Abstract
A toner cartridge according to one example includes a housing having a toner reservoir, an exit for exiting toner and an entry port for receiving waste toner. A partition divides the reservoir into a first compartment for storing fresh toner and a second compartment for storing waste toner. The first compartment is in fluid communication with the exit. The partition is movable within the reservoir between a first position and a second position. The entry port is in fluid communication with the first compartment when the partition is in the first position such that waste toner received through the entry port is deposited into the first compartment. The entry port is in fluid communication with the second compartment but closed off from the first compartment when the partition is in the second position such that waste toner received through the entry port is deposited into the second compartment.
