  • Patent number: 11221582
    Abstract: 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.

  • Patent number: 9367029
    Abstract: A reusable and resettable separator for use with electrophotographic components of an imaging device. The separator is installed with the imaging device and includes a spring-biased lift rail and release linkage and is used to move either a developer unit or a photoconductive drum unit between an operative position where a developer roll and a photoconductive drum form a contact nip and a separated position where the two rolls are separated. The separator is initially set using the lift rail to place two rolls in the separated position with the release linkage engaging the lift rail to hold this position. Opening of an access door engages a one-way release arm actuating the release linkage allowing the lift rail to translate moving the two rolls to the operative position. When reshipment of the imaging device is needed, the separator can manually reset placing the two rolls back in the separated position.

  • Patent number: 9302863
    Abstract: A method for adjusting a pick height of a pick mechanism includes determining a media type for a media stack. When the media type is a first media type, the lift plate is raised to raise the media stack and pick mechanism until a first light blocking region of a flag extending from the pick mechanism blocks an optical path of a sensor indicating that the pick mechanism has reached a first pick height. When the media type is a second media type, the lift plate is raised to raise the media stack and pick mechanism such that the first light blocking region first blocks the optical path, a first light passing region of the flag subsequently unblocks the optical path, and then a second light blocking region of the flag subsequently blocks the optical path indicating that the pick mechanism has reached a second pick height.

  • Patent number: 8474812
    Abstract: A system for manual adjustment of a pick mechanism between multiple positions transverse to a media feed direction associated with different widths of media such that pick forces are substantially balanced about the centerline of a media sheet to be picked. The system includes a shaft for receiving torque, a pick mechanism having a pick arm, and a pick arm adjustment mechanism coupled to the pick mechanism during translating of the pick arm. The pick arm is rotatably and slidably mounted at a first end thereof on the shaft. The pick arm adjustment mechanism comprises a translating member rotatably and slidably mounted on the shaft and coupled to a portion of the first end of the pick arm allowing the pick mechanism to be lifted from a topmost media sheet and allow manual translation of the translating member and pick arm to one of the plurality of predetermined positions.

  • Patent number: 8322709
    Abstract: A method for indexing a lift plate in an image forming device according to one exemplary embodiment includes driving a motor in a first direction to drive a pick mechanism for feeding media from a stack of media sheets on a raisable lift plate such that as media is fed the height of the pick mechanism decreases. When the height of the pick mechanism falls below a predetermined level, the motor is driven a predetermined amount of rotation in a second direction opposite the first direction to raise the lift plate in order to raise the pick mechanism to a desired pick height.

  • Patent number: 8322704
    Abstract: A system that reduces pick skew and improves reliability of a picking mechanism by moving the pick arm to multiple locations across a media feed direction based on media size such that media pick forces are substantially balanced about the centerline of a media sheet to be picked. The system includes a pick arm slidably mounted on a shaft, at least one pick roller mounted to an end of the pick arm for contacting a top sheet of a stack of media sheets and driven to pick media sheets one at a time therefrom, and a pick arm translation mechanism for moving the pick arm along the shaft based on media sheet size of the media stack such that the at least one pick roller remains substantially evenly positioned about a centerline of a media sheet in a media feed direction.

  • Patent number: 8210522
    Abstract: A method for positioning and feeding media into a media feed path according to one embodiment includes moving a first media sheet from the top of a stack of media sheets in a media storage location in a media process direction from an initial pick position into a media feed path leaving a second media sheet at the top of the stack of media sheets. In the media storage location, the second media sheet is moved opposite the media process direction away from an entrance to the media feed path until a leading edge of the second media sheet reaches a known predetermined position in the media storage location. After the leading edge of the second media sheet reaches the known predetermined position, the second media sheet is moved in the media process direction from the stack of media sheets into the media feed path.

  • Patent number: 8210521
    Abstract: A pick mechanism according to one exemplary embodiment includes transmission housing and a drive transmission engageable with a drive shaft for receiving rotational force from the drive shaft. A pick axle has at least one pick wheel mounted thereon and is operatively connected to the drive transmission for rotating the at least one pick wheel. A first stop extends from the transmission housing for limiting the rotation of the pick mechanism about the drive shaft. A method for feeding compressible media according to one embodiment includes rotating a pick mechanism downward about a drive shaft, limiting the downward rotation of the pick mechanism to convert the pick mechanism from a compliant element to a non-compliant element, and feeding a first compressible media from a top surface of a lift plate in a media process direction with the non-compliant pick mechanism.
