Abstract: Edge hold down (EHD) systems are described herein that enable high print quality to be achieved more consistently, particularly when using substrates that are rigid or include one or more defects. Each EHD system includes a tensioned band for holding down an edge of a substrate as it passes through a printer assembly without impacting the print area. The tensioned band can be affixed between an entry tension assembly and an exit tension assembly disposed downstream of the entry tension assembly in the media feed direction. The tensioned band holds the substrate substantially flat against a transfer belt during printing by applying pressure to the surface of the substrate. The tensioned band generally contacts the surface of the substrate substantially proximate to an outer edge that is parallel to the media feed direction.
