Rubber roller (Lower sleeved roller, Pressure roller) is one of the main components of the fuser assembly of a laser printer, responsible for the tight and uniform adhesion of a sheet of paper with applied toner to the heating roller. As a result, thanks to its pressure and heating by a thermocouple, the toner fuses into the paper fibers and the image is fixed. It consists of a metal rod and a layer of heat-resistant rubber applied to it.
The most common reasons for the failure of the rubber shaft:
The most common reasons for the failure of the rubber shaft:
- mechanical damage, when paper with paper clips or staples hits the thermal unit;
- twisting, deformation and rupture of the surface of the rubber shaft as a result of exceeding the peak printing loads and overheating of the thermal fixing unit;
- natural wear of the rubber shaft when passing through the declared print resource of the thermal unit.
