6.12.7 TONER HOPPER
Toner Supply
The toner supply pump motor pumps toner from the toner supply cylinder into the
hopper (6.13). This toner is new toner mixed with recycled toner.
When the hopper agitator motor [A] (inside the development motor unit [B]) turns
on, the agitator [C] mixes the toner. Then it moves the toner from rear to front and
sends it to the toner supply roller.
Toner is caught in the grooves in the toner supply roller [D]. Then, as the grooves
turn past the opening, the toner falls into the development unit.
The toner supply motor [E] drives the toner supply roller.
Toner supply is controlled by the ID sensor and the toner density sensor. (6.12.8)
