Abstract
A toner cartridge for an electrophotographic device including a housing having a reservoir that is in fluid communication with an exit port. A first end wall has a recess on an inner surface thereof in fluid communication with the reservoir and the exit port. A partially threaded drive shaft has an end received in a second end wall. An exit paddle having a drive hub is detachably mounted on the drive shaft near an unthreaded portion. Arms on the drive hub are received in the recess. A drive hub axial extension is received in the first end wall. The housing rotatably supports the drive shaft and exit paddle. A translatable toner platform rotatably connects to the drive shaft. When the drive shaft rotates the toner platform translates, moving toner toward the exit port, and the exit paddle rotates, delivering toner from the exit port.
