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. 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.
