  • 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.

  • Publication number: 20150227080
    Abstract: A toner delivery system for a toner cartridge includes a toner paddle assembly having a drive shaft and a frame extending from the drive shaft. A first scraper and a second scraper each extend in their free states in a cantilevered manner from a distal end of the frame in a direction generally orthogonal to the extension of the frame and to an axis of rotation of the drive shaft. The second scraper has a cantilevered length measured along a direction that the second scraper extends in the cantilevered manner from the distal end of the frame that varies along an axial direction of the drive shaft. The first scraper and the second scraper are positioned to have an interference contact with the front of the toner cartridge housing along a first portion and a second portion, respectively, of a channel upon rotation of the drive shaft.
