Abstract:
1. A printing system comprising: an inkjet printhead assembly for printing onto print media moved through a print zone, the inkjet printhead assembly comprising a staggered array of stationary overlapping printheads, each printhead being replaceable and shorter than a media width, such that the staggered array collectively spans across the media width; a media path extending through the print zone; a drive roller for moving media along the media path; a vacuum belt assembly positioned downstream only of the inkjet printhead assembly to move the media away from the print zone, the vacuum belt assembly comprising a plurality of individual moving belts and a vacuum chamber for drawing the media onto the plurality of individual moving belts; and, a scanner adjacent the vacuum belt assembly, the scanner being configured for optically capturing printed information from the media for feedback control of the printhead assembly, wherein the printed information is printed by the inkjet printhead assembly, and wherein the information captured by the scanner is used to align printing from each of the printheads with that of overlapping adjacent printheads in the staggered array.
