Make sure that your computer table is quiet clean, do not litter the place with all your food items or tea and coffee, as once if they fall on the monitor, it is completely spoiled and you will have you spend tremendous amount for buying a new monitor. Don't press your monitor with fingers. Many people do not know how to clean the monitor of the computer. Never treat your monitor as a piece of empty box.

Even though many companies have come up with many liquid products for cleaning monitors, they are not so effective and some may perhaps ruin your monitor. Generally monitors are of two types, they are cathode ray tube (CRT) and Liquid crystal display (LCD), so depending upon the type of the monitor you can clean it. For cleaning the dust of a CRT monitor always use a cloth which is extremely soft or use an anti static cloth. Then spray a small amount of fluid liquid in the cloth and then gently rub the monitor in one direction throughout the monitor. After you're done doing that then use a dry cloth to dry the monitor.

Cleaning a LCD monitor

The process of cleaning a LCD monitor is little different as the LCD monitor is little fragile. To start cleaning a LCD monitor take a soft cloth and first gently wipe the dust from the computer and then put cider vinegar or alcohol on the cloth and water as well upon the cloth and then rub the cloth tenderly on the LCD in the same direction for the entire LCD monitor. And finally use the other dry and soft cloth to dry the monitor.

Whether if you are cleaning a LCD monitor or CRT monitor, the first thing which you have to do is switch off your computers and unplug it. Don't use a liquid which is very soapy. Always use a lint free cloth. If you do not have a soft or lint free cloth, then you can even clean the monitor with cotton swabs or foam swabs. All the above were few important points and tips for cleaning a monitor.

Error code 22: Configuration error

These error codes are typically associated with improper configuration for the computer or the printer. Make sure the I/O cable isn't damaged. Check if the I/O port on the printer is damaged or not.
