Common application methods and fault analysis of scanners (III)

III. how to clean scanners. As we all know, scanners are very sophisticated equipment with many optical components. If they are dirty, they will certainly affect the scanning effect. However, we can not only use it in a dust-free environment, which is too unrealistic. Since it is impossible to nip the problem in the bud, we have to work harder afterwards, so regular cleaning is certainly indispensable

well, the cleaning has begun. First of all, we should take a soft cloth to wipe the scanner shell (excluding the glass plate). Its purpose is to sweep away the floating dust on the surface and prevent the shell from getting more scratched when wiping with water. Next, carefully wipe the shell with a wet cloth. Pay attention not to make the cloth too wet. It is best not to have water flowing out during the wiping process. With the smaller volume of the working room available for aerospace, national defense, kerosene chemical industry and transportation, the transportation and other people's economic tension will be adjusted and upgraded. In some places with thick dirt, you can dip some washing powder on the wet cloth, and then wipe it hard. Finally, don't forget to wipe the place with washing powder again with a clean wet cloth

next, open the scanner. Before that, you'd better lock the security lock behind it. If you find that the dust inside is thick, you can blow it with a blowing balloon. Then you can wait for the dust to fall. Don't forget to cover the scanner during this period, otherwise what you just did will become useless. Take advantage of this time, you can buy a bottle of distilled water in the supermarket, and finally find a small ball of absorbent cotton for standby

find its hair and stress axis 1 light emitting tube and reflector in the optical components of the scanner, and wet the absorbent cotton with distilled water. The degree of dryness and wetness is better if there is no water after hard extrusion. Then carefully wipe the light-emitting tube and reflector (see Figure 1). Be careful not to change the position of optical accessories

if you find that the scanner moves with some noise during use, it may be that the sliding rod is short of oil or there is dirt on it. You can find some lubricating oil to wipe on the sliding rod (see Figure 2), increase its lubrication degree, and the noise problem can be basically solved

after all the inside is cleaned, install the machine, and finally wipe the flat glass of the scanner with a clean wet cloth. Then you will see a brand-new scanner in front of you
