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.

1. A toner cartridge for use in an image forming device having an imaging unit separate from the toner cartridge removably installed therein, the toner cartridge comprising: a housing having a reservoir for containing toner therein, the housing having an exit port on a front portion of the housing in fluid communication with the reservoir;a shutter positioned at the exit port that is movable between an open position to permit toner from the reservoir to pass out of the exit port and a closed position to prevent toner from passing out of the exit port, the shutter being biased toward the closed position;a linkage operatively connected to the shutter to open the shutter upon being actuated by an engagement feature on the image forming device, the linkage including a first linkage member and a second linkage member, a first end of the first linkage member including a first engagement surface exposed to an exterior of a rear portion of the housing to receive the engagement feature on the image forming device, a second end of the first linkage member overlapping with a first end of the second linkage member, and a second end of the second linkage member being connected to the shutter; anda rotatable interlock member pivotally attached to a side wall of the housing, the rotatable interlock member having: a first leg extending radially from a pivot axis of the rotatable interlock member and operatively engaged with the second linkage member; anda second leg extending radially from the pivot axis of the rotatable interlock member, the second leg including a second engagement surface exposed to an exterior of the front portion of the housing to receive an engagement feature on the imaging unit,wherein the rotatable interlock member is rotatable between a locked position and an unlocked position and biased toward the locked position, when the rotatable member is in the locked position the second linkage member is clear of a catch on the first linkage member so that the first linkage member is free to move relative to the second linkage member upon actuation of the first linkage member by the engagement feature on the image forming device without opening the shutter, and when the rotatable interlock member is rotated from the locked position to the unlocked position upon being actuated by the engagement feature on the imaging unit the first leg of the rotatable interlock member raises the second linkage member into the path of the catch on the first linkage member so that actuation of the first linkage member by the engagement feature on the image forming device causes the first linkage member to engage the second linkage member causing the second linkage member to move with the first linkage member to open the shutter. 2. The toner cartridge of claim 1, wherein an overlapping portion of one of the first linkage member and the second linkage member is positioned between a pair of side walls of the other of the first linkage member and the second linkage member. 3. The toner cartridge of claim 1, further comprising a slot in the front portion of the housing that allows the engagement feature on the imaging unit to contact the second engagement surface as the toner cartridge is inserted in the image forming device. 4. The toner cartridge of claim 1, wherein the second leg of the rotatable interlock member includes a first portion that extends radially from the pivot axis of the rotatable interlock member and a second portion that extends in a curved manner from the first portion and the second engagement surface is positioned on the second portion of the second leg. 5. The toner cartridge of claim 1, wherein the first leg includes a flexible member at a distal end of the first leg that includes a curved outer surface that supports a bottom surface of the second linkage member as the second linkage member moves. 6. A toner cartridge for use in an image forming device having an imaging unit separate from the toner cartridge removably installed therein, the toner cartridge comprising: a housing having a reservoir for containing toner therein, the housing having an exit port on a front portion of the housing in fluid communication with the reservoir;a shutter positioned at the exit port that is movable between an open position to permit toner from the reservoir to pass out of the exit port and a closed position to prevent toner from passing out of the exit port, the shutter being biased toward the closed position;a linkage operatively connected to the shutter to open the shutter upon being actuated by an engagement feature on the image forming device, the linkage including a first linkage member and a second linkage member, a first end of the first linkage member including a first engagement surface exposed to an exterior of a rear portion of the housing to receive the engagement feature on the image forming device, a second end of the first linkage member overlapping with a first end of the second linkage member, and a second end of the second linkage member being connected to the shutter; anda rotatable interlock member pivotally attached to a side wall of the housing at a first end of the rotatable interlock member, the rotatable interlock member having an elongated body that extends from a pivot axis of the rotatable interlock member toward the front portion of the housing and a second end that includes a second engagement surface exposed to an exterior of the front portion of the housing to receive an engagement feature on the imaging unit,wherein the rotatable interlock member is rotatable between a locked position and an unlocked position and biased toward the locked position, when the rotatable member is in the locked position the second linkage member is clear of a catch on the first linkage member so that the first linkage member is free to move relative to the second linkage member upon actuation of the first linkage member by the engagement feature on the image forming device without opening the shutter, and when the rotatable interlock member is rotated from the locked position to the unlocked position upon being actuated by the engagement feature on the imaging unit the rotatable interlock member raises the second linkage member into the path of the catch on the first linkage member so that actuation of the first linkage member by the engagement feature on the image forming device causes the first linkage member to engage the second linkage member causing the second linkage member to move with the first linkage member to open the shutter. 7. The toner cartridge of claim 6, wherein an overlapping portion of one of the first linkage member and the second linkage member is positioned between a pair of side walls of the other of the first linkage member and the second linkage member. 8. The toner cartridge of claim 6, further comprising a slot in the front portion of the housing that allows the engagement feature on the imaging unit to contact the second engagement surface as the toner cartridge is inserted in the image forming device. 9. The toner cartridge of claim 6, further comprising a post extending upward from the rotatable interlock member that contacts and raises the second linkage member into the path of the catch on the first linkage member when the rotatable interlock member rotates from the locked position to the unlocked position.
