Abstract:
1. A substrate handling system, comprising: a sheet transport section that transports a sheet of image receiving media along a path from a sheet supply, the sheet transport section including a hold section that holds the sheet of image receiving media at a position in the sheet transport section after the sheet supply; a sensor that senses the presence of the sheet of image receiving media at the hold section; a control unit that (1) causes the sheet transport section to perform an initial feed cycle to transport the sheet of image receiving media from the sheet supply to the hold section, (2) receives an input from the sensor regarding whether the sheet of image receiving media is present at the hold section at the completion of the initial feed cycle, and (3) causes the sheet transport section to perform at least one re-feed cycle when the input indicates that the sheet of image receiving media is not present at the hold section at the completion of the initial feed cycle; and a marker unit that deposits an image forming material on the sheet of image receiving media, wherein the control unit calculates a maximum number of possible re-feed cycles based on at least one operating parameter of the marker unit, and the marker unit deposits a plurality of image forming materials separately on the sheet of image receiving media, each of the plurality of image forming materials being deposited individually as an individual sub-operation performed by the marker unit, and the calculated maximum number of possible re-feed cycles corresponds to the number of individual sub-operations performed by the marker unit.
