  • Media detectors
    Patent number: 11214082
    Abstract: A printing apparatus determines a change in torque of a motor that moves a pick arm for translating print media, determines based on the change in torque whether a media in present adjacent to the pick arm.
    Type: Grant
    Filed: July 31, 2017
    Date of Patent: January 4, 2022
    Assignee: Hewlett-Packard Development Company, L.P.

  • Print media amount determination
    Patent number: 10994560
    Abstract: The present subject matter describes determination of amount of print media present in an input tray of a printing system. In an example implementation of the present subject matter, a current operating torque of a motor that moves a pick arm for drawing print media from the input tray is monitored. The current operating torque is monitored while the pick arm is moved between a rest position and a pick-ready position. Based on the monitored operating torque, it is determined whether amount of print media present in the input tray is one of below and above a predefined amount of print media.
