Abstract
A waste toner system includes a rotatable photoconductive drum and a cleaner member. A first toner sump extends along a length of the photoconductive drum for receiving waste toner removed from the outer surface of the photoconductive drum by the cleaner member. A first rotatable auger extends along the first toner sump. A pass-through opening extends from the first toner sump to a second toner sump. A second rotatable auger extends along the second toner sump. The first auger is positioned to move waste toner in the first toner sump to the pass-through opening upon rotation of the first auger in an operative rotational direction of the first auger and the second auger is positioned to distribute waste toner received through the pass-through opening into the second toner sump upon rotation of the second auger in an operative rotational direction of the second auger.
