Perform maintenance peripherals

Computer peripherals is a supporting equipment from a PC.

In general peripherals can include a keyboard, mouse, monitor, and printer.

Peripherals, in general experiencing problems caused by dust, water spray, and dirt.

To clean can be used for equipment and materials as simple as:


Melakukan perbaikan periferal HOME

• Kain kering atau tisu

• Brush

• Mini vacuum cleaner

Brush is the equipment used to clean the dustor feces left behind in the peripherals.

Mini vacuum cleaner with almost the same brush used to remove dust. But the vacuum cleaner is easier to clean and more. At the end of a vacuum cleaner equipped with a mini brush with a variety of sizes, are intended to adjust the limited wide-angle corner at the peripherals.

Dry tissue or cloth used to clean the dirt that may be due to liquid softdrink, ink or rain water that is still fresh or not dry out.



HOME

Dry tissue or cloth used to clean the dirt that may be due to liquid softdrink, ink or rain water that is still fresh or not dry out.

Tissue or cloth to dry the liquid sewage is very dangerous if not cleaned immediately because this type of dirt can bring cash so that the relationship can lead to short or damage to the peripherals.

Tissue can also be used to expedite the flow of ink in the printer cartridge injek, because that is easy to absorb liquid.

While the cleaning fluid used to clean the stains or dirt that has been kiln such as sprinkling of printer ink. Used in the screen, casing, body



Dust is one of the types of dirt that are on the computer peripherals.

Dust can enter into the components outside of or arising out of the fan suck air.

Dust-dust, this will be a function of the peripherals, because the dust can impede electrical flow.

Liquid ink or dirt that came from a drink is also very common and cause problems in the computer peripherals.

Following types of issues that arise in the computer peripherals:



Dust and dirt can enter into the keyboard between the keys on the keyboard.

Dust and dirt will accumulate and solidify into a lot of that will disrupt the comfort in the button pressing the button or the keyboard will be hard.

In addition to compact dust and dirt, the dirt type of liquid is also very common.

Drink is the cause of the spill that occurred that often create traffic jams the keyboard, such as terpencet hold the key, and can also occur Hubung which may cause short-keyboard can not be used again, and the most severe cause port PS / 2 on the motherboard



Dust on the monitor screen will dim and if the dust patch is already on the screen is cleared and does not scratch the screen can be properly monitored.

In addition to on the screen, dust can also cover fentilasi air on the monitor that will cause excessive heat on the monitor.

For liquid sewage into the monitor can cause damage to a monitor.



Dust on the fan is very often found if the computer peripherals are located in the open space or a lot of dust, because dust is tersedot by akan fan casing and fan the other peripherals.

This will prevent dust lap fan if you have stick to the axis of the fan.



PrinterComputer peripherals is a printer that is prone to both liquid is exposed to dirt and dust.

To result in dust will roller paper to be obstructed player this is the case if dust accumulate too many already.

While for the sewage liquid ink caused by the spill. Besides will draggle ink printers can pollute or head cartridge.

Please note that cartridge is a component that is very vulnerable, so that the most serious trouble is dead cartridge is often the case that



Mouse

Mouse peripherals are most vulnerable to dust, especially that still use the mouse ball.

Touch directly with the mouse pad (mouse pad) where the base is a source of dust.

If the dust has been attached to the mouse, the ball movement is not normal, it can be seen from the movement of the cursor jump - jump or are very slow, this will make the mouse harder directed.



Doing Care Peripheral

To make cleaning components peripherals on the way or passing through certain procedures.

Procedures that must be taken disesuakan with the type of peripherals and dirt that is on the peripherals.

Next steps cleaning components peripherals:



Keyboard

Keyboard must be cleared to open in the first, on the inside on the keyboard must be carefully cleared in the very vulnerable due to the scratches that can cause the path to become dropouts.

To clean the keys penghantar items on the charcoal or penghantarnya.

For the connector cable is also examined, especially because the cable is very small and the keyboard cable is usually very easy to himpit both tables and other objects.


Mouse

Procedure to clean the dust from the mouse:

Use a cloth and cleaning fluid or feces of dust attached to the ball and the axis on the mouse.

Cleaning liquids used if dirt or dust attached to the ball bearing or stubborn.



Monitor cleaning procedure:

Use a small brush or the tip of the vacum cleaner with a small brush to clean the dust.To clean the monitor of the liquid stick to the dirt on the screen, use liquid detergent and then dilap with dry cloth. Especially at the corner of the screen.

Monitor



Printer

Problems with the printer ink is often caused by the spill and prevent the dust on the paper roller player.

To stick to the ink in the printer body or case with enough clean damp cloth.

Whereas for the ink overflow or spill at the need to be used in tissue y ang soft and easily seep fluid.

On the print head will need to carefully in tissue mengusapkan, never touch the head with the hands because it will create corrosion on the printer head.



Printer maintenance procedures:

Use a damp cloth to clean the printer. Do not use a flammable liquid such as alcohol, benzene or thinner. When flammable liquids are related to the electrical components in the printer may result in fire or short. Always disconnect the printer from the stop at the time of the contact printer cleaned.

Do not put the printer in a place that is not stable or easily affected by vibration or shock. The printer can be damaged and fall.

Do not put the printer in a humid or dusty, which is exposed to direct sun or near a heat source or fire.



Corrosion in the computer peripherals

Corrosion on components computer peripherals rarely happens, usually only happens on the printer.

Due to the computer's peripherals are generally made of anti-corrosion material.

So for the type of corrosion in the computer peripherals was: corrosion on the metal, usually located on the mat or plug head caused by left hand sweating.

Corrosion will result in reduced power hantar connector so that it can disrupt the peripherals.
