A toner cartridge according to one example embodiment includes a housing having a reservoir for holding toner. A first latch-receiving shelf is positioned on a first longitudinal end of the housing and a second latch-receiving shelf is positioned on a second longitudinal end of the housing. Contact surfaces on top portions of the first and second latch-receiving shelves are positioned to contact corresponding first and second latches in an image forming device. The contact surface of the first latch-receiving shelf is positioned lower than a first rotational axis of a first drive coupler of the toner cartridge and higher than a second drive coupler of the toner cartridge. The contact surface of the second latch-receiving shelf is positioned lower than at least a portion of a first electrical contact of the toner cartridge and higher than at least a portion of a second electrical contact of the toner cartridge.

Toner cartridge having positioning features

A toner cartridge according to one example embodiment includes a housing having a reservoir for holding toner. A first electrical contact and a second electrical contact are positioned on a first longitudinal end of the housing. The first electrical contact is electrically connected to processing circuitry positioned on the housing. The second electrical contact is electrically connected to an imaging component positioned on the housing. The first electrical contact is positioned higher than the second electrical contact. A first drive coupler and a second drive coupler are positioned on a second longitudinal end of the housing. The first electrical contact and the second electrical contact are positioned higher than a first rotational axis of the first drive coupler. The first electrical contact is positioned higher than a second rotational axis of the second drive coupler and the second electrical contact is positioned lower than the second rotational axis.

Toner cartridge electrical contacts

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.

Sealing assembly for an electrophotographic image forming device

A toner cartridge includes a photoconductive drum and a boss that protrudes outward from a first longitudinal end of the toner cartridge at a rotational axis of the photoconductive drum. An outermost axial segment of the boss along the rotational axis includes a partial cylinder having a cross-sectional shape of a circular segment. An outer circumferential surface of the partial cylinder is convex to a bottom of the toner cartridge and forms a bottom contact surface of the boss that is unobstructed to contact and sit in a corresponding V-block in an image forming device when the toner cartridge is installed in the image forming device. The outermost axial segment of the boss includes clearance above a topmost portion of the partial cylinder and within the radius of the outer circumferential surface of the partial cylinder permitting the clearance to accommodate one or more features in the image forming device.

Toner cartridge having a positioning boss

Toner cartridge

A system for an electrophotographic image forming device includes a basket having a first side, a second side and a plurality of positioning slots extending between the first side and the second side, each positioning slot is configured to receive a corresponding toner cartridge. Each positioning slot includes a first latch at the first side of the basket and a second latch at the second side of the basket. Each of the first and second latches is independently pivotable between a latched position for applying a hold-down force on a respective end portion of a corresponding toner cartridge positioned in a corresponding positioning slot of the plurality of positioning slots to rigidly hold the corresponding toner cartridge against datums of the basket and an unlatched position to release the corresponding toner cartridge permitting removal of the corresponding toner cartridge from the basket.

Latching assembly for securing toner cartridges in an image forming device

A system for an electrophotographic image forming device includes a basket insertable into and extendable out of the image forming device. The basket includes a plurality of positioning slots each configured to receive a corresponding toner cartridge of a plurality of toner cartridges. The basket includes a cartridge latching assembly configured to apply a hold-down force on each toner cartridge to rigidly hold each toner cartridge against corresponding datums of the basket. A basket latching assembly in the image forming device is configured to apply a hold-down force on the basket when the basket is inserted into the image forming device to rigidly hold the basket against corresponding datums of the image forming device for positioning the plurality of toner cartridges in respective operational positions within the image forming device with only the cartridge latching assembly of the basket directly applying hold-down forces on the plurality of toner cartridges.
