(7) Fuser section
The paper sent from the transfer/separation section is interleaved between the heat roller and the press roller. The heat
roller is heated by the fuser heater, and the toner is fused by heat and pressure and fixed onto the paper because the
press roller is pressed by the fuser press spring. The surface temperature of heat roller is detected by the fuser
thermistor and controlled by the engine PWB. If the fuser section shows extremely high temperature, the power line will
be shut off and the fuser heater is forced to turn off.
