  • Patent number: 10160232
    Abstract: A media transport system for conveying sheets of media along a process path extending from a media-uptake zone and thereafter through a print zone. The system includes a transport belt for holding the sheets of media generally flat via vacuum for ink jet printing. The media transport system includes a seamed vacuum transport belt, and a platen supporting the belt. The belt comprises a partially-conductive coating having a surface resistivity of from about 101 to about 106 ohms per square on a polymeric substrate. The partially-conductive coating comprises a polyester and a conductive component such as carbon black, and optionally includes a plasticizer and a leveling agent. The polymeric substrate is either a thermoplastic or a thermoset material.
