  • Publication number: 20200218175
    Abstract: A replaceable unit is removably installable in an image forming device. The replaceable unit includes a rotatable input gear that is positioned to mate with an output gear of the image forming device. The replaceable unit includes an encoded member that is encoded with identifying information of the replaceable unit and that is operatively connected to the input gear such that rotation of the input gear causes movement of the encoded member. The replaceable unit includes an alignment guide on the exterior of the replaceable unit. The image forming device includes a sensor supported by a sensor housing. The alignment guide is positioned to contact and move the sensor housing during insertion of the replaceable unit into the image forming device to align the sensor with an exposed portion of the encoded member for reading the identifying information from the encoded member by the sensor.

  • Patent number: 10649399
    Abstract: A replaceable unit for an electrophotographic image forming device includes a housing having a reservoir for holding toner. An electrical connector is positioned on a first side of the housing. The electrical connector includes an electrical contact for contacting a corresponding electrical contact in the image forming device and a magnetic sensor electrically connected to the electrical contact. The electrical connector is movable between a first position and a second position. When the electrical connector moves from the first position to the second position, the electrical contact of the replaceable unit moves from a retracted position to an operative position. When the electrical connector moves from the first position to the second position, the magnetic sensor moves from a misaligned position to an aligned position with a point in a path of movement of a magnet for sensing a magnetic field of the magnet.

  • Publication number: 20200117120
    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.

  • 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.

  • 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.
