Fusing Method
A certain temperature and pressure are applied to the paper fed from the transfer unit to fuse the toner to the paper.
A contact thermistor is mounted on the center of the hot roller to detect the temperature and turn the fusing lamp on and
off. To prevent overheating, a thermostat is mounted at the center and a contact thermistor is mounted at one of the
ends.
Fusing Pressure, Separation, Exit
Pressure is applied at all times to the hot roller and fusing pressure roller by springs.
The fused paper is separated from the hot roller by the hot roller strippers, and then delivered to the paper exit.
Fusing Drive
The main motor drives the fusing unit (hot roller and fusing exit roller) through a gear train.
