9.3.5 Fusing Drive Release Mechanism
The fusing unit drive release mechanism automatically disengages the
fusing unit drive gear [A] when the front door is opened.
When the front door is opened, the fusing knob [C] is pushed outwards
(white arrow inset) by the spring joints [B] in the fusing drive shaft. The
fusing knob [C] now fits over the hub [D] at the end of the fusing drive shaft.
This allows the user to turn the hot roller to remove jammed paper.
Also, when the door is opened, the release shaft [F] is shifted to the front
side by the spring [E]. Then the fusing unit drive gear is released. This allows
the fusing unit drive gear to rotate freely so that misfed paper can be easily
removed.
