  • Density modulated auto-duplexing
    Patent number: 10647131
    Abstract: A method for fluid-density modulated auto-duplexing is disclosed. This method determines when a final swath of a printing operation on a surface of a media occurs within a predefined distal end portion of the media. An estimated media dry time after the final swath in the predefined distal end portion is determined to be greater than a predetermined time. The estimated dry time is capped to a predetermined minimum media dry time and a course of action for a feed mechanism is selected to reduce curling and cockling of the media. Furthermore, a non-transitory computer readable medium and a printer having fluid-density modulated auto-duplexing are also disclosed.
