More Information
Summary:A waste toner removal device for transporting toner from a photoconductive drum within an image-forming apparatus. The invention includes a waste toner reservoir having outer walls forming an interior chamber for housing toner removed from the photoconductive drum. An opening is positioned within the outer walls into the interior chamber forming an upper chamber section extending above the opening and a lower chamber section extending below the opening. An auger extends along the photoconductive drum and unobstructed into the opening of the waste toner reservoir. The auger includes helical blades extending outward for moving the toner from the photoconductive drum into the waste toner reservoir. A pumping cylinder having a generally cylindrical shape extends around the auger adjacent to the waste toner reservoir. The diameter of the pumping cylinder is approximately equal to the helical blades wherein rotation of the auger creates a pumping action for moving toner into the said upper and lower chamber sections.
