6.12.7 TONER HOPPER

Toner Supply

[G]
[G]
The toner supply pump motor pumps toner from the toner bottle into the hopper.
(!6.13.3)
When the toner supply roller clutch [A], inside the development motor unit [B], turns
on, the agitator [C] mixes the toner transported by the air tube [G] from the toner
bank (the toner from the toner bank is new toner mixed with recycled toner). Then it
moves the toner from front to rear and sends it to the toner supply roller.
Toner is caught in the grooves in the toner supply roller [F]. Then, as the grooves
turn past the opening, the toner falls into the development unit.
The toner supply roller clutch [A] transfers drive from the development motor to the
toner supply roller gear [D], which drives the agitator gear [E].
Toner supply is controlled by the ID sensor and the toner density sensor. (!6.12.8)
