What is a cleaning blade?

• What is a wiper blade in a printer?

Cleaning blade, also known as wiper blade. In linear contact with the photosensitive drum, clean the toner that has not been completely transferred on the surface of the photosensitive drum. It consists of a metal base frame and a polyurethane sheet.

• Use:

The cleaning blade is one of the accessories of the toner cartridge. The cleaning scraper is an important part of the toner cartridge. Its main function is to clean. The glass fiber reinforced glass is equipped with wear-resistant materials, alicyclic adhesives, and a rated temperature of 150℃. The excellent mechanical characteristics of this material ensure the perfect and clean operation of the scraper and good working performance.

• How it works:

During the printing or copying process of the printer or photocopier, the toner forms an image on the toner cartridge and then transfers it to the copy paper. During this process, a part of the toner will remain on the toner cartridge. If this part is not removed, it will be transferred to the next copy paper when copying the next piece, which will affect the copying effect and quality of the next piece. At this time, there is a need to have a device that removes the toner remaining on the toner cartridge after copying one of the copies. This device is a cleaning blade.

• How to judge the quality?

The quality of a blade is very important, it directly determines the quality of the copy and the service life of the toner cartridge. The quality of the blade is mainly determined by its material, hardness and smoothness. The material of a good cleaning blade looks translucent, white and yellow in color; moderate hardness; smooth and without deformation.

• Maintenance knowledge:

The cleaning blade is one of the printer toner cartridge accessories. The cleaning blade and the doctor blade are very similar to the composition, except that it uses slightly harder polyurethane rubber. Of course, its function is not the same as that of a doctor blade.

The state of the rubber material and the blade edge of the cleaning blade are very important. After long-term use, the rubber will melt and deform, and there will often be gaps in the blade edge. Such a cleaning blade cannot be used anymore, and local bottom gray or vertical light black lines will appear on the print product.

The copy of the photocopier must be fixed at a certain pressure through a high temperature of about 180 degrees. During this process, a small amount of toner will be attached to the fuser roller, and the cleaning of these contaminations must be done by the cleaning blade of the fixing roller. The blade quality of the fixing roller is mainly made of material and must withstand high temperatures.
