2. Gently wipe the residual toner off the surface of the PC
Drum with a dry, Dust-Free Cotton Pad.
a) Rotate the PC Drum so that the area of its surface on
which the line of toner left by the Cleaning Blade is pres-
entis facing straight up. Wipe the surface in one contin-
uous movement from the rear edge of the PC Drum to
the front edge and off the surface of the PC Drum.
b) Rotate the PC Drum slightly and wipe the newly ex-
posed surface area with a CLEAN face of the Dust-Free
Cotton Pad. Repeat this procedure until the entire sur-
face of the PC Drum has been thoroughly cleaned.
* Atthis 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 asmail amount of either ethyl alcohol or isopropyl al-
cohol 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 ex-
plained 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 tums of the PC Drum
would be appropriate for cleaning.
NOTES
® The Organic Photoconductor Drum is softer than CdS and Selenium Drums and is therefore
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
iflumination.
© if dirt remains after cleaning, repeat the entire procedure from the beginning one more time.
