Fusing
The transferred unfused toner image is fused to a sheet of paper because heat and pressure are applied when
it passes between the heat roller and backup roller.
The Teflon-coated heat roller contains a 400 W heater (Halogen lamp) that heats the heat roller. The
thermistor on the surface of the heat roller keeps the temperature of the heat roller constant. A thermostat
is also installed for safety. If temperature rises abnormally, this thermostat opens to suspend voltage
supply to the heater.
The backup roller is pressurized to the heat roller by the pressure spring on each side.

Cleaning
After transfer has terminated, the cleaning roller temporarily draws in the untransferred residual toner
adhering to the image drum with static electricity and then returns it to the image drum.
