Toner cartridges having positional control features

A toner cartridge for use in an image forming device, comprising:

• a housing having a reservoir for containing toner therein, the housing having an exit port in fluid communication with the reservoir to permit toner from the reservoir to pass out of the housing;
• a first leg and a second leg each projecting from a bottom portion of the housing and extending between a rear portion and a front portion of the housing parallel to a direction of insertion of the toner cartridge into the image forming device, the first and second legs being spaced from each other on opposite sides of the housing to limit the side-to-side travel of the toner cartridge during insertion into the image forming device;
• a first wing guide positioned on a first side surface of the housing and a second wing guide positioned on a second side surface of the housing substantially parallel to the first wing guide, each wing guide having a generally elongated body that extends between the rear portion and the front portion of the housing;
• a first stop extending from the first wing guide and a second stop extending from the second wing guide to limit the forward travel of the toner cartridge in the image forming device;
• and
• a pair of rounded projections extending from a bottom surface of the first wing guide and a rounded projection extending from a bottom surface of the second wing guide that collectively form three datum points defining a plane that controls the vertical position of the toner cartridge in the image forming device.
