The following part was added as an individual service part.
Reason: To prevent drum scratching caused by narrower PG.
Fastening the drum knob incompletely will cause the drum cleaning unit to apply pressure
to the drum and narrow the PG at the front side. Then, developer piled up on the mag
roller will scratch the drum.
This tool assists the tightening drum knob completely, because the drum knob might be
incompletely tightened when it is done without the tool.
