8.1 DRUM CLEANING
8.1.1 Overview
[D]
[A]
[B]
[C]
The cleaning blade [A] removes any toner remaining on the drum [B] after the
image is transferred to the paper.
The removed toner falls into the cleaning unit. The toner collection roller [C]
carries the used toner to the used toner tank. The light of the quenching lamp
[D] neutralizes any charge remaining on the drum in preparation for the next
copy cycle.
The cleaning blade releases when the release knob is pressed. This prevents
the drum from being damaged when the cleaning unit is removed or installed.
