  • Controlling drive settings in a press
    Patent number: 8844784
    Abstract: In one embodiment, a method for controlling drive settings in a press for printing on a web of media. A drive is provided to receive the web from an upstream location and to transport the received web downstream of the drive at a controllable speed. The speed of the drive is sampled plural times while operating the drive in a tension control mode that varies the speed to maintain a desired tension in the web adjacent the drive. An optimal speed of the drive is calculated from the sampled speeds. The drive is operated in a constant velocity mode at the optimal speed during printing.

  • Counteracting expansion effects of moisture on media within fluid-ejection device
    Patent number: 8696082
    Abstract: Expansion effects of moisture on media resulting from ejection of fluid by the fluid-ejection device onto the media within a print zone in accordance with a portion of a print job are inferred. In response to inferring the expansion effects of moisture on the media, an action is performed to counteract the expansion effects of moisture on the media.
