11. IMAGE FUSING
11.1 OVERVIEW
After the image is transferred, the copy paper enters the fusing unit. The
image is fused to the copy paper by heat and pressure using a hot roller [A]
and a pressure roller [B].
The CPU monitors the hot roller temperature through a thermistor [C] which
is in contact with the hot roller surface. A thermofuse [D] prevents 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. The exit sensor [F] monitors the progress of the
copy paper through the fusing unit and acts as a misfeed detector. The exit
rollers [G] drive the copy paper to the copy tray.
