(7) Fusing
After the end of the transfer, the unfused toner image is fused on the paper under heat and
pressure as it passes between the heater roller and the back-up roller. The heater roller with
a Teflon coating incorporates a 750W heater (Halogen lamp), which heats the heat roller.
A thermistor which is in contact with the heater roller regulates the heater roller at a
predetermined temperature (about 180 ~ 200 C). A safety thermostat cuts off voltage supply
to the heater by opening the thermostat in the event of abnormal temperature rises.
The back-up roller is held under a pressure of 5 kg from the pressure spring at each side.
