Toner Supply:
The agitator mixes toner and sends it to the toner supply roller and development roller.
Toner End:
The toner detection feeler [4] detects toner end. The toner end sensor is on the outside of the development unit.
Development Unit:
This machine uses a one-roller development system. The high voltage supply applies approximately -300V to the development roller.
This machine does not use a TD sensor or ID sensor to control toner density. The scraper controls the toner density.
