Note 2: Procedure required BEFORE re-installing the drum cleaning unit
1. If clumps of lubricant (as shown in the photo above) are observed on the drum
surface, gently wipe off with dry cloth. Remaining clumps of lubricant could get
caught between the cleaning blade and drum surface, causing incomplete cleaning
and streaks on the printouts.
DO NOT use a vacuum cleaner. DO NOT strongly wipe the drum surface.
2. If the cleaning unit and drum are both replaced, apply lubricant powder (B1329700)
on the drum surface as described in the service manual in the section:
Replacement and Adjustments > Photoconductor Development Unit (PCDU) >
Drum Replacement > Installing a New Drum
3. Apply lubricant powder (D0159501) on the edges of the cleaning unit as explained in
RTB # RD074071.
