Abstract
A toner cartridge with a uni-body construction reduces the cost of production as well as reducing the chance of failure during use. The toner cartridge includes a waste bin having a leading end that can be sculpted to mate with the cartridge-receiving cavities of a large number of printers. Additional improvements include an improved toner beater and sensing apparatus, the elimination of a pivotal motion between the elements of the cartridge, an enhanced method of determining the amount of toner remaining in the toner chamber, and an improved means of agitating the toner within the toner chamber.
