1-5-7 Fuser and eject/feedshift 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 (FUH), 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 main/engine PWB (MEPWB). If the fuser
section shows extremely high temperature, the power line will be shut off and the fuser heater (FUH) is forced
to turn off.
The paper eject/feedshift section consists of the conveying path which sends the paper that has passed the
fuser section to the inner tray or the duplex conveying section.
