Subject:
Troubleshooting Stuck Lock Lever of the Drum
Cleaning Unit
From:
1st PP Tech Service Section, PP Tech Service Dep.
Classification:
This RTB is targeted only for NA.
SYMPTOM
The drum cleaning unit lock lever could be stuck, making it impossible to remove the drum
cleaning unit from the PCDU.
The lever will not turn
counterclockwise to
release the lock.
CAUSE
The drum cleaning unit is set in the PCDU by turning the lock lever clockwise, which fixes
the pin that protrudes from the development unit with the hollow shaft on the drum
cleaning unit. However, the tip of the hollow shaft could be rough on its surface and this
disables the release of the pin on some units.
