8. DRUM CLEANING
8.1 OVERVIEW
The cleaning brush [A] and cleaning blade [B] remove any toner remaining
on the drum [C] after the image is transferred to the paper.
The cleaning brush and drum move in opposite directions at their point of
contact. The cleaning brush removes paper dust and nearly half of the toner
from the drum surface to reduce the cleaning load placed on the blade.
The cleaning blade removes the remaining toner. The falling toner catches in
the fibers of the cleaning brush and is carried inside the cleaning unit [D]. The
toner collection roller [E] carries the used toner to the used toner tank. The
light of the quenching lamp [F] neutralizes any charge remaining on the drum
in preparation for the next copy cycle.
