Toner Distribution in the Waste Toner Bottle
Toner Transport
Motor
The two coils in the bottle distribute the toner evenly inside the
toner collection bottle. This ensures that toner does not pile up
at the ends of the bottle.
•
The toner transport motor drives the coils.
This is necessary because the waste toner from the PCUs comes
in at one end of the bottle and the waste toner from the transfer
belt comes in at the other end.
The coils pull the toner in from the ends of the bottle and move it to the center.
This makes sure that toner does not pile up at the ends of the bottle.
The toner transport motor is a very busy motor.
