1, Remove
the
photoreceptor drum assembly
from the xerographic module (REP 9.2).
2. Put on gloves.
3. Gently remove any dry ink
/
toner and
developer from the surface of the drum,
using a dry polyurethane pad.
4.
Completely soak two sponges with water.

i s only slightly damp.
6. Using another paper towel, remove some
water from the second sponge until
it
i s
drier than the first sponge.
7.
Shake the container of polish thoroughly.
8.
Put a large amount of polish on a clean
polyurethane pad.
Q Ensure that the entire surface of the
drum
is
polished.
10. Remove the polish from the drum, using
the first sponge. Then remove any residual
polish, using the second sponge.
11. Buff the surface of the drum, using the
clean side of the dry polyurethane pad.
12. Use the dusting pouch in order to apply
a
thin layer of zinc stearate over the entire
surface of the drum.
13. Buff the surface of the drum again.
Q Ensure that the ends o f the drum are
buffed as well as the center of the
drum.
14. Contmue to buff the surface of the drum
for three complete revolutions of the
drum.
15.
Apply a final thin layer of zinc stearate
over the entire surface
of
the drum.

Polish the drum.
After completing the polishing
procedure, the drum must be used
immediately. I f the drum is stored,
crystallization problems may occur.
16. Reinstall the drum.
