(6) Fusing
When the paper passes through the heat roller and backup roller unit, heat and
pressure are applied to the toner image on the paper and the toner is fused onto
the paper.
The halogen lamps
of 800W and 400W are built in heat roller. The backup roller
without built-in halogen lamp is heated by the heat transmission from the heat
roller. The fusing temperature is controlled by the temperature detected by the
thermistor that is not in contacting with the surface of the heat roller. On the
other hand, the temperature detected by the thermistor rubbing the surface
of backup roller is used for controlling the fusing temperature under specified
conditions. Furthermore, a thermostat is used to limit the temperature rise, if
the temperature rise of heat roller exceeds a set point, the thermostat would be
open and the voltage supply to the heater would be cut off. The backup roller
unit is pressed on the heat roller by the spring on both sides.

Drum cleaning
