Abstract

A toner cartridge according to one example embodiment includes a housing having a toner reservoir. An outlet is positioned on the housing for exiting toner from the toner cartridge. An insert is selectably installable in the toner reservoir. The insert separates a first portion of the toner reservoir that is in fluid communication with the outlet from a remainder of the toner reservoir when the insert is installed in the toner reservoir providing a reduced capacity toner reservoir in the first portion of the toner reservoir.

Claims (10)

1. A toner cartridge, comprising:

a housing having a toner reservoir;

an outlet on the housing for exiting toner from the toner cartridge;

a rotatable auger operative to deliver toner from the toner reservoir to the outlet; and

a divider that isolates a volume of the toner reservoir surrounding the auger that is in fluid communication with the outlet from a remainder of the toner reservoir such that the divider forms a reduced capacity toner reservoir surrounding the auger,

wherein the divider is wrapped under the auger along a length of the auger.

2. The toner cartridge of claim 1 , wherein the reduced capacity toner reservoir surrounding the auger is sealed from the remainder of the toner reservoir.

3. The toner cartridge of claim 1 , wherein a volume of the reduced capacity toner reservoir is smaller than a volume of the remainder of the toner reservoir.
