An ID sensor pattern is made during machine initialization (after the main power
switch is turned on) and after 10 sheets are printed out.
2.4.4 DRUM CHARGE ROLLER CLEANING
[B]
[A]
The drum charge roller [A] gets dirty easily because it is always in contact with the
drum. Therefore, the cleaning pad [B] is also always in contact with the drum
charge roller to clean its surface.
The cam gear [D] moves the pin [C] at the rear of the cleaning pad holder, and also
moves the cleaning pad from side to side. This movement improves the cleaning
process.
