Belt and Rollers
Development drive motor-K drives the pressure roller [E] and the hot roller [D]
through the gear train. The heating roller [C] is driven by the pressure with the
fusing belt [B]. The cleaning roller [G] and oil supply roller [F] are driven by the
friction with the pressure roller.
Fusing Clutch
The fusing clutch [A] turns off and cuts the drive power when the fusing unit does
not operate. This mechanism prevents wear on the belt and rollers.
NOTE: The fusing clutch turns off when images and patterns are created on the
transfer belt during process control and line position adjustment.
