Do not rotate the magnet roller during work. Otherwise, waste toner may fall throught the cleaner assembly.
1) Remove the process unit.
2) Remove the photosensitive drum.
3) Moisten lint-free paper [1] with 5 to 10 cc of alcohol solutions [2]; then, pour 0.2 to 0.3 g of the drum cleaning powder (CK-0429) [3] on the lint-free paper.
4) While butting the lint-free paper relatively strongly against the photosensitive 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) After the alcohol has evaporated, dry wipe the surface with the lint-free paper. If the area is uneven, go back to the step 4, and increase the back-and-forth move-
ments.
6) Rotate the drum for the width (5 to 10 cm), and repeat the step 3 through 5 until the entire area of the surface has been cleaned.
