SERVICE
1. Before troubleshooting a particular problem, consult the operator to obtain clues that may assist in
finding the problem. Who would be more familiar
with the symptom of the problem than the individual that constantly operates the machine.
2. Copy Samples
Always make copy samples before and after your
maintenance service to ensure proper machine
operation.
3. Drum
• Do not expose the drum to sunlight or room light.
When the drum is removed from the machine, place a
cover over it.
• When cleaning the photosensitive surface, use a
cleaning pad moistened with the specified drum
cleaner.
Never use solvents other than the drum cleaner;
otherwise the photosensitive material of the drum can
be dissolved.
4. After maintenance is completed, remember to
reset the PM counter. (47 mode, Code 90/See the
adjustment section for details.)
5. Always reset the drum counter when replacing the
drum. (47 mode, Code 91/See the adjustment
section for details.)
Caution
Be sure to turn the main switch OFF and pull the
plug before working on the machine.
