15) Remove the 2 screws [1] and detach the drum drive unit (C).
[Reference] To detach the hopper unit (Bk), remove the drum drive unit (Bk) as
well as the drum drive unit (C).
[Caution] When installing the drum drive unit (C), go through the following steps so
that no gap is found at the main body's rear side plate.
1) Install the drum drive unit (C) and temporarily tighten the 2 screws.
2) Hold the 2 levers of the process unit inner cover and raise the levers and the
process unit inner cover at a 90-degree angle.
3) While keeping the levers horizontally, push the process unit inner cover to the rear
side. Then, push on the 2 stopper plates [A] of the right and left hooks of the process
unit inner cover to the end faces [B] of the hinge shaft holder at the right and left
sides of the main body. If the process unit inner cover is pushed to the rear side
without keeping the levers horizontally, the 2 stopper plates [A] of the hooks run over
the inside of the hinge shaft holder at the right and left sides of the main body,
which may cause the release arm inside the process unit inner cover to get
damaged.
