Abstract
A toner cartridge dispenses toner for a printing apparatus. The cartridge comprises a housing having an internal cavity and a series of openings through a sidewall of the housing. An axially reciprocating slide includes a series of openings that are selectively aligned with the housing openings to discharge toner from the cavity. An agitating mechanism operates within the cavity and in response to paper advancement through the printing apparatus to facilitate discharge of toner from the cartridge.
