The toner bottle motor turns the toner bottle [A], causing toner to leave the bottle
and drop into the toner entrance tank [B].
NOTE: Recycled toner in the tube from the drum cleaning unit also enters the
toner entrance tank, and is mixed with fresh toner from the toner bottle.
The toner transport coil [C] in the toner transport tube transports toner to the toner
supply cylinder [D]. The toner bank motor [E] drives the toner transport coil via the
toner supply coil clutch [F].
The toner supply pump motor [G] creates the suction needed to draw the toner
from the toner supply and send it to the toner hopper [H].
The toner hopper has two air pressure release filters and an air return tube [I]
connected to the toner supply cylinder. Air returns to the toner supply cylinder from
the toner hopper through the air return tube.
