Abstract
A media transport system includes a drum with a plurality of rows of holes, a vacuum plenum, and a shutter. The vacuum plenum is positioned within the drum at a position opposite a printhead and the shutter is configured for movement in a cross-process direction. Each row of holes in the drum includes at least one inter-copy gap. The shutter includes a solid member having at least one aperture in it. The shutter is moved to a position so the aperture is aligned with a row of holes and the solid portion of the shutter prevents a flow of air through the vacuum plenum from the holes in other rows of holes not aligned with the aperture in the shutter and the inter-copy gaps in the row of holes aligned with the aperture selectively prevents air flow to the vacuum plenum.
