The drum cleaning blade is also called a cleaning blade, which is closely attached to the surface of the photosensitive drum. During the printing process of the printer, the toner forms an image on the toner cartridge and then transfers it to the printing paper. The drum cleaning blade manufacturer tells you that there will be a small amount of toner remaining on the surface of the photosensitive drum during the transfer process. If it is not removed, it will affect the printing quality of the next sheet. The function of the cleaning blade is to clean the residual toner on the surface of the photosensitive drum.

The drum cleaning blade manufacturer tells you that the cleaning blade is composed of a metal frame and a rubber sheet, and the quality of the blade also directly affects the service life of the toner cartridge. A good cleaning blade material looks translucent with a tinge of yellow and moderate hardness.
The drum cleaning blade manufacturer tells you that the scraper rubs against the drum core for a long time, and the rubber blade will be chipped and deformed. When the cleaning blade is chipped or worn, bottom ash or vertical black lines will appear on the printing paper.
When a vertical black band appears on the printed product, you can try to replace the scraper to troubleshoot the problem. The drum cleaning blade cannot be repaired after wear and tear, and the fault can be solved by replacing it directly.
