An example toner cartridge includes a reservoir for containing toner and an exit port in fluid communication with the reservoir. A shutter is positioned at the exit port and movable between an open position and a closed position. A first linkage member is operatively connected to the shutter to open the shutter upon being actuated by a first engagement feature. A second linkage member is pivotally attached to a side wall of the housing and biased toward a home position. A third linkage member is movable with the second linkage member. When the second linkage member is in the home position, the third linkage member is in a blocking position preventing the first linkage member from opening the shutter. When the second linkage member pivots away from the home position, the third linkage member moves to a non-blocking position permitting the first linkage member to open the shutter.

1. A toner cartridge for use in an image forming device, 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 first linkage member operatively connected to the shutter to open the shutter upon being actuated by a first engagement feature in the image forming device, the first linkage member having a first engagement surface positioned on a rear portion of the housing to contact the first engagement feature to open the shutter;a second linkage member pivotally attached to a side wall of the housing and biased toward a home position, the second linkage member having a second engagement surface positioned on the front portion of the housing to contact a second engagement feature to pivot the second linkage member away from the home position; anda third linkage member movable with the second linkage member,wherein when the second linkage member is in the home position, the third linkage member is in a blocking position preventing the first linkage member from opening the shutter and when the second linkage member pivots away from the home position, the third linkage member moves to a non-blocking position permitting the first linkage member to open the shutter upon being actuated by the first engagement feature,further comprising a catch on the first linkage member that engages with the third linkage member when the first linkage member is actuated by the first engagement feature and the third linkage member is in the blocking position; anda flexible damping arm extending in front of the catch and positioned to contact the third linkage member and deflect backward when the first linkage member is actuated by the first engagement feature and the third linkage member is in the blocking position. 2. The toner cartridge of claim 1, further comprising a knob extending from the third linkage member positioned in a path of movement of the catch of the first linkage member when the third linkage member is in the blocking position. 3. The toner cartridge of claim 2, wherein the catch extends from a bottom portion of the first linkage member and the knob extends from a side portion of the third linkage member. 4. The toner cartridge of claim 1, wherein the first engagement surface is positioned on a first end of the first linkage member and a second end of the first linkage member is operatively connected to the shutter through a lever. 5. The toner cartridge of claim 1, further comprising a slot in the front portion of the housing that allows the second engagement feature to contact the second engagement surface as the toner cartridge is inserted in the image forming device. 6. The toner cartridge of claim 1, further comprising a cover mounted on an exterior portion of the housing pivotable between a closed position covering the exit port and an open position uncovering the exit port, the cover being operatively connected to the third linkage member such that when the third linkage member is in the blocking position, the cover is in the closed position and when the third linkage member moves to the non-blocking position, the cover moves to the open position. 7. The toner cartridge of claim 6, further comprising a channel in the third linkage member that receives a post extending from the cover. 8. A toner cartridge for use in an image forming device, 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 cover mounted on an exterior portion of the housing pivotable between a closed position covering the exit port and an open position uncovering the exit port, the cover being biased toward the closed position;a first linkage member operatively connected to the shutter to open the shutter upon being actuated by a first engagement feature in the image forming device, the first linkage member having a first engagement surface positioned on a rear portion of the housing to contact the first engagement feature to open the shutter;a second linkage member pivotally attached to a side wall of the housing and biased toward a home position, the second linkage member having a second engagement surface positioned on the front portion of the housing to contact a second engagement feature to pivot the second linkage member away from the home position; anda third linkage member movable with the second linkage member and operatively connected to the cover such that when the second linkage member is in the home position, the cover is in the closed position and when the second linkage member pivots away from the home position, the third linkage member moves the cover to the open position,wherein when the second linkage member is in the home position, the third linkage member is in a blocking position preventing the first linkage member from opening the shutter and when the second linkage member pivots away from the home position, the third linkage member moves to a non-blocking position permitting the first linkage member to open the shutter upon being actuated by the first engagement feature. 9. The toner cartridge of claim 8, further comprising a catch on the first linkage member that engages with the third linkage member when the first linkage member is actuated by the first engagement feature and the third linkage member is in the blocking position. 10. The toner cartridge of claim 9, further comprising a flexible damping arm extending in front of the catch and positioned to contact the third linkage member and deflect backward when the first linkage member is actuated by the first engagement feature and the third linkage member is in the blocking position. 11. The toner cartridge of claim 9, further comprising a knob extending from the third linkage member positioned in a path of movement of the catch of the first linkage member when the third linkage member is in the blocking position. 12. The toner cartridge of claim 11, wherein the catch extends from a bottom portion of the first linkage member and the knob extends from a side portion of the third linkage member. 13. The toner cartridge of claim 8, wherein the first engagement surface is positioned on a first end of the first linkage member and a second end of the first linkage member is operatively connected to the shutter through a lever. 14. The toner cartridge of claim 8, further comprising a slot in the front portion of the housing that allows the second engagement feature to contact the second engagement surface as the toner cartridge is inserted in the image forming device. 15. The toner cartridge of claim 8, further comprising a channel in the third linkage member that receives a post extending from the cover.
