Abstract
A media sheet drive has a continuous belt of a dielectric material for transporting sheet media supported on the belt in a transport direction. A launch mechanism is used to launch a sheet medium onto a top surface of the belt. A charging circuit including a charging roller is used to charge a top surface of the sheet medium and the belt as the sheet medium is launched. Charging acts to generate an electrostatic tacking force to tack the sheet medium to the belt. The charging roller has a second function to smooth out curled edges of paper as it is acted on by the charging circuit so that the full extent of a launched sheet medium may be subject to the electrostatic tacking force.
