This machine uses dual-component development with toner concentration control
(.Photocopying Processes – Development – Dual-component Development).
The toner agitator [A] turns in the center of the toner cartridge to move toner to the
paddle roller [B] in the development unit. Toner then goes to the development roller
[C] and the drum [D].To control the quantity of toner that is supplied to the
development unit, the machine switches the toner supply clutch on and off. The
output from the ID sensor controls the clutch on/off timing. This development unit
does not have a TD sensor.
