2-1-6 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 (FH), 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 (FTH) and controlled by the engine PWB (EPWB). If the fuser section
shows extremely high temperature, the power line will be shut off and the fuser heater (FH) is forced to turn
off.
