Cleaning
Assembly
The transfer drum cleaning assembly is operated following every 100
prints, upon power-on, door-open/close or cleaning of the density
detection pattern after image quality stability control.
The transfer drum cleaner is normally separated from the transfer drum.
After the transfer is completed and the paper is separated, the transfer
drum cleaner press solenoid (SL8) is turned on to actuate the transfer
drum cleaner press cam to press the cleaning brush against the transfer
drum. When the cleaning brush motor (M5) is turned on, the cleaning
brush starts rotating. After this cleaning is completed, SL8 is turned off
to release the cam, and the spring force separates the cleaning brush
from the transfer drum. Simultaneously, the cleaning brush motor is
turned off.
Cleaning brush rotation will not interrupt a multiple-page print job.
