Scanner as an image input device, has been popularized to thousands of households, the following I'll share with you scanner cleaning tips, welcome to read!
Scanner cleaning tips
Preparation: Before cleaning, the scanner lens lock (also known as the safety lock) should be dialed to the locked position, which can avoid damage to the scanner's optical components due to shaking during the cleaning process. The scanner safety lock is usually located on the bottom of the machine, or on the side of the machine with an indicator mark. With the scanner's power off, tilt the scanner slightly, as shown in the figure below, and press the scanner's safety lock with your finger, then push it to the position of the up-lock symbol. Then prepare the necessary tools: a couple of dry, soft cotton cloths, a leather tiger blower, degreasing cotton wool, water, glass cleaner, lubricant, etc.
Step 1: Cleaning the case
We all have the experience that when wiping the surface of a dusty object directly with a wet cloth, it will make the surface very flowery. Therefore, it is best to take a dry, soft cotton cloth to remove the dust from the scanner housing, and then wipe it again with a damp cloth, so that the dust is basically "eliminated". If there are some other stains on the shell at this time, we can dip a damp cloth in some laundry detergent to remove. After cleaning, remember to use a clean damp cloth to wipe the place with laundry detergent several times, so as not to residual detergent or laundry detergent lead to discoloration of the shell.
When cleaning the housing, we should be careful not to touch the scanner glass plate, and should also wring out the wet cloth as much as possible, so as to avoid dirty water in the wiping process to dirty the flat glass.
Step 2 Clean the glass flat panel
After the shell is basically dry, open the top cover of the scanner, and if the dust inside accumulates thicker, you can use the skin tiger duster to blow a few times against the flat glass, and "drive away" the dust that adheres to the surface. For stains that can not be blown away, we must use glass cleaner to clean, and then wipe clean with a soft dry cotton cloth. As the glass panel clean or not directly related to the image of the scanning quality, so we must be careful when cleaning the panel, not furtive.
Step 3 Clean the internal optics
Next we can open the scanner's flat glass to clean the scanner's internal optics. Generally speaking, the scanner's case and base are stuck together, so it can be easily removed without a screwdriver, and during the removal process, be careful not to disrupt the wiring under the key panel. In the optical components we have to focus on cleaning is the scanner's light tube, reflector: with a degreasing cotton ball dipped in distilled water, and then the cotton ball on the water with the strong squeeze out (to ensure that there will be no water flow in the wiping process), wet and dry degree of pressure with the strong squeeze out of the water as good. Then gently wipe back and forth on the light-emitting tube, reflector. Since optical components are relatively precise, move gently and smoothly when cleaning these devices. In addition, if dust gets into the joints between the gauge and the glass plate, then the gauge must be replaced.
Step 4 Clean the Drive
The sliding bar on the scanner's drive mechanism is another key point of concern. Usually, when the scanner is noisy during the working process, it may be that the sliding bar is out of oil or has accumulated dirt on it. At this point, we can find some lubricant evenly coated in the sliding rod, to increase the degree of lubrication, the noise problem can be basically solved.
After all the above cleaning work is done, and then in the right order to install the scanner debugging, cleaning the scanner work is complete.

1. Generally speaking, home scanners are EPP interfaces, and after the scanner has been powered on, if you hot swap the interface's data transfer cable at any point in time, it will damage the scanner's or computer's interface, and it will be more of a hassle to replace it, with the exception of USB interfaces, which are of course supported by hot swap. The scanner can also be used as a stand-alone device.
2. Please do not cut off the power when the scanner is working, generally wait until the scanner's mirror group is completely back to the position, and then cut off the power, which is very meaningful to the normal work of the scanner circuit chip.
3. As some CCD scanners can scan small three-dimensional items, the instrument should be careful when scanning: do not move around when placing sharp objects so as not to scratch the glass, including reflective scripts on the staples; do not put down the upper cover with too much force, so as not to break the glass.
4. Some scanners are not designed to completely cut off the power switch, when the user does not use, the scanner lamp is still on, because the scanner lamp is also a consumable (analogous to fluorescent lamps, but the duration of use to be a lot longer), so it is recommended that users do not use cut off the power supply.
5. The scanner should be placed away from windows, as there is a lot of dust near windows and direct sunlight, which reduces the lifespan of the plastic parts.
6. As the scanner will produce static electricity in the work, which will adsorb a lot of dust into the body to affect the work of the mirror group. Therefore, do not cover with fabrics that are easy to fall off (velvet products, cotton fabrics, etc.), you can use silk or batik cloth, etc. to cover, and the proper humidity of the room can avoid the impact of dust on the scanner.
