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.

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.

Abstract: A photoconductive member for an image forming apparatus includes a hollow, conductive cylindrical drum; an insulating end cap disposed axially within the drum at either end thereof, each end cap including an axial bore; a shaft disposed axially through the drum and the bores, the shaft electrically isolated from the drum by the end caps; and an electrical contact assembly operative to bias the drum, but not the shaft, to an operating voltage.

Abstract: A toner cartridge included with an image forming device when initially sent to a user. The cartridge has a limited toner capacity. The user is able to print with the small capacity cartridge upon initially receiving the image forming device. Once the toner is exhausted, a second large capacity cartridge having a greater toner capacity can replace the small capacity cartridge. The small capacity cartridge and the large capacity cartridge are constructed in a similar shape to be mounted in the same manner within the image forming device.

Abstract: A device and method of supporting a doctor blade within an image forming apparatus. The device has a housing for positioning a doctor blade such that a bottom edge contacts a developer roller. One or more extensions are positioned to support a first side of the doctor blade. The one or more extensions may include dampeners which are constructed of a resilient material. Supports are positioned on a second side of the doctor blade. The doctor blade is sized to fit between the one or more extensions and the supports. A method of supporting the doctor blade includes positioning the doctor blade to dampen vibrations and velocity fluctuations caused by sticking and slipping of the bottom edge of the doctor blade against the developer roller.
