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.

A printer as a medium processing apparatus includes a transport path through which a paper being transported passes, a recording head that records on the paper on the transport path, and a platen that forms at least a portion of the transport path as a path forming member with which the paper comes into contact, in which a surface resistance value of the path forming member changes according to an applied voltage of the medium.

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.

A sheet feeder, which is incorporated in an image forming apparatus, includes an attraction body disposed facing a bundle of sheets, a charger to charge the attraction body to electrostatically attract an uppermost sheet of the bundle of sheets to the attraction body, a liquid supplier to supply a liquid to dissolve discharge products to the attraction body, and a liquid remover to remove the liquid from the attraction body. Further, a method of removing discharge products includes counting the number of sheets fed from a sheet container, determining that the number of sheets reaches a predetermined threshold value, confirming that a current time falls within a predetermined period of time or receiving a turn off signal to turn off a power supply, removing the discharge products from a surface of an attraction body, and resetting the number of sheets or further turning off the power supply.

A flexible and continuous substrates-conveying sheet has a plurality of to be processed substrates disposed on or in it. A nondestructive transferring unit includes a plurality of first transferring rolls and a plurality of second transferring rolls. The first transferring rolls make contact with a first surface of the substrates-conveying sheet where that surface can have electrostatically-induced charge formed thereon. Each of the first transferring rolls includes a first central portion charged with a positive electric charge and a first outer portion surrounding the first central portion. The second transferring rolls make contact with the first surface of the substrates-conveying sheet. The second transferring rolls are disposed alternately with the first transferring rolls. Each of the second transferring rolls includes a second central portion charged with a negative electric charge and a second outer portion surrounding the second central portion.

The medium supporting device comprises an electrostatic chucking mat generating an electrostatic chucking force by being energized, and a support for supporting the electrostatic chucking mat movably in a first direction. The support is removably connected to a cutting plotter. The cutting plotter includes a medium feeding mechanism for moving a medium reciprocally in the first direction. The electrostatic chucking mat is moved by the medium feeding mechanism while the medium is chucked.
