Toner Supply

The toner path is the same for all models. There are two sources of toner: new
toner and recycled toner.
A shutter is pushed open by the PCU body when a toner bottle is set in the
machine. The toner bottle cap is held with a chuck. The cap comes off when you
push in the lever.
Spiral grooves move toner out of the bottle. Mylar blades (circled in red) move
toner through a slit into the development unit. This happens when the clutch
turns the toner bottle.
The toner collection coil recycles toner it gets from the OPC drum. Recycled
toner moves down the chute and goes into the development unit through a slit.
