Step / Method: 1, cleaning the shell We all have the experience that when you wipe the surface of a lot of dust directly with a damp cloth, the surface will be very flowery. Therefore, it is best to remove the floating ash covered by the barcode scanner housing with a dry soft cotton cloth, and then wipe it again with a damp cloth, so that the dust can be basically "killed". If there are some other stains left on the outer casing, we can remove some washing powder on the damp cloth. After cleaning, wipe the place with the washing powder several times with a clean damp cloth. When cleaning the outer casing, we should be careful not to touch the glass plate of the barcode scanner. At the same time, we should wring the wet cloth as much as possible to avoid the dirty water flowing out of the dirty flat glass during the wiping process. 2, cleaning the glass plate After the outer casing is basically dry, open the top cover of the barcode scanner and blow it with a blown balloon to the flat glass to "run away" the dust attached to the surface. For stains that cannot be blown away, use a glass cleaner to clean them, then wipe them off with a soft, dry cotton cloth. Since the cleanness of the glass panel is directly related to the scanning quality of the image, we must be careful when cleaning the panel. 3. Cleaning the internal optical components Next we can open the flat glass of the barcode scanner and clean the optical components inside the barcode scanner. In general, the frame and base of the barcode scanner are carded together, so they can be easily removed without a screwdriver. In the optical components, we should focus on the bar code scanner fluorescent tube: use a cotton wool ball to pour distilled water, and then squeeze the water on the cotton ball to ensure that no water will flow out during the wiping process. Wipe back and forth on the tube. Due to the precision of the optical components, when cleaning these devices, the action is light and stable. 4, cleaning transmission The slider on the bar code scanner drive is another important point for us to pay attention to. Usually when the bar code scanner is noisy during operation, it is likely to be a problem with the slider. At this point we can find some lubricant evenly applied to the sliding rod to improve the mechanical lubrication of the transmission mechanism. After the above cleaning work is completed, the barcode scanner is installed and debugged in the correct order, and the work of cleaning the barcode scanner is completed. The maintenance of the barcode scanner is relatively simple, mainly paying attention to the following points: 1, anti-fall. The internal structure of the barcode scanner is composed of a decoder component and a main board. These components are relatively precise components. Therefore, when using it, it should be avoided to fall from a high place, especially the glass component of the barcode scanner. This will cause dust to enter the barcode scanner. 2, anti-strength pull. The barcode scanner is a combination of a wire and a bar code gun. It is often pulled hard, which makes it easy to loosen the joint and cause poor contact during scanning. 3. Clean the glass blank frequently.
