Waste Toner Collection
G133 6-38 SM
used toner to the opening [D] at the rear of the toner collection bottle. The toner transport
motor [E] drives the toner collection coil.
Used Toner Distribution Mechanism
The toner collection bottle has two openings (front and rear). The opening at the front is for
the toner from the PCUs, and the opening at the rear is for the toner from the image
transfer belt.
To distribute the toner inside the bottle evenly, the auger [A] moves the toner to the center
area. The mixing auger has two spirals in different directions. As a result, it is possible to
gather the toner in the center area of the toner collection bottle even if the mixing auger
always rotates in the same direction. The toner transport motor [B] drives the mixing auger
via a timing belt and gears.
6.6.2 TONER COLLECTION BOTTLE SET/ NEAR-FULL/ FULL
DETECTION
The toner collection bottle has a projection at its rear side. When the toner collection bottle
is set, this projection pushes the waste toner bottle set switch at the rear of the machine. As
a result, the machine detects that the toner collection bottle is installed.
The bottle near-full/full detection mechanism is above the bottle. When the used toner
pushes up the used toner feeler [A], the waste toner sensor [B] turns off
