Printing device drive gear worn, loose or not lubricated. The reason is that due to the long-term operation of the driving wheel of the printing apparatus, wear, looseness, or non-lubrication is caused, resulting in a mismatch between the gear and the gear, between the driving wheel and the cartridge, and an abnormal sound occurs. Treatment method: tighten the gear or replace it. If it is not lubricated, add solid lubricant to some gears.
Improper fitting of internal components of the drum assembly causes the resistance during the operation of the drum assembly to be greater than the driving resistance of the printing device, resulting in abnormal noise. Judgment method: Put the handle on the gear end of the HP CE505X, and push it in the direction of the protective cover to check if the resistance of the cartridge is normal. In addition to the drum assembly of the Samsung series, it can be easily pushed.
Improper Assembly of Drum Assembly Causes the Drum to Fail to Operate. Due to the assembly error of the drum assembly, the drum assembly may not operate normally or the resistance during the operation exceeds the driving resistance of the printing apparatus, causing an abnormal sound. Judgment method: Put the handle on the gear end of the toner hp cf217a, and push it in the direction of the protective cover to check if the resistance of the cartridge is normal. In addition to the drum assembly of the Samsung series, it can be easily pushed.
Drum Assembly Elastic compression springs or tension springs are installed incorrectly, fall off, or aged. During drum assembly operation, the resistance or tension between the silo and the waste toner box is too small, and the gears of the drum assembly are in poor contact, causing abnormal noises. Judgment method: Check whether the elastic compression spring or tension spring at the joint between the drum unit and the waste toner box is installed correctly. Push the powder bin and the waste toner bin by hand to see if the spring is aging. Replace the spring or install it. OK spring.
