1.3 Cleaning the photosensitive drum
Do not rotate the magnet roll
during work. Otherwise, waste
toner may fall through the
cleaner assembly.
1) Slide out the process unit. (Be sure to
place the drum protective sheet over the
fixing/feeding unit.)
2) Take out the photosensitive drum.
3) Moisten lint-free paper [1] with 5 to 10
cc of alcohol [2]; then, pour 0.2 to 0.3 g
of drum cleaning powder (CK-0429) [3]
on the lint-free paper.
4) While butting the lint-free paper rela-
tively strongly against the photosensi-
tive drum, wipe the surface of the drum
from the front to the rear and from the
rear to the front.

• Keep the widths of cleaning to
5 to 10 cm in the peripheral
direction of the drum.
• Move the lint-free paper back
and forth 15 to 20 times over a
single area.
Forcing the lint-free paper will
not affect the life of the drum.
5) When the alcohol has evaporated, dry
wipe the surface with lint-free paper. If
the area is uneven, go back to step 4),
and increase the back-and-forth move-
ments.
6) Rotate the drum for the width (5 to 10
cm), and repeat steps 3) through 5) until
the entire area of the surface has been
cleaned.
