Upper Rollers

Copier The fixing roller is the main unit for fixing the photocopaired toner image by the copier, which is the key part of the fixing part of the copier. It consists of fixing the upper roller and the fixing roller.
The fixing roller is located at the upper portion of the fixing device, and the high temperature required for fixing is transferred from the portion and applied to the toner image on the copy paper. It is an aluminum hollow tube, coated in its outer layer of high temperature (usually about 180 degrees) of the chemical coating, hollow part of the device used to produce high temperature fixing lamp, the coating part is generally black, there are Other colors, shiny, both ends are relatively thin, is used for fixed and loaded drive gear.
The middle of the roll is a solid steel roll, in the middle of most of the (corresponding to the fixing roller) wrapped about 0.8CM thick rubber layer, generally red, in the rubber layer wrapped with a thin layer of high temperature (about 80 degrees or so) of the chemical film. Its main role is to press the roller on the fixing, which itself is not driven. The power of its rotation comes from the frictional friction of the fuser, which rotates with the fuser roller to fix the toner image through high temperature and send it to the output tray of the copier.
