Part 2>Chapter 5>10.1.5 “Cleaning the Primary Charging Roller ”

The machine’s primary charging roller is cleaned by turning on the primary charging roller cleaning solenoid (SL6) while the primary charging roller is rotating, thereby butting the cleaning pad against the primary charging roller. At the same time, the cleaning pad is moved back and forth in the axial direction of the primary charging roller.

Cleaning is executed under the following conditions:

•During last rotation after the cumulative count reaches 500 sheets

•During execution of roller cleaning in user mode (‘adjust/clean’; in this case, the clean- ing bias is applied to the transfer charging roller pad for cleaning)
