Fusing - OKIDATA OL600e Service Manual

Fusing

When the image transfer is completed, the toner image is fused to the paper by heat
and pressure as the paper with the toner image passes between the heater roller and
the back-up roller. The heater roller has a Teflon coating. A 400W heater (Halogen
lamp), inside the roller provides the heat needed for fusing.
A thermistor, which is in contact with the heater roller, regulates the temperature of
the heater roller (about 165 degrees Celsius). 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 kilograms applied by the pressure
spring on each side.
