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 
and press roller are detected by the fuser thermistor (FTH) and controlled by the main PWB (MPWB).
