Fusing Drive Release Mechanism - Ricoh FT4460 Service Manual

10.2 FUSING DRIVE RELEASE MECHANISM

The fusing unit drive release mechanism automatically disengages the fusing
unit drive gear [A] when the front cover [B] is opened. This allows the fusing
unit drive gear to rotate freely so that jammed paper can be easily removed.
When the front cover is opened, the safety lever is released and the release
shaft [D] rotates as shown above. This moves the release pin [E] upwards,
thus disengaging the fusing unit drive gear from the hot roller gear.
The leaf spring [F] forces the fusing unit drive gear downwards and keeps it
engaged when the front cover is closed.
