This machine uses the dual component development method with toner
concentration control !.
The paddle roller picks up developer in its paddles and transports it to the
development roller. Internal permanent magnets in the development roller attract
the developer to the development roller sleeve.
The rotation of the sleeve carries developer toward the OPC drum. Developer back
spill from the doctor blade goes either to the separator then the agitator, or to the
augur then the paddle roller.
A filter relieves the pressure that tends to build up in the development unit.
The toner density is constantly monitored by an ID sensor (there is no TD sensor).
