Abstract
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.
