A toner cartridge for use in an image forming device according to one example embodiment includes a housing having a reservoir for containing toner therein. The housing has an exit port in fluid communication with the reservoir. A cover is mounted on an exterior portion of the housing that is pivotable between a closed position blocking the exit port and an open position unblocking the exit port. The cover is biased toward the closed position. An actuation mechanism is operatively connected to the cover to open the cover upon being actuated by an engagement feature in the image forming device.

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 in fluid communication with the reservoir;a cover pivotable between a closed position blocking the exit port and an open position unblocking
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 in fluid communication with the reservoir;a cover pivotable between a closed position blocking the exit port and an open position unblocking the exit port, the cover being biased toward the closed position; andan actuation mechanism operatively connected to the cover to open the cover upon being actuated by an engagement feature in the image forming device,wherein the cover blocks an outer portion of the exit port when the cover is in the closed position; and as the cover moves from the closed position to the open position, the cover moves away from the outer portion of the exit port outside of the housing. 2. The toner cartridge of claim 1, further comprising a foam member on an inner face of the cover to soak up residual toner. 3. The toner cartridge of claim 1, further comprising a slot in a front portion of the housing that allows the engagement feature to contact the actuation mechanism at a position closer to a bottom of the housing than the exit port and spaced from the exit port toward a side wall of the housing nearest the exit port as the toner cartridge is inserted in the image forming device. 4. The toner cartridge of claim 1, wherein the actuation mechanism includes a linkage member pivotally attached to a side wall of the housing and the linkage member is operatively connected to the cover such that rotation of the linkage member causes the cover to move between the open and closed positions. 5. The toner cartridge of claim 4, further comprising a link that connects the linkage member to the cover such that rotation of the linkage member raises or lowers the link causing the cover to move between the open and closed positions. 6. The toner cartridge of claim 5, further comprising an elongated slot in the link that receives a post extending from the cover, the width of the slot being greater than a diameter of the post such that the post is free to float within the slot. 7. The toner cartridge of claim 1, further comprising 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. 8. The toner cartridge of claim 1, wherein when the cover is in the open position, the cover is positioned closer to a bottom of the housing than the exit port. 9. The toner cartridge of claim 8, further comprising a recess on an exterior portion of the housing positioned closer to the bottom of the housing than the exit port that receives the cover when the cover is in the open position. 10. A toner cartridge for use in an image forming device having an imaging unit separate from the toner cartridge removably installed therein, the imaging unit including a developer unit, the toner cartridge comprising: a housing having a reservoir for containing toner therein;an exit port on a front portion of the housing in fluid communication with the reservoir;a cover pivotable between a closed position where the cover is pressed against an outer portion of the exit port to trap residual toner and an open position where the cover is pivoted away from the outer portion of the exit port outside of the housing to expose the exit port, the cover being biased toward the closed position;a foam member on an inner face of the cover to soak up residual toner; andan actuation mechanism attached to the housing and operatively connected to the cover,wherein when the toner cartridge is inserted in the image forming device, an engagement feature on the imaging unit engages the actuation mechanism causing the cover to pivot from the closed position to the open position. 11. The toner cartridge of claim 10, further comprising a slot in the front portion of the housing that allows the engagement feature to contact the actuation mechanism at a position closer to a bottom of the housing than the exit port and spaced from the exit port toward a side wall of the housing nearest the exit port as the toner cartridge is inserted in the image forming device. 12. The toner cartridge of claim 10, wherein the actuation mechanism includes a linkage member pivotally attached to a side wall of the housing and operatively connected to the cover; and when the toner cartridge is inserted in the image forming device, the engagement feature on the imaging unit causes the linkage member to rotate and open the cover. 13. The toner cartridge of claim 12, further comprising a link that connects the linkage member to the cover, wherein when the toner cartridge is inserted in the image forming device, the rotation of the linkage member raises or lowers the link to open the cover. 14. The toner cartridge of claim 13, further comprising an elongated slot in the link that receives a post extending from the cover, the width of the slot being greater than a diameter of the post such that the post is free to float within the slot. 15. The toner cartridge of claim 10, wherein when the toner cartridge is in its final position in the image forming device and the cover is in the open position, the cover is positioned outside of the housing closer to a bottom of the housing than the exit port and the cover is not biased against the developer unit. 16. The toner cartridge of claim 10, wherein when the cover is in the open position, the cover is positioned closer to a bottom of the housing than the exit port. 17. The toner cartridge of claim 16, further comprising a recess on the front portion of the housing positioned closer to the bottom of the housing than the exit port that receives the cover when the cover is in the open position. 18. A toner cartridge for use in an image forming device, comprising: a housing having a reservoir for containing toner therein;an exit port on a front portion of the housing in fluid communication with the reservoir for exiting toner from the reservoir;a cover pivotable between a closed position where a sealing face of the cover is pressed against an outer portion of the exit port to trap residual toner and an open position where the cover is pivoted away from the outer portion of the exit port with the sealing face of the cover positioned on an exterior of the cartridge facing away from the front portion of the housing, the cover being biased toward the closed position; andan actuation mechanism operatively connected to the cover to open the cover upon being actuated by an engagement feature in the image forming device. 19. The toner cartridge of claim 18, wherein when the cover is in the open position, the cover is positioned closer to a bottom of the housing than the exit port.
