Claim:
An apparatus for moving toner within an electrophotographic printer, comprising: an auger having a length extending between two ends and having a radially inward facing surface, the radially inward facing surface defining an opening having an inner diameter, the opening extending along at least a portion of the length of the auger; and a drive shaft having an outer surface, the outer surface having an outer diameter, the outer diameter of the drive shaft being greater than the inner diameter of the auger when disengaged from the auger, wherein 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 to the drive shaft; and wherein the drive shaft has a proximal end portion and a distal end portion formed opposite to the proximal end portion, the distal end of the drive shaft having a stopping member disposed thereon to engage a rearward facing surface of the auger when the drive shaft is rotated in the first direction and a second direction.
