If, however, the surface is contaminated with fingerprints, clean it using the following proce-
dure.
Notes:
• The Organic Photoconductor Drum is softer than CdS and Selenium Drums and is there-
fore susceptible to scratches.
• 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.
1. Place the PC Drum into one half of its container.

2. Gently wipe the residual toner off the surface of the
PC Drum with a dry, dust-free cotton pad.
• 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.
• 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 isopro-
pyl 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 move-
ment 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 proce-
dure 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 com-
plete turns of the PC Drum would be appropriate for
cleaning.
