TONER CARTRIDGE HAVING POSITIONAL CONTROL FEATURES

A toner cartridge for use in an electrophotographic image forming device has a housing with a reservoir for holding toner, an outlet port and a toner delivery system with a main input gear. A first alignment guide extends outward from the second side of the housing and runs along a front-to-rear dimension of the housing. A second alignment guide and a third alignment guide extend outward from the first side of the housing with the second alignment guide being spaced toward the front of the housing from the third alignment guide. A fourth alignment guide extends outward from the first side of the housing and the fourth alignment guide includes a front surface and a top surface to provide a forward stop and to provide an upward rotational stop when the toner cartridge is installed in the image forming device. The first, second and third alignment guides include bottom surfaces that are unobstructed to sit on top of corresponding guide surfaces in the image forming device to control a vertical position of the toner cartridge when the toner cartridge is installed in the image forming device.
