Drum Cleaning And Lubrication - Ricoh D014 Service Manual

6.6.5 DRUM CLEANING AND LUBRICATION

To improve the efficiency of cleaning, the drum is lubricated with ZnSt (Zinc Stearate).
This cleaning sequence is the same in each PCU:
The cleaning brush roller [1] brushes residual toner and other matter from the surface
of the drum.
The cleaning roller flicker [2] combs the cleaning brush roller to remove toner from the
brush.
The cleaning blade [3] (a counter blade) scrapes toner from the drum.
All collected toner falls down into the toner collection coil [4]. This revolving coil moves
the used toner to the used toner port at the back of the PCU.
The lubricant bar [5] supplies lubricant (ZnSt) to the lubricant brush roller [6], and the
lubricant brush roller applies the lubricant to the drum.
Finally, the lubricant blade [7] smoothes the powder lubricant applied to the surface of
the drum by the lubricant brush roller.
