  • Patent number: 10668749
    Abstract: In one example, a system for a inline duplexer media path includes a first print media pathway extending from an input roller to an output roller, wherein the first print media pathway provides the print media through a print zone, and a second print media pathway extending from the output roller to the input roller, wherein the second print media pathway is substantially parallel and separate from the first print media pathway.

  • 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.

  • Patent number: 10647132
    Abstract: In one example, a device for partially dried inkjet media output management includes a starwheel positioned on a first side between a number of rollers positioned on a second side to corrugate partially dried inkjet media between the starwheel and the number of rollers.

  • Publication number: 20200130384
    Abstract: An apparatus (102) with moveable platen ribs (110,112), is described. The apparatus comprises a platen (108) for supporting print media (106). The platen extends in a plane in which the print media is conveyed to be printed. The apparatus further includes a first set of platen ribs (110) and a second set of platen ribs (112) each mounted on the platen. The second set of platen ribs are moveable approximately perpendicular to the plane.

  • Publication number: 20200009887
    Abstract: The present subject matter discloses detection of positions of print medium for driving the print medium for printing in a printing system, in an example implementation, a motor is operated for driving the print medium, at a first specific speed, along a media-path in the printing system. After a first specific number of rotations of the motor, it is detected, based on identification of a torque change event, that the print medium at a de-skew position in the media-path. At the de-skew position a leading edge of the print medium is at a de-skew unit of the printing system and the torque change event is indicative of a deviation in a current operating torque of the motor from a standard operating torque of the motor.
