Abstract
An apparatus () and method () for media hold down transport air flow in an image production device is disclosed. The apparatus can include a media transport belt () configured to transport media sheets () in a process direction (). The media transport belt can include a plurality of belt apertures () arranged along a cross-process direction (), where the cross-process direction is perpendicular to the process direction. The plurality of belt apertures can be configured to conduct air to secure the media sheets on the media transport belt. The apparatus can include a vacuum plenum assembly (). The vacuum plenum assembly can include a plurality of plenum apertures () arranged along the cross-process direction. The plurality of plenum apertures can be configured to conduct air through at least some of the plurality of belt apertures. The plurality of plenum apertures can include at least a first plenum aperture () of a first width () in the cross-process direction and at least a second plenum aperture () of a second width () in the cross-process direction, where the first width can be different from the second width. The apparatus can include a media transport shift assembly () configured to shift a relative position between the media transport belt and the vacuum plenum assembly in the cross-process direction to align at least some of the plurality of belt apertures with at least some of the plurality of plenum apertures.
