  • Patent number: 10048623
    Abstract: A toner cartridge according to one example embodiment includes a housing having a reservoir for containing toner therein. An exit port in fluid communication with the reservoir faces downward on a front of the housing near a first side of the housing. A portion of a main interface gear for providing rotational power to a toner delivery system is exposed on the front of the housing near a top of a second side of the housing and engagable with a corresponding drive gear in the image forming device. A projection projects from the front of the housing and is spaced from the exit port toward the first side of the housing. The projection extends further forward than a frontmost portion of the exit port. A front of the projection is unobstructed for engaging a shutter on a developer unit when the toner cartridge is inserted into the image forming device.

  • Patent number: 9921522
    Abstract: An electrophotographic image forming device according to one example embodiment includes a toner cartridge having a housing that defines a reservoir for containing toner. An exit port in fluid communication with the reservoir faces downward on the front of the housing near a first side. A toner delivery system for transferring toner from the reservoir includes a main interface gear exposed on the front of the housing near the top of the second side. A rearward facing opening is exposed at the rear of the housing near the first side of the housing for receiving a first engagement feature in an image forming device. A forward facing opening is exposed at the front of the housing near the first side of the housing for receiving a second engagement feature in the image forming device. The forward facing opening overlaps with the rearward facing in a side-to-side dimension of the housing.

  • Patent number: 9417603
    Abstract: A toner cartridge for 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 on a front of the housing in fluid communication with the reservoir. A first leg and a second leg each project from a bottom of the housing and extend primarily along a front-to-rear dimension of the housing. A first alignment guide is positioned on a first side of the housing and a second alignment guide is positioned on a second side of the housing. Each alignment guide extends primarily along the front-to-rear dimension of the housing. The first alignment guide includes a pair of rounded contact points and the second alignment guide includes a rounded contact point. The rounded contact points of the first and second alignment control the vertical position of the toner cartridge in the image forming device.

  • Patent number: 8867966
    Abstract: A toner cartridge according to one example embodiment includes a housing that defines a reservoir for containing toner. An exit port in fluid communication with the reservoir faces downward on the front of the housing near a first side. A shutter positioned at the exit port is movable between an open position and a closed position. A toner delivery system for transferring toner from the reservoir includes a main interface gear exposed on the front of the housing near the top of the second side. A rearward facing opening is positioned near the first side of the housing for receiving a first engagement feature in an image forming device for opening and closing the shutter. A forward facing slot is positioned near the first side of the housing for receiving a second engagement feature in the image forming device for locking and unlocking the shutter.

  • Patent number: 8867970
    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 to permit toner from the reservoir to pass out of the housing. A first leg and a second leg each project from a bottom portion of the housing to limit the side-to-side travel of the toner cartridge during insertion into the image forming device. Wing guides are positioned on opposite side surfaces of the housing. A stop extends from each wing guide to limit the forward travel of the toner cartridge in the image forming device. Rounded projections extending from the bottom surfaces of the wing guides define contact points to control the vertical position of the toner cartridge in the image forming device.
