  • Patent number: 10527969
    Abstract: A method of operating an electrophotographic image forming device according to one example embodiment includes, by rotating a motor in a first rotational direction of the motor, rotating an input gear of a toner container in a first rotational direction of the input gear causing a toner agitator in a toner reservoir of the toner container to move for agitating toner in the toner reservoir. By rotating the motor in a second rotational direction of the motor, the input gear of the toner container rotates in a second rotational direction of the input gear causing an encoded member on the toner container to move. A sensor in the electrophotographic image forming device senses identifying information of the toner container encoded on the encoded member during movement of the encoded member and rotation of the input gear of the toner container in the second rotational direction of the input gear.

  • Patent number: 10527967
    Abstract: 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.

  • Publication number: 20190377298
    Abstract: A replaceable unit for an electrophotographic image forming device according to one example includes a housing having a toner reservoir. An electrical connector mounted on the housing is movable between a retracted position and an operative position. The electrical connector includes an electrical contact for contacting a corresponding electrical contact in the image forming device. The electrical contact is electrically connected to processing circuitry on the housing. In the retracted position, the electrical connector is tucked into a portion of the housing. In the operative position, the electrical connector is exposed to permit the electrical contact to contact the corresponding electrical contact in the image forming device. A linkage is operatively connected to the electrical connector and includes an engagement surface accessible on an exterior of the housing to receive an actuation force. Movement of the linkage moves the electrical connector between the retracted position and the operative position.

  • Publication number: 20190369174
    Abstract: A system for use in authentication processes is described comprising a physical unclonable function (“PUF”), a substrate, a plurality of magnetized particles randomly dispersed in the substrate, a PUF reader constructed using multiple discrete magnetometer chips that have magnetic field sensors, placed on a circuit card in an array with a sufficient center to center spacing between sensing elements of adjacent magnetometer chips, wherein the PUF reader measures the magnetic field data at multiple locations in close proximity to the magnetized particles. The measured magnetic field data may be compared to previously enrolled data to assess authenticity.

  • Patent number: 9983508
    Abstract: An image forming device includes a toner cartridge having an outlet port positioned on the front of a housing for transferring toner from a reservoir to a developer unit. The toner cartridge includes an engagement member having a first engagement surface and a second engagement surface. The first engagement surface is positioned proximate the rear of the housing to receive an actuation force from an actuation feature of an image forming device. The second engagement surface is positioned proximate the front of the housing below the outlet port to engage a shutter on an inlet port of the developer unit. The engagement member is movable from a first position to a second position upon receiving the actuation force. As the engagement member moves from the first position to the second position, the second engagement surface protrudes from the front of the housing to engage the shutter of the developer unit.
