1. SERVICE REMARKS
1.1 GENERAL CAUTIONS
1. To prevent physical injury, keep hands away from the mechanical drive
components when the main switch is on (especially during the warm-up
cycle).
If the
key is pressed before the copier finishes the warm-up cycle,
the Start indicator starts blinking and the copier starts making copies as
soon as the warm-up cycle is completed.
2. Before disassembling or assembling any parts of the copier, make sure
that the power cord is unplugged.
1.2 IMAGING UNIT
1. Always ensure the following when removing the imaging unit from the
copier.
•
Do not touch the drum surface with bare hands. When the drum
surface is touched with fingers or becomes dirty, wipe it with a dry
cloth.
•
Place the imaging unit on a clean and level place. Take care not to
scratch the drum from under the unit as there is no cover to protect it.
•
Cover the imaging unit with sheets of paper to prevent the drum from
being exposed to light.
•
Do not turn the imaging unit upside down. Toner and developer may
fall out from the unit.
2. Before pulling out the imaging unit, place a sheet of paper under the unit
to catch any spilled toner.
3. Never use alcohol to clean the drum; alcohol dissolves the drum surface.
4. Take care not to scratch the drum as the photoconductive layer is thin
and is easily damaged.
5. Never expose the drum to corrosive gases such as ammonia gas.
6. Store the imaging unit in a cool, dry place away from heat.
7. Do not touch the charge corona wire or the grid plate with bare hands. Oil
stains may cause uneven image density on copies.
8. Clean the charge corona wire by pulling on the wire cleaning knob.
9. Clean the charge grid with a blower brush (not with a cloth).
