  • Publication number: 20210255580
    Abstract: 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.

  • Publication number: 20210063955
    Abstract: An assembly for an electrophotographic image forming device includes a housing and a rotatable component. A bushing has an opening defined by an inner circumferential surface of the bushing. A shaft of the rotatable component is received in the opening such that the inner circumferential surface rotatably supports the shaft. A first mating feature is positioned on an outer surface of the bushing that is opposite the inner circumferential surface of the bushing. The first mating feature is positioned between an inner axial end of the bushing and an outer axial end of the bushing relative to a rotational axis of the rotatable component. The first mating feature of the bushing is in contact with a second mating feature on the housing. Contact between the first and second mating features defines an axial position of the bushing relative to the housing along the rotational axis of the rotatable component.

  • Publication number: 20210026291
    Abstract: 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.

  • Publication number: 20210018864
    Abstract: An assembly for use in an electrophotographic image forming device includes a housing having a reservoir for holding toner. The housing includes a wall having an inner surface forming a boundary of the reservoir and an outer surface opposite the inner surface. A toner agitator is positioned in the reservoir and has a rotatable shaft. The shaft includes an end portion that passes through an opening in the wall. A gear is mounted on the end portion of the shaft outside of the reservoir and is rotatably coupled to the shaft. An annular seal encircles and is in contact with an outer circumferential surface of the shaft. The annular seal is positioned between an inner axial face of the gear and the outer surface of the wall. The inner axial face of the gear contacts the annular seal and presses the annular seal against the outer surface of the wall.

    Abstract: Techniques for implementing robust quantum logic gates are provided and described. In some aspects, a quantum logic gate between a plurality of cavities comprising a first cavity and a second cavity is implemented by performing a first beam splitter operation between the first cavity and the second cavity using a coupling transmon that is dispersively coupled to both the first cavity and the second cavity, and performing a controlled phase shift operation between the second cavity and an ancilla transmon that is dispersively coupled to the second cavity but not dispersively coupled to the first cavity.
