Background

Fusing refers to the process of fixing a developed image to a copying medium (e.g., paper) using some method. Examples of the fixing method of the electrostatic copier include thermal plate fixing, thermal radiation fixing, thermal roller fixing, cold press fixing, and chemical fusion fixing. Fixing is a process of fixing an unstable, erasable toner image on a copy sheet to the sheet, and the toner image transferred to the copy sheet by a transfer and separation process is not integrated with the copy sheet, and the toner image is extremely erased at this time, and therefore, it is required to be solidified by a fixing device to form a final copy product. The fuser is a component of a laser printer. The middle of the fixing lower roller is a steel solid roller, most of the middle (corresponding to the fixing upper roller) is coated with a rubber layer with the thickness of about 0.8CM, the rubber layer is generally red, and a thin chemical film with the high temperature resistance (about 80 degrees) is coated on the rubber layer. Its main function is to press the fixing upper roller, which is not itself driven. The rotation power is from the friction of the fixing upper roller, and the rotation of the fixing upper roller can fix the copied carbon powder image through high temperature and send the copied carbon powder image out to a paper output tray of the copying machine.

When the fixer is used, in order to ensure that printed matters can be conveyed out, a lower roller assembly is generally arranged in the fixer and used for pressing an upper roller, so that printed matters are conveyed out, most of lower roller assemblies of most of the existing fixer are fixed in the fixer, the lower roller fixed in the fixer is required to be detached and taken out when the fixer is damaged and needs to be replaced, and the fixing device is difficult to detach and poor in practicability.
