(6) Fusing
When the transfer is completed, the toner image is fused to the paper by heat and pressure as the
paper with unfused toner image passes between the heater roller and the back-up roller. The heater
roller with Teflon coating incorporates a 400W heater (Halogen lamp), which generates heat.
A thermistor which is in contact with the heater roller regulates the temperature of the heater roller
to a designated temperature in the menu, depending on the thickness of the paper (tray 1&2:

C). A safety thermostat cuts voltage supply to
the heater off by opening the thermostat in the event of abnormal temperature rises.
The back-up roller is held under a pressure of 3.76 kg applied by the pressure spring on each side.
