2.5.08 Fusing

After transfer, the toner image is fused to the paper by heat and pressure. The paper passes
between the fusing roller and the pressure roller. The fusing roller has a teflon coating and
contains a 400 watt halogen lamp. A thermistor (which contacts the fusing roller) maintains the
fusing roller temperature at approximately 150 degrees Celsius. A thermostat cuts off the voltage
supply to the lamp if there is an abnormal temperature rise.
The pressure roller provides 2.5 Kg of pressure. This is generated by the pressure springs at each
side of the roller.
