Scanner Cleaning

2009-03-28T12:36:00.000-07:00

Why? Flatbed scanners commonly become dirty with dust, fingerprints, and hair. When a scanner is dirty, the images may have distortions.

Procedure: Clean a flatbed scanner's surface by spraying a window cleaner onto a paper towel or cotton cloth and wipe the glass until clean. As mentioned earlier, never spray a liquid directly onto the component.

To clean the outside of the scanner, the same towel or cotton cloth can be used.

Printer Cleaning

2009-03-27T12:22:00.000-07:00

Why? Cleaning the outside of a printer can help keep the printer's appearance looking good; and in the case of a printer that is used by many different people, keep the printer clean of germs.

Procedure: First, make sure to turn off the printer before cleaning it. Dampen a cloth with water or rubbing alcohol and wipe the case and each of the buttons or knobs on the printer. As mentioned earlier, never spray any liquid directly onto the printer.

Why? With some printers it may be necessary to clean the inside of the printer to help keep the printer running smoothly.

Procedure: Because of numerous types of printers, different steps in cleaning printers, and printer manufacturer policies on cleaning the inside of the printer, we recommend you obtain the printer cleaning steps from your printer manufacturer.

Mouse cleaning

2009-03-25T11:39:00.000-07:00

Why? A dirty optical-mechanical mouse (mouse with a ball) can cause the mouse to be difficult to move as well as cause strange mouse movement.

Procedure: To clean the rollers of an optical-mechanical mouse, you must first remove the bottom cover of the mouse. To do this, examine the bottom of the mouse to see which direction the mouse cover should be rotated. As you can see in the below illustration, the mouse cover must be moved counter clockwise. Place two fingers on the mouse cover and push the direction of the arrows.

Once the cover has rotated about an inch, rotate the mouse into its normal position, covering the bottom of the mouse with one hand and the bottom should fall off including the mouse ball. If this does not occur, attempt to shake the mouse gently.

Once the bottom cover and the ball are removed, you should be able to see three rollers located within the mouse. Use a cotton swab, your finger, and/or fingernail and move in a horizontal direction of the rollers. Usually, there will be a small line of hair and or dirt in the middle of the roller, remove this dirt and/or hair as much as possible.

Once you have removed as much dirt and hair as possible, place the ball back within the mouse and place the cover back on.

If the mouse still appears to be having the same issue, repeat the above process; if after several attempts the mouse is still having the same issues, it's likely that your mouse has other hardware issues and we recommend that it be replaced.
Note: Cleaning your mouse pad with a damp cloth can also help improve a computer's mouse movement.

Why? To help keep a mouse clean and germ free it can be helpful to clean the mouse.

Procedure: Use a cloth moistened with rubbing alcohol or warm water and rub the surface of the mouse and each of its buttons.

Motherboard cleaning

2009-03-24T13:54:00.000-07:00

why? Dust and especially particles of cigarette smoke can build up and corrode circuitry causing various problems such as computer lockups

Note:- When inside the computer take the necessary ESD precautions and try to avoid unplugging any cables or other connections.

Procedure:- Our recommendation when cleaning the motherboard from dust, dirt, or hair is to use compressed air. When using compressed air, hold it in the up-right position; otherwise, it is possible chemicals may come out of the container that could damage or corrode the Motherboard or other component within the computer. Also, ensure when using compressed air that you always blow the dust or dirt away from the motherboard, or out of the case.

Another good alternative to compressed air is to use a portable battery powered vacuum that can effectively remove the dust, dirt, and hair from the motherboard completely and prevent it from getting trapped within the case. However, do not use a standard electricity powered vacuum as it can cause a lot of static electricity that can damage the computer. When using the vacuum it is vital that you stay a couple inches away from the motherboard and all other components to help prevent contact as well as to help prevent anything from being sucked into the vacuum. Ensure that you do not remove any small components with the vacuum such as jumpers.

Tip:-When cleaning the inside of the case also look at any fans and/or heat sinks. Dust, dirt, and hair collects around these components the most.

Monitor cleaning

2009-03-13T22:22:00.000-07:00

Note: This section is for computer monitors if you have a LCD or flat-panel see our LCD cleaning section

Why? Dirt, dust, and fingerprints can cause the computer screen to be difficult to read.

Procedure: The glass monitor screen can be cleaned with ordinary household glass cleaner*. Be sure to remove power from the monitor and spray the cleaner onto a lint free-cloth so the fluid doesn't leak into the electrical components inside the monitor. Vacuum off any dust that has settled on top of the monitor, and make sure no books or papers have been placed on the air vents. Obstructed monitor vents can cause the monitor to overheat or even catch on fire.

Premoistened Monitor Cleaning

Rock LCD/Laptop Monito

LCD-TFT Screen Monitor

Warning: We suggest using a cloth dampened with water when cleaning monitor on a screen that is not made of glass or has any type of anti-glare protection on the screen. Using ordinary household glass cleaner on special screens, especially cleaners with ammonia can remove anti-glare protection and/or other special surfaces

LCD cleaning

2009-02-09T10:50:00.000-08:00

Why? Dirt, dust, and finger prints can cause the computer screen to be difficult to read.

Procedure: Unlike a computer monitor, the LCD / flat-panel display is not made of glass, therefore requires special cleaning procedures.

When cleaning the LCD screen it is important to remember to not spray any liquids onto the LCD directly; do not use a paper towel as it may cause the LCD to become scratched.

To clean the LCD screen we recommend that you use a soft cotton cloth; if a dry cloth does not completely clean the screen, you can apply rubbing alcohol to the cloth and wipe the screen with the damp cloth. Rubbing alcohol is actually used to clean the LCD before it leaves the factory.

Keyboard cleaning

2009-02-09T10:48:00.000-08:00

If you're trying to clean a laptop keyboard see document CH000780 for additional help and information. All of the below information applies to standard desktop computer keyboards.

Why? Dirt, dust and hair can build up causing the keyboard to not function properly.

Procedure: Many people clean the keyboard by turning it upside down and shaking. A more effective method is to use compressed air. Compressed air is pressurized air contained in a can with a very long nozzle. Simply aim the air between the keys and blow away all of the dust and debris that has gathered there. A vacuum cleaner can also be used, but make sure the keyboard doesn't have loose "pop off" keys that could possibly be sucked up by the vacuum.

Why? If the keyboard has anything spilt into it (ie: pop, Pepsi, Coke, beer, wine, coffee, milk, etc.), not taking the proper steps can cause the keyboard to be destroyed.

Procedure: Below are a few recommendations to help prevent a keyboard from becoming bad once a substance has been spilt within it.

If anything is spilt onto the keyboard turn the computer off immediately. Once the computer is turned off, quickly flip the keyboard over helping to prevent the substance from penetrating circuits. While the keyboard is upside down, shake the keyboard over a surface you do not mind getting wet or that can be cleaned up later. While still upside down, use a cloth to help clean out what can be reached. After you you have cleaned the keyboard to the best of your ability leave the keyboard upside down for at least one night allowing it to dry.

If a keyboard does not work after trying it again later it is recommended that it be replaced. If the keyboard works but some of the keys are sticky or cannot be pressed in you can attempt to do additional cleaning in attempt to resolve the issue. Unfortunately many times when any sticky substance such as a non-diet pop is spilt directly onto the keyboard it's usually a loss unless you plan on spending dozens of hours attempting to clean each key.

Why? A keyboard that is used by multiple people, such as students or different employees, may need to be disinfected to help the spread of germs.

Procedure: Turn off the computer. Spray a disinfectant onto a cloth or damp a cloth with alcohol and rub each of the keys on the keyboard. As mentioned in our general cleaning tips, never spray any type of liquid onto the keyboard.

Headphones cleaning

2009-02-09T10:45:00.000-08:00

Why? Headphones that are used by multiple people may need to be cleaned frequently to help prevent the spreading of germs and head lice.

Procedure: If the headphones being used are plastic and/or vinyl, moisten a cloth with warm water and rub the head and earpieces of the headphones. As mentioned earlier in our cleaning tips, it is recommended that if your headphones are being used for a library or school that you do not use any type of disinfectant or cleaning solvent as users may have allergic reactions to the chemicals they contain.

Headphones that have cushions also have the availability of having the cushions replaced. Replacing these cushions can also help keep the headphones clean.

Finally, in regards to headphones and the spreading of head lice, if multiple students are using your headphones, you should consider having the students use their own headphones, using bags that are placed over the headphones, or having headphones that can be wiped with warm water after each student has used the headphones.

Floppy drive cleaning

2009-02-09T10:41:00.000-08:00

Why? Dirty read/write heads on the floppy drive can cause errors during the reading and/or writing process.

Procedures: The floppy drive can be cleaned two different ways. The first method of cleaning a floppy drive, and our recommended method, is to purchase a kit at your local retail store designed to clean the read/write heads on your floppy drive.

The second method of cleaning the floppy drive is only recommended for experienced computer users. Open the floppy drive casing and physically swab the read/write heads with a lint-free foam swab soaked in pure alcohol, free-on, or trichloroethane. When performing these steps, be extremely careful when cleaning the heads to ensure that you do not lock them out of alignment causing the floppy drive to not work. To help prevent the heads from becoming out of alignment, use a dabbing motion lightly putting the swab on the head and removing it, do not perform a side-to-side motion with the swab.

CD / DVD cleaning

2009-02-09T10:38:00.001-08:00

Why? Dirty CDs can cause read errors and/or cause CDs to not work at all.

Procedure: Cleaning CDs and DVDs should be done with a cleaning kit but can also be done with a normal clean cotton cloth or shirt. When doing this with a clean cotton cloth or shirt, wipe against the tracks, starting from the middle of the CD or DVD and wiping towards the outer side as shown in the below picture. Never wipe with the tracks; doing so may put more scratches on the disc.

It is recommended when cleaning a CD that water is used. However, if the substance on a CD cannot be removed using water, pure alcohol can also be used.

CD-ROM or other disc drive cleaning

2009-02-09T10:35:00.000-08:00

Why? A dirty CD-ROM drive or other disc drive can cause read errors with CD discs. These read errors could cause software installation issues or issues while running the program.

Procedure: To clean the CD-ROM drive we recommend purchasing a CD-ROM cleaner from your local retailer such as a local Radio Shack. Using a CD-ROM cleaner should sufficiently clean the CD-ROM laser from dust, dirt, and hair.

In addition to cleaning the drive with a special disc designed to clean drives users can also use a cloth dampened with water to clean the tray that ejects from the drive. Make sure however that after the tray has been cleaned that it completely dry before putting the tray back into the drive.

Also see our CD cleaning recommendation for steps on cleaning each of your CDs.

Case cleaning

2009-02-09T10:32:00.000-08:00

Why? Keeps the appearance of the computer looking new. During cleaning, if ventilation locations are found, these can be cleaned helping the case keep a steady airflow to the computer, keeping components cool and in good working condition.

Procedure: The plastic case that houses the PC components can be cleaned with a lint-free cloth that has been slightly dampened with water. For stubborn stains, add a little household detergent to the cloth. It is recommended that you never use a solvent cleaner on plastics.

Make sure all vents and air holes are hair and lint free by rubbing a cloth over the holes and vents. It is also helpful to take a vacuum around each of the hole, vents, and crevices on the computer. It is safe to use a standard vacuum when cleaning the outside vents of a computer; however, if you need to clean the inside of the computer, use a portable battery powered vacuum to prevent static electricity.

If you are looking for steps on cleaning the inside of the computer, please see our motherboard cleaning section.

Cleaning tools

2009-02-09T10:22:00.000-08:00

Although many companies have created products to help improve the process of cleaning your computer and peripherals, users can also use household items to clean their computers and peripherals. Below is a listing of items you may need or want to use while cleaning your computer or computer peripherals.

Keep in mind that some components in your computer may only be able to be cleaned using a product designed for cleaning that component; if this is the case, it will be mentioned in the cleaning tips.

Cloth - A cloth is the best tool used when rubbing down a component; although paper towels can be used with most hardware, we recommend using a cloth when ever possible. Caution: We only suggest you use a cloth when cleaning components such as the outside of the case, a drive, mouse, etc. You should not use a cloth to clean any circuitry such as the RAM or motherboard.
Water or rubbing alcohol - When moistening a cloth, it is best to use water or rubbing alcohol. Other solvents may be bad for the plastics used with your computer.
Portable Vacuum - Sucking the dust, dirt, hair, cigarette particles, and other particles out of a computer can be one of the best methods of cleaning a computer. Over time, these items can restrict the airflow in a computer and cause circuitry to corrode. Do not use a standard vacuum as it can generate a lot of static electricity that can damage your computer.
Cotton swabs - Cotton swaps moistened with rubbing alcohol or water are excellent tools for wiping hard to reach areas in your keyboard, mouse, and other locations.
Foam swabs - Whenever possible, it is better to use lint-free swabs such as foam swabs.

General cleaning Tips

2009-02-09T10:20:00.000-08:00

Below is a listing of general tips that should be taken when cleaning any of the components or peripherals of a computer as well as tips to help keep a computer clean.

Never spray or squirt any type of liquid onto any computer component. If a spray is needed, spray the liquid onto a cloth and then use that cloth to rub down the component.
Users can use a vacuum to suck up dirt, dust, or hair around their computer on the outside case and on their keyboards. However, do not use a vacuum for the inside of your computer as it generates a lot of static electricity that can damage the internal components of your computer. If you need to use a vacuum to clean the inside of your computer, use a portable battery powered vacuum designed to do this job.
When cleaning a component and/or the computer, turn it off before cleaning.
Never get any component inside the computer or any other circuit board damp or wet.
Be cautious when using any type of cleaning solvents; some individuals may have allergic reactions to chemicals in cleaning solvents and some solvents can even damage the case. Try to always use water or a highly diluted solvent.
When cleaning, be careful not to accidentally adjust any knobs or controls. In addition, when cleaning the back of the computer, if anything is plugged in, make sure not to disconnect any of the plugs.
When cleaning fans, especially the smaller fans within a portable computer or laptop it's suggested that you either hold the fan or place something in-between the fan blades to prevent it from spinning. Spraying compressed air into a fan or cleaning a fan with a vacuum may cause damage to some fans or in some cases cause back voltage.
Never eat or drink around the computer.
Limit smoking around the computer.

LED Printer

2008-11-07T11:49:00.000-08:00

Short for light emitting diode printer, LED printers were developed by Casio and are printers capable of printing at the same or close to the same quality as most laser printers. LED printers work much like laser printers but utilize a LED panel that recreates the image on a negatively charged drum. The areas where the light hits the drum become less charged, which attracts toner. The printer then transfers the toner from the drum to the paper and applies intense heat to fuse the toner to the paper.

Thermal printer

2008-11-07T11:44:00.000-08:00

A thermal impact printer or electrothermal printer is a type of printer that uses heated pins to "burn" images onto heat-sensitive paper. These types of printers are commonly used in calculators and fax machines; and although they are inexpensive and print relatively fast, they produce low resolution print jobs.
A thermal printer, thermal transfer printer, or thermal wax-transfer printer is a high quality printer that commonly utilizes a thermal wax ribbon that melts a colored wax onto the paper creating near photo-realistic images.

Laser printer

2008-11-07T11:39:00.000-08:00

First developed at Xerox PARC by Gary Starkweather and released in 1971, a laser printer is a type of printer that utilizes laser technology to print images on the paper. Laser printers are often used in corporate, school, and other environments that require print jobs to be completed quickly and in large quantities. To the right is an example of what a laser printer may look like. This picture is of the Lexmark C782n laser printer. Finally, below is a chart of the steps a laser printer takes to print.

STEP	WHAT IT DOES
Cleaning	Removes prior image information and toner from the drum.
Conditioning	Applies a uniform negative charge to the drum.
Writing	Light source such as lasers, LED, or LCS (Liquid Crystal Shutter) write to areas on the drum discharging the negative potential where it hits.
Developing	The toner is ionized with a negative charge and is attracted to the areas previously written (discharged) on the drum.
Transfer	The toner of the drum is transferred to the paper by either a positively ionized field (created by a transfer corona wire) or by a transfer roller in newer printers. The toner is not yet permanently set on the paper and requires the last stage.
Fusing	Heat and pressure are applied to the paper and toner. The toner melts and then is pressed to the paper like doing an iron-on transfer to a T-shirt.

Inkjet printer

2008-11-07T11:24:00.000-08:00

A popular type of printer for home computer users that prints by spraying streams of quick-drying ink on paper. The ink is stored in disposable ink cartridges. often a separate cartridge is used for each of the major colors. These colors are usually Black, Red/Magenta, Green/Cyan, and Yellow (CYMK). Although inkjet printers themselves are often relatively inexpensive, the ink cartridges used in the printers can quickly increase the overall cost of the printer.

DOT matrix

2008-11-07T11:14:00.001-08:00

The term DOT matrix refers to the process of placing dots to form an image; the quality of the image being determined by the dots per inch.
Dot matrix printers were first introduced by Centronics in 1970 and is a type of printer that uses print heads to shoot ink or strike an ink ribbon to place hundreds to thousands of little dots to form text and/or images. Today, dot matrix printers are not commonly used or found because of the low quality print outs when compared to ink jet printers or other later printer technologies.
