Abstract
Accurate advance of a media sheet is achieved by carrying the media sheet on a belt loop. 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 toward the print zone. The guide shim advances with the bottom edge of the media sheet into the print zone to stabilize the trailing edge so as to allow for a smaller minimum bottom margin.
