Abstract
A toner cartridge includes a waste bin and hopper designed for the elimination of non-essential parts between the waste bin and the hopper via an enhanced interconnection between the waste bin and the hopper, improved drive dogs and cluster gear assembly to facilitate complete engagement with the printer drive mechanism, an improved door to protect the photoconductive drum from light, and improved electrical contacts between the doctor bar, toner adder roller and developer roller.
