Toner cartridge having positional control features
View Patent ↗A toner cartridge according to one example embodiment includes a housing that has an elongated shape extending from a first side to a second side. The housing defines a reservoir for containing toner therein. An exit port is in fluid communication with the reservoir and faces downward on the front of the housing near the first side. A first leg portion and a second leg portion each projects from the bottom of the housing and extends along a front-to-rear dimension of the housing. The first leg portion has a first outer side spaced inward from the first side of the housing and the second leg portion has a second outer side spaced inward from the second side of the housing. The first outer side and the second outer side are unobstructed to limit the side-to-side travel of the toner cartridge during insertion into the image forming device.
1. A toner cartridge for use in an image forming device, comprising:
a housing having a top, a bottom, a front, and a rear positioned between a first side and a second side of the housing, the housing having an elongated shape extending from the first side to the second side, the housing defining a reservoir for containing toner therein, the housing including a main housing body, a first end cap attached to the main housing body and forming the first side of the housing, and a second end cap attached to the main housing body and forming the second side of the housing;
an exit port in fluid communication with the reservoir and facing downward on the front of the housing;
a first leg and a second leg each projecting from a bottom of the main housing body and extending along a front-to-rear dimension of the housing, the first leg having a first outer side spaced inward from the first side of the housing and the second leg having a second outer side spaced inward from the second side of the housing, the first outer side and the second outer side being unobstructed by the first end cap and the second end cap, respectively, from a frontmost portion to a rearmost portion of the respective first or second outer side to permit the first outer side and the second outer side to contact corresponding positioning surfaces in the image forming device to limit the side-to-side travel of the toner cartridge during insertion into the image forming device; and
a bottom of the first end cap having a first side bottom surface at the first side of the housing and a bottom of the second end cap having a second side bottom surface at the second side of the housing, the first side bottom surface and the second side bottom surface extending along the front-to-rear dimension of the housing, the first side bottom surface and the second side bottom surface being unobstructed to travel above a first ledge and a second ledge, respectively, when the toner cartridge is installed in the image forming device,
wherein the first leg and the second leg extend lower than the first side bottom surface and the second side bottom surface.
2. The toner cartridge of claim 1 , further comprising an inner bottom surface extending along the front-to-rear dimension of the housing and positioned between the first leg and the second leg, the inner bottom surface curving from the front to the rear of the main housing body, the inner bottom surface extending lower than the first side bottom surface and the second side bottom surface.
3. The toner cartridge of claim 2 , wherein at least a portion of each of the first side bottom surface and the second side bottom surface is flat.
