After the image is transferred, the copy paper enters the fusing unit.
The image is fused to the copy paper by the process of heat and pressure
through the use of a hot roller [A] and pressure roller [B].
The CPU monitors the hot roller surface temperature through a thermistor [C]
which is in contact with the hot roller's surface. A thermoswitch [D] protects
the fusing unit from overheating.
The hot roller strippers [E] separate the copy paper from the hot roller and
direct it to the exit rollers [F]. The exit sensor [G] monitors the movement of
the copy paper through the fusing unit and acts as a misfeed detector. The
exit rollers drive the copy paper to the copy tray.
