Abstract
A conveyor mechanism for moving waste toner within an interior of a waste toner reservoir. The conveyor mechanism has a first end positioned in proximity to an inlet into the waste toner reservoir, and a second end positioned vertically above the first end. The conveyor mechanism operates to move the toner from a lower position within the waste toner reservoir to the vertically elevated position. The conveyor device may allow for the capacity of the waste toner reservoir to be more fully utilized. In use, the conveyor device is activated and waste toner is moved into the upper reaches of the waste toner reservoir.
