Abstract:
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; and a 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; and 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.
