Dusting The Drum Surface - Ricoh D131 Service Manual


To avoid fingerprints on the surface of the OPC drum, never touch the surface of the
drum with bare fingers.

Never use alcohol to clean the surface of the OPC drum. Blow dry the OPC drum,
then wipe clean with a clean, slightly damp cloth.

Before installing a new drum, dust the surface of the OPC drum carefully with setting
powder. (See below.)

Dusting the Drum Surface


The surface of a new drum is less smooth, so you must apply Drum Setting Powder (P/N:
54429101) to the drum surface before installation.

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.

If setting powder is not available, use waste toner instead of drum setting powder.
However, this could cause dirty backgrounds on the first copies.
