Abstract
A toner cartridge according to one example embodiment includes a housing having a reservoir for containing toner and an exit port in fluid communication therewith. A movable shutter is positioned at the exit port. A linkage is operatively connected to the shutter to open the shutter upon being actuated by a first engagement feature in the image forming device. The linkage includes a first linkage member positioned to receive the first engagement feature and a second linkage member connected to the shutter. An interlock is operatively engaged with the linkage and biased toward a locked position preventing the second linkage member from opening the shutter but permitting the first linkage member to move relative to the second linkage member. The interlock is movable to an unlocked position upon being actuated by a second engagement feature in the image forming device that permits the second linkage member to open the shutter.
