Abstract: A first replaceable unit is provided for use with a second replaceable unit in an electrophotographic image forming device. The first replaceable unit includes a latch movable between a latching position for latching the first replaceable unit to the second replaceable unit and an unlatching position for permitting the first replaceable unit to separate from the second replaceable unit. The latch is positioned to contact a latch catch on the second replaceable unit in order to prevent the first replaceable unit from separating from the second replaceable unit when the first replaceable unit is mated with the second replaceable unit and the latch is in the latching position. The latch includes a cam follower surface for contacting a camming surface on the second replaceable unit during mating of the first replaceable unit with the second replaceable unit to cause the latch to move toward the latching or unlatching position.

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.

Abstract: A toner container includes an encoded member that is encoded with identifying information of the toner container and that is operatively connected to an input gear of the toner container such that rotation of the input gear causes movement of the encoded member for communicating the identifying information to a sensor. A first alignment guide on the first side of the toner container includes a top surface that is unobstructed to contact a sensor housing from below when the toner container is installed in an image forming device. At least a portion of the top surface of the first alignment guide inclines upward and rearward for contacting and lifting the sensor housing upward during insertion of the toner container into the image forming device for aligning the sensor with an exposed portion of the encoded member.

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.

Abstract: A sealing assembly according to one example embodiment includes a housing and an imaging component positioned on the housing. A seal has opposed first and second edges extending along a longitudinal dimension of the seal. A lateral dimension of the seal is perpendicular to the longitudinal dimension and extends in a direction from the first edge to the second edge. The seal is attached to the housing along the first edge and contacts the imaging component along the second edge. Upon attachment to the housing, the seal is elastically deformed from an unassembled state in which the second edge has a first profile that varies in the lateral dimension along the longitudinal dimension to an assembled state in which the second edge is deformed relative to the first profile to a second profile having less variation in the lateral dimension along the longitudinal dimension than the first profile.

Abstract: An electrophotographic image forming device according to one example includes a toner cartridge having a housing that includes a toner reservoir. An electrical connector 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. The electrical connector and the electrical contact of the toner cartridge move upward toward the top of the housing when the electrical connector moves from the retracted position to the operative position. The electrical contact of the toner cartridge is positioned within a pocket of the electrical connector. The pocket includes an opening that faces upward when the electrical connector is in the operative position permitting the corresponding electrical contact in the image forming device to enter the pocket from above.

Abstract: A toner cartridge according to one embodiment includes an outlet port positioned on the front of a housing for exiting toner from the toner cartridge. 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 in a frontward direction of the housing at the rear of the housing. The second engagement surface is positioned proximate the front of the housing below the outlet port. 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 moves in the frontward direction and protrudes from the front of the housing with at least a portion of the front of the second engagement surface unobstructed.

Abstract: A component separator system for use with an electrophotographic image forming device according to one example embodiment includes a first replaceable unit and a second replaceable unit for use in the image forming device. The second replaceable unit is manually separable from the first replaceable unit. The first replaceable unit is mateable with the second replaceable unit in an operative position of the first replaceable unit relative to the second replaceable unit with a first imaging component of the first replaceable unit in operative contact with a second imaging component of the second replaceable unit. Engagement of a first engagement member of the first replaceable unit with a second engagement member of the second replaceable unit retains the first replaceable unit in a storage position relative to the second replaceable unit with the first imaging component spaced away from the second imaging component.
