3. SERVICE REMARKS
3.1 GENERAL CAUTION
To prevent physical injury, keep hands away from the mechanical drive
components in the following two cases:
a. If the Start key is pressed before the copier finishes the warm-up cycle,
(Ready indicator starts blinking) the copier starts making copies as
soon as the warm-up cycle is completed.
b. If the main switch is turned on while the first cassette is in the down
position, the main motor starts rotating as soon as the warm-up period
is completed.
3.2 DRUM
1. Never touch the drum surface with bare hands.
2. Store the drum in a cool dry place.
3. Always wear gloves when cleaning the drum.
4. Do not leave the drum exposed to light for long periods of time.
5. Drum Initial Setting (SP No. 66) must be done after installation of a new
drum.
NOTE: Drum initial setting does not need to be done when a new machine
is installed; this is done at the factory.
6. Always keep the drum in the protective sheet when inserting or pulling the
drum out of the copier. This protects the drum from light, thus preventing
drum fatigue.
7. Before inserting or pulling out the drum, do the following to prevent drum
damage:
a) Remove the cleaning unit.
b) Remove the development unit.
c) Remove the charge corona unit.
d) Lower the transport unit.
8. Before pulling out the drum, place a sheet of paper under the drum to
catch any dropped toner.
9. Dispose of used drums according to local regulations.
