Toner cartridges having positional control features

摘要

A toner cartridge for use in an image forming device according to one example embodiment includes a housing having a reservoir for containing toner therein. The housing has 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 project from a bottom portion of the housing to limit the side-to-side travel of the toner cartridge during insertion into the image forming device. Wing guides are positioned on opposite side surfaces of the housing. A stop extends from each wing guide to limit the forward travel of the toner cartridge in the image forming device. Rounded projections extending from the bottom surfaces of the wing guides define contact points to control the vertical position of the toner cartridge in the image forming device.

1. 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 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; 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 define contact points to control the vertical position of the toner cartridge in the image forming device; and a slot on the front portion of the housing between the first and second legs that is sized to receive a corresponding projection in the image forming device to more finely control the side-to-side travel of the toner cartridge in the image forming device.
