Patent number: 11014384Abstract: 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.Type: GrantFiled: March 29, 2016Date of Patent: May 25, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: Alexander Toia, Kevin Witkoe, Jerrod Houston Tyler, Bruce A Axten

Patent number: 9649862Abstract: A printing system includes a printhead to eject ink onto a print medium in a print zone. A first roller pair is adjacent to the print zone to advance a print medium into the print zone. A second roller pair upstream from the first roller pair, and driven by an independent motor, advances the print medium to the first roller pair in a position control mode. A controller causes the second roller pair to switch from the position control mode to a force control mode when a leading edge of the print medium reaches the first roller pair. The second roller pair applies a substantially constant force to the print medium in the force control mode to push the leading edge of the print medium against the first roller pair while the first roller pair is stationary.Type: GrantFiled: July 23, 2015Date of Patent: May 16, 2017Assignee: Hewlett-Packard Development Company, L.P.Inventors: Luke P. Sosnowski, Pierre J. Kaiser, Alexander Toia, Arthur H. Barnes, Erich Waldherr Hacker

Patent number: 9370944Abstract: A printer system includes a handling system to move print media, a print medium detection sensor to produce a response indicative of an object, and a processor coupled to the handling system and to the print medium detection sensor to perform a two-point calibration of the sensor. The first point of the two-point calibration includes a first response from the sensor, and a second point of the two-point calibration includes a second response from the sensor.Type: GrantFiled: January 31, 2013Date of Patent: June 21, 2016Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Arthur Barnes, Pierre J. Kaiser, Alexander Toia

Patent number: 9302505Abstract: A method for media jam clearing includes detecting a media jam with sensor in the printer, in which the media jam comprises a sheet of media stuck in a media path of the printer. The method further includes monitoring for user action that alters the mechanically alters the state of the printer and detecting a user action that mechanically alters the state of the printer. In response to detection of the user action, the printer automatically attempts to clear the media jam.Type: GrantFiled: September 27, 2012Date of Patent: April 5, 2016Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Alexander Toia, Luke P. Sosnowski, Michael James Rode, Richard Scott Smith
