2-1-7 Fuser section
(1) Fuser unit
The fuser section consists of the following parts and fixes the toner that is transferred to the paper at the transfer/separa-
tion 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 lamp installed inside, 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 fuser thermistor detects the temperature
of the surface on the heat roller heated by the fuser heater lamp and this temperature is controlled by the engine PWB. If
the fuse section shows extremely high temperature, the power line will be shut off and the fuser heater lamp is forced to
turn off. When fusing of toner is complete, the paper is separated from he heat roller by the separator and ejected to the
paper eject section/rear unit.
