Abstract:
An apparatus for moving waste toner within a printer cartridge includes an auger having a radially inward facing surface, the radially inward facing surface defining an opening having an inner diameter. An elongated drive shaft has an outer surface defining an outer diameter, the outer diameter of the drive shaft being greater than the inner diameter of the auger. The radially inward facing surface of the auger engages the outer surface of the drive shaft with a first pressure when the drive shaft is rotated within the opening of the auger in a first direction with a first load applied on the auger.
