  • Toner cartridge having a shutter lock mechanism
    Patent number: 9031451
    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.

  • Movable toner port cover member for a replaceable unit of an imaging device
    Patent number: 8867968
    Abstract: A rotating cover on the developer unit of an imaging apparatus to prevent toner leaks from the toner entry port of the developer unit. When installing a toner cartridge, the cartridge contacts a surface to cause the cover to rotate to an open position, thereby exposing the toner port for receiving toner. Conversely, when the toner cartridge is removed the cover is rotated into a closed position with the aid of a torsion spring so as to seal the toner entry port of the developer unit.

  • Toner cartridge having a pivoting exit port cover
    Patent number: 8774684
    Abstract: 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. The cover has a projection extending therefrom such that a force on the projection causes the cover to move toward the open position.
