  • Patent number: 6133936
    Abstract: A system for holding recording media onto a media support surface, comprises, a media support element including a media support surface and a second side, substantially opposing the media support surface. A plurality of vacuum ports pass from the media support surface to the second side and communicate with a device for drawing air through each of the plurality of vacuum ports to hold the recording media against said media support surface. A sequencing manifold connected between the device for drawing air and the plurality of vacuum ports selectively draws air through a portion of the plurality of vacuum ports over a region substantially matching the size of the recording media.
