Toner container having a common input gear for a toner agitator assembly and an encoded member
A toner container includes a housing having a toner reservoir. An input gear is positioned on the housing for mating with a corresponding output gear in an image forming device when the toner container is installed in the image forming device. A toner agitator is movably positioned in the reservoir. The toner agitator is operatively connected to the input gear such that rotation of the input gear in a first rotational direction causes movement of the toner agitator for agitating toner in the reservoir. An encoded member is encoded with authentication information of the toner container and is operatively connected to the input gear such that rotation of the input gear in a second rotational direction causes movement of the encoded member for communicating the authentication information of the toner container to a controller of the image forming device when the toner container is installed in the image forming device.
1. A toner container for use in an electrophotographic image forming device, comprising:
a housing having a reservoir for storing toner;
an input gear positioned on the housing for mating with a corresponding output gear in the image forming device when the toner container is installed in the image forming device;
a toner agitator movably positioned in the reservoir, the toner agitator is operatively connected to the input gear such that rotation of the input gear in a first rotational direction causes movement of the toner agitator for agitating toner in the reservoir; and
an encoded member encoded with authentication information of the toner container and operatively connected to the input gear such that rotation of the input gear in a second rotational direction causes movement of the encoded member, at least a portion of the encoded member is exposed on an exterior of the toner container for communicating the authentication information of the toner container to a sensor of the image forming device when the toner container is installed in the image forming device.
2. The toner container of claim 1 , further comprising a one-way clutch positioned to decouple the toner agitator from the input gear when the input gear rotates in the second rotational direction such that the toner agitator does not move with the input gear when the input gear rotates in the second rotational direction.
3. The toner container of claim 1 , wherein the toner agitator includes a shaft rotatably positioned in the reservoir and a plurality of extensions outward from the shaft for agitating toner in the reservoir.
4. The toner container of claim 1 , wherein the toner agitator includes a rotatable auger positioned to move toner to an outlet port on the housing for exiting toner from the toner container.
5. The toner container of claim 1 , wherein the encoded member is rotatably connected to the input gear such that rotation of the input gear in the second rotational direction causes rotation of the encoded member.
6. The toner container of claim 5 , wherein the encoded member is positioned on an axial face of the input gear.
7. The toner container of claim 5 , wherein the encoded member is coaxial with the input gear.
8. The toner container of claim 1 , wherein the encoded member is directly connected to the input gear.
9. The toner container of claim 1 , wherein the encoded member is encoded with authentication information of the toner container by a random distribution of magnetized particles dispersed on the encoded member.
10. The toner container of claim 1 , wherein the portion of the encoded member is exposed on the exterior of the toner container above a rotational axis of the input gear.
11. The toner container of claim 1 , wherein the portion of the encoded member is exposed on the exterior of the toner container through a cutout in the housing of the toner container.
