facility should take into account the following:
Chiller Systems
Chillers pipe water or water/glycol coolants through the CRAC units. Chiller systems include pumps, pipes, and the chillers themselves. The following points should be considered to make sure that the system is adequate to cool the facility:
CRAC Units
CRAC units are massive, dedicated air conditioners which manage temperature and humidity. They have many parts and are complicated – meaning failures can be common. The CRAC units should be well maintained, but the most important thing is redundancy. Redundancy is determined by the overall capacity of the CRAC units; there should be enough units that even with a failure, the facility will still be adequately cooled. As with chillers, capacity for CRAC units is determined by tons per square foot.
Verify Capacity
Capacity is determined by the ratio of tons per square foot. To determine whether a system has sufficient capacity, divide the total tonnage of the units by the square footage of the building. If there are four 30-ton CRAC units in a 4,000 square foot facility, then the CRAC capacity is .030 tons per square foot (120 tons / 4,000 square feet). The ideal ratio of tons to square feet for the CRAC system is .030 ton/square foot or higher; the ratio should not be below .025 tons/square foot. This same formula is used for chiller systems, with the same ideal ratios.
It is important to look for a colocation facility that has Internet provider options and backup power systems. Equally important is a facility with the right design, chillers, and CRAC units to cool the server room. Keeping equipment from overheating will keep networks up and makes equipment last longer. Like Internet connections, network uptime, and power backups, cooling systems signify a quality colocation facility.
- The temperature should stay between 72° F and 76° F
- The humidity should be between 45% and 60%, with 45% ideal
- Cooling units must be on continuously, so servers will not overheat (this precludes standard HVAC units).
If the cooling system goes down, it can cause the equipment to overheat, causing the network to go down and even damaging equipment. Colocation facility cooling systems include three areas: the facility layout, chillers, and computer room air conditioning (CRAC) units.

However, since servers are stacked in racks, cold air must reach the tops of the racks to cool machines. Solid floor facilities are a better option. The facility should take into account the following:
- Solid floor designs must have mesh front and rear doors for th server cabinets to allow hot air to escape.
- For raised floor designs, cold air must have enough air pressure to force air to the top of the server cabinets. Ideally, special duct work will be in place to force the airflow upward.
- For raised floors, server cabinets should not have vents in the doors that would let cool air escape.
Chiller Systems
Chillers pipe water or water/glycol coolants through the CRAC units. Chiller systems include pumps, pipes, and the chillers themselves. The following points should be considered to make sure that the system is adequate to cool the facility:
- Sufficient capacity
- Backup units for the pumps and chillers which switch over automatically
- Regular maintenance

Choosing the Right Motherboard for you
The motherboard is the heart of any computer. It is that big flat board inside the computer that everything is connected to. It performs the role directing information and connecting components. A motherboard is often overlooked when choosing components. This is a scary thought as the motherboard determines system performance as much as every other component.
Choosing the right motherboard does not have to be a problem, even though there is a lot to consider. We will start off with the larger parts and move onto the things that are less essential.
Firstly is the socket type. The socket is where the processor (CPU) connects to the motherboard. There is no compatiblility between sockets, so it has to be the right one. The socket connection needs to match the connection of the processor you have or the one you intend to buy for the computer.
Most older Intel Pentium 4s utilize socket 478. Newer ones use socket 775. AMD chips utilised socket A for a long time, but now the AMD Athlon 64 series and Semprons use socket 939. Just check with someone as to what yours or your intended one will have.
Your choice of chip will have a lot to do with your needs, but choosing one with an up to date socket type will ensure slightly longer motherboard life as you can upgrade the chip for a while.
DDR is the RAM of choice for most systems, but some newer systems, which includes all Pentiums with socket 775 use DDR2. These two kinds are not interchangable and have a different number of pins. Both DDR and DDR2 come in different speed ratings measured in MHz. DDR has a usual 400MHz denoted as DDR400 or PC3200, while DDR2 can go a little higher and comes in slightly faster speeds. Just make it match what the board needs.
A motherboard must be chosen carefully, to both match all the other components and fit in the case you choose. A little bit of research before you buy will save a lot of hassle later on.

CD/DVD Burners
Some people think with the standardization of DVD burners on new computer systems, CD burners have become obsolete. Most people with CD burners will tend to disagree, as do I.
Before going out and purchasing a CD Burner or DVD Burner the requirements of the individual need to be determined allowing the best choice to be selected.
A DVD Burner is used for copying or duplicating a DVD disc or to burn video files into DVD Format so they can be played on a home DVD player. DVD discs allow Gigabytes of Data to be burned to the disc, in some cases a whole hard drive of data, making a tempting choice to use as a data back-up tool.
We need to remember that to be able to read the DVD, a DVD ROM is required. If you are in an office environment and need to use the disc on multiple computers then this may cause an issue as most computers in an office don’t come installed with a DVD-ROM – if they do then it’s a waste of money on the IT departments part.
Although CD Burners are somewhat slower than today’s DVD burners they do have more pros than con’s when comparing to a DVD Burner for data back-ups. Blank media Discs for CD Burners are either 650MB or 700MB in size, yes a lot smaller than that of a DVD disc.
CD-R discs can either hold data or audio and can be read in almost any CD-ROM and if the CD-R is made into an audio disc then its possible to read the disc in a Hi-Fi or a car CD Player – you will need to make sure the drive has the ability to read CD-R media, most newer models of CD-Players are compatible to read CD-R media.
DVD burners only have the advantage of size of CD burners. Now that DVD burners are becoming more and more popular, the prices of CD burners and media are dropping dramatically making them a very cost effective purchase.

Securing Your Wireless Computer
Wireless Internet connections aren't just convenient for you-they also may be convenient for hackers. Fortunately, it isn't difficult to protect yourself.
Wireless systems can be particularly vulnerable to digital intruders, possibly putting sensitive or private data at risk. However, you can protect yourself by using WEP or WPA encryption, which require users to enter a password before they are allowed to access your wireless network.
These encryption methods are described in easy-to-understand language in a new book called "Geeks On Call Wireless Networking: 5-Minute Fixes" (Wiley, $14.95). The book also offers expert advice and step-by-step explanations of topics ranging from configuring a wireless router to troubleshooting a slow connection.
Here are some additional tips from the book that can help you protect your wireless network.
• Reduce the range of your network. Doing so can keep nosy neighbors from intruding on your connection. Move your wireless router into the center of your home and decrease its power settings.
• Pick a new password. Most routers have a default password of "admin." Be sure to change it.
• Disable SSID broadcasting. Most wireless routers broadcast the names of user networks (SSIDs) so that other users can log on. This could be a security risk.
• Use encryption to protect credit card information you send wirelessly over the Web. Also, only use your card on a Web site that has SSL encryption (look for a padlock in the corner of the site).
• Disable your wireless card when not in use. There's no better way to secure your computer.
• Use a firewall, which is a program that shields your computer from Internet criminals.
• Don't use shared files. Remove all important documents from your Shared Files folder before accessing a public network.
• If you use a wireless laptop, disable the feature that attempts to connect your laptop to any available wireless network. For most Windows-based laptops, double-click the wireless icon in the lower right corner of Windows. Then click "Properties." Click the "Wireless Network" tab. Next, click the "Advanced" button. Uncheck the "Automatically Connect to Non-Preferred Networks" option. Finally, click "Close."

Thermal paper is ultimately cheaper.
Thermal paper is cleaner than your standard ink, produces a crisper resolution, and is ultimately cheaper. Though thermal paper used to be considerably more expensive, the price has come down in recent years, thanks in part to better technology that allows its manufacturers to produce it at a more reasonable cost. Moreover, a thermal paper roll is quieter than bond paper, which is an added bonus for any shopper at the end of a long day.
Appleton uses ideas that make a difference to create product solutions through its development and use of coating formulations and applications, encapsulation technology, and specialized and secure print services. The Company produces carbonless, thermal, security, and performance packaging products. Appleton is headquartered in Appleton, Wisconsin, and has manufacturing operations in Wisconsin, Massachusetts, Ohio, Pennsylvania and the United Kingdom, employs approximately 3,400 people, and is 100 percent employee owned.
When it comes to buying thermal paper, you could possibly be facing high prices at the store. This shouldn't stop you from using this superior product. I've found that it's far easier and more affordable to simply buy your receipt paper rolls and other cash register supplies from online vendors.
The type of thermal paper you choose depends largely on the specifics of your business. The width, length, and grade of thermal paper varies widely depending on the manufacturer and the type of machine the paper is used for. Many online wholesalers, however, can customize your order so that you get the product you need to keep accurate records of all your transactions.
Our test results prove with certainty that LightSafe 300 stays white longer than any direct thermal label paper on the market," Cove said. "This breakthrough ensures the long-term durability of direct thermal media. Now, end users in warehouse and supply chain applications can convert to direct thermal for their long-term label needs and take full advantage of its technological benefits and corresponding better overall value.
Thermal paper is paper that is impregnated with a chemical that changes color when exposed to heat. It is used in thermal printers and particularly in cheap, lightweight devices such as adding machines, cash registers, and credit card terminals.
