Theory of Operation
Development
Toner is electrically attached to the invisible electrostatic latent image on the
drum surface to form the visible toner image on the Drum.
The toner in the Toner Cartridge is agitated by the built-in Agitator and fed into
the Developer. The Augers are driven by the Toner Motor and the Developer
Motor in the Main Drive. The toner to be consumed according to the print
count is calculated and fed into the Developer. This process, called Toner
Dispensation, is controlled by two processes: Pixel Count Dispense Control
(PCDC) and Automatic Density Control (ADC).
The toner fed into the Developer and the carrier in the Developer are agitated
by the Auger, and supplied to the Magnet Roller arranged in the drum surface
area. The toner and carrier are charged by friction due to agitation (toner in
negative, carrier in positive), and they are attracted electrically. A uniform
layer is formed by the Trimmer Bar as the carrier magnetic substance is
attracted to the Magnetic Roller.
