Abstract
Accurate advance of a media sheet is achieved by carrying the media sheet on a belt loop support. An upstream pinch roller holds the media sheet to the belt upstream of the print zone. A downstream pinch roller holds the media sheet to the belt downstream of the print zone. A guide shim extends along the media path from a position upstream of the upstream pinch roller, passed the upstream pinch roller under a printhead adjacent to the print zone. The location of a lead edge of the guide shim relative to the print zone determines the minimum bottom margin for the inkjet printing device. The guide shim presses the media sheet to the belt support and keeps the media sheet flat under the inkjet printhead as the printhead moves over the media sheet.
