8. DRUM CLEANING
8.1 OVERVIEW
[D]
[A]
[C]
This copier uses the counter blade system for drum cleaning.
The cleaning blade [A] is angled against drum rotation. This counter blade
system has the following advantages:
•
Less wearing of the cleaning blade edge.
•
High cleaning efficiency.
Due to the high efficiency of this counter blade system, this copier does not
use a cleaning brush.
The removed toner falls into the cleaning unit. The toner collection roller [C]
carries the used toner to the used toner tank. The quenching lamp [D]
neutralizes any charge remaining on the drum in preparation for the next
copy cycle.
The cleaning blade is always in contact with the drum. It releases when the
release knob is pressed. This prevents the drum from being damaged when
the cleaning unit is removed or installed.
