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 head 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. To prevent high electric field near the belt top surface which might otherwise affect the printing process, a neutralizing circuit is positioned downstream of the charging circuit to reduce electric field near the top of the belt by balancing charge at the top and bottom of the belt while keeping the sheet medium tacked to the belt.
