Fusing
When the image 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
heats the heat roller.
A thermistor which is in contact with the heater roller regulates the temperature of the
heater roller at a predetermined level (about 165
°
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 3.8 kg applied by the pressure spring on
each side.
