  • Patent number: 9933727
    Abstract: A toner container includes a housing having a reservoir for holding toner. An inlet port is formed on the housing and in fluid communication with the reservoir for receiving toner. A first shutter member and a second shutter member is positioned about the inlet port and are each pivotable between a closed position and an open position. When the first and second shutter members are in the closed positions, respective free ends thereof seal against each other and respective first face portions of the first and second shutter members seal against a perimeter of the inlet port such that the first and second shutter members block the inlet port. When the first and second shutter members are in the open positions, the first and second shutter members are pivoted away from the inlet port unblocking the inlet port. The first and second shutter members are biased toward the closed positions.

  • Patent number: 9720350
    Abstract: An auger assembly according to one example embodiment includes an auger having a helical flight extending along a longitudinal axis. The auger has a central opening running along the longitudinal axis. The auger has an end that includes at least a portion of a turn having substantially zero pitch. A retaining member has a body including a groove on an outer surface of the body. The groove has a shape complementary to the helical flight at the end of the auger. At least a portion of the end of the auger is retained within the groove. A rotatable coupling member extends along the longitudinal axis. At least a portion of the rotatable coupling member is positioned within the central opening of the auger and presses the outer surface of the retaining member against an inner diameter of the end of the auger.

  • Patent number: 8807564
    Abstract: A media actuated, media diverter mounted on a media guide positioned between the output of a simplex path and the entrance of a duplex path in an imaging device. The media diverter comprises a plate having a media guiding surface and a media contact surface along portions of the edge of the plate. The plate is received within a slot through the guide member such that in a first position the media contact surface extends into the duplex path and when in a second position the media guiding surface extends into the simplex path. The plate's center of gravity moves the contact surface of the plate into the first position. A media sheet fed into the duplex path strikes the media contact surface moving the plate to the second position where the media guiding surface directs a following sheet in the simplex path to an exit of the imaging device.

  • Patent number: 8316733
    Abstract: In an image printing device, such as a laser printer or ink jet printer, a coupling device for creating a coupling between a rotatable shaft and an interface component, such as a gear. The coupling device is an elongated modified c-shaped body having a portion for receiving the rotatable shaft, and includes integrated hinges that facilitate the coupling device to be spread apart and to receive and interface with the rotatable shaft. The integrated hinges function to compress between the rotatable shaft and interface component substantially inhibiting relative longitudinal movement and wherein a flat on the exterior of the rotatable shaft engages with a flat on the interior the interface component, to additionally inhibit relative rotational movement between the interface component and the shaft. The shaft further includes a plurality of ribs that extend from the rotatable shaft into the coupling device providing additional reduction in rotational movement between the shaft and the interface component.
