  • Patent number: 11091335
    Abstract: An example bridge module includes a media transport roller to move in a translational direction, a rotatable guide proximate to the media transport roller, a handle coupled to the rotatable guide to cause the rotatable guide to articulate into an open configuration and away from the media transport roller, and an elongated member operatively connected to the rotatable guide, the elongated member to articulate into the open configuration creating an unobstructed pathway to the media transport roller.
    Type: Grant

  • Patent number: 11014384
    Abstract: A pick attempt of a media sheet from a media tray is initiated by rotating a pick roller a number of rotations that is set to greater than one in response to the sheet having been designated as a special media sheet type and that is set to one in response to the sheet not having been so designated. In response to a pick sensor detecting the sheet after the pick attempt has been attempted, a turn roller is rotated to advance the sheet to a print engine, and while the turn roller is rotating, the pick roller is rotated to assist advancement of the media sheet. A controller manages per-sheet and per-tray pick attempt counters while the sheet is individually attempted to be picked and advanced, using the counters to determine whether to initiate another pick attempt of the sheet when a current pick attempt has failed.

  • Publication number: 20200385223
    Abstract: An example apparatus includes a lift plate of a tray to hold a print medium. A support member is operatively connected to the lift plate. A sensor is attached to the support member to measure a distance of the lift plate from the sensor. A processor may receive a measurement of the distance of the lift plate from the sensor, and output an indicator describing an amount of print media in the tray based on the measurement of the distance of the lift plate from the sensor.

  • Patent number: 10571847
    Abstract: In an example implementation, a stackable component assembly includes a first stackable component with a bottom recess in its bottom surface, and a second stackable component with a top recess in its top surface. A first alignment element is installed in the bottom recess and a second alignment element is installed in the top recess. The second alignment element is nestable within the first alignment element to align the first and second stackable components upon stacking the first stackable component onto the second stackable component.

  • Patent number: 10562322
    Abstract: An example assembly includes a first guide positioned in a pre-print zone area of an imaging device. A second guide rotatably is connected to the imaging device and spaced apart from the first guide to permit a print medium to traverse between the first guide and the second guide. A bearing mechanism connects the second guide to the imaging device in the pre-print zone area. An interface mechanism is operatively connected to the second guide. A bias element is positioned between the interface mechanism and the second guide to release energy upon exposing the interface mechanism to the pre-print zone area allowing rotation of the second guide away from the first guide.
