DRUM UNIT 15 February 2006
3-38
Dusting the Drum Surface
The surface of the drum is less smooth, so you must apply Drum Setting Powder
(P/N: 54429101) to the drum surface before installation.
Important!: Failure to apply the drum powder before installation could damage the
drum cleaning blade or scour the drum surface.
1. Apply the setting powder by tapping the powder bag [A] across the surface of
the drum [B].
2. Cover the entire length of the drum over a 45-90 degree portion [C] (about 1/4
of the total drum surface). Apply enough powder so the area turns white.
NOTE: If setting powder is not available, use waste toner instead of drum
setting powder. However, this could cause dirty backgrounds on the
first copies.
3. Install the new drum in the OPC unit so that the powdered surface [D] faces the
cleaning blade [E].
4. Rotate the drum once clockwise [F] until it stops again at the same position.
Important: Never rotate the drum anti-clockwise.
