The diagram shows the fusing unit (on the right) and the exit unit (on the left),
which directs paper either down to the inverter/duplex unit, or out to the copy tray
or finisher.
ˆ
The fusing and exit units have been made into separate modules, which can be
easily separated from each other. This makes part replacement easier.
ˆ
Briefly, outline the components of the fusing unit as explained in the service
manual.
ˆ
Note the web cleaning unit, which contains a web moistened with silicone oil for
cleaning the hot roller.
