If, however, the surface is contaminated with fingerprints, clean it using
the following procedure.
1. Place the PC Drum into one half of its carton.
2. Gently wipe the residual toner off the
surface of the PC Drum with a dry, Dust-
Free Cotton Pad.
A.Turn the PC Drum so that the area of its
surface on which the line of toner left by the
Cleaning Blade is present is facing straight
up. Wipe the surface in one continuous
movement from the rear edge of the PC
Drum to the front edge and off the surface
of the PC Drum.
B. Turn the PC Drum slightly and wipe the
newly exposed surface area with a CLEAN
face of the Dust-Free Cotton Pad. Repeat
this procedure until the entire surface of the
PC Drum has been thoroughly cleaned.
*At this time, always use a CLEAN face of the dry
Dust-Free Cotton Pad until no toner is evident on
the face of the Pad after wiping.
3. Soak a small amount of either ethyl alcohol
or isopropyl alcohol into a clean, unused
Dust-Free Cotton Pad which has been
folded over into quarters. Now, wipe the
surface of the PC Drum in one continuous
movement from its rear edge to its front
edge and off its surface one to two times.
*Never move the Pad back and forth.
4. Using the SAME face of the Pad, repeat the
procedure explained in the latter half of
step 3 until the entire surface of the PC
Drum has been wiped. Always OVERLAP
the areas when wiping. Two complete turns
of the PC Drum would be appropriate for
cleaning.
NOTE:
Even when the PC Drum is only locally dirtied, wipe the entire
surface.
Do not expose the PC Drum to direct sunlight. Clean it as
quickly as possible even under interior illumination.
If dirt remains after cleaning, repeat the entire procedure from
the beginning one more time.
