When the toner supply motor [A] energizes, the toner supply drive gear [B]
starts turning and drives the toner supply roller gear [C]. Toner catches in the
grooves on the toner supply roller [D]. Then, as the grooves turn past the pin
hole plate [E], the toner drops into the development unit through the pin holes.
The toner agitator [F] mechanism, which is contained in the toner cartridge,
prevents toner from clumping. The toner agitator gear [G] turns whenever the
toner supply motor energizes. Rotation passes through the toner cartridge
casing to the agitator junction [H].
