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.

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.

Abstract: A toner delivery system for a shake-free toner cartridge comprises a toner paddle assembly having a plurality of scrapers. A main scraper scrapes toner adhering to interior surfaces and directs toner from a first region of the toner reservoir into the opening in a first portion of the front of the housing. A secondary scraper positioned adjacent with the main scraper scrapes and directs toner from a second region of the toner reservoir into the first region. A side scraper scrapes toner adhering to interior surfaces of respective side walls of the housing.

Abstract: A toner cartridge for use in an imaging device according to one example embodiment includes a housing having a reservoir enclosed therein for holding a quantity of toner. The housing has an exit port in communication with the reservoir for exiting toner from the toner cartridge. A shutter is mounted on the housing and has a toner path through the shutter. The toner path includes an exit opening. The shutter is moveable between a closed position where the toner path is closed to the exit port preventing toner from exiting the toner cartridge and an open position where the exit opening is open to the exit port allowing toner to exit the toner cartridge. The shutter has an air duct therethrough separated from the toner path. The air duct has a first end in fluid communication with the exit port when the shutter is in the open position.
