US 6,608,989 B2 · Media position retaining device

Abstract

A device and method for retaining media in a predetermined position for imaging. A platen for a flatbed imaging device includes an electrostatic charge that is imparted to the platen either passively or actively. The electrostatic charge is imparted by a movement of a charged object relative to the platen. In one embodiment of the invention, the electrostatic charge is imparted to the platen passively in the sense that the electrostatic charge is imparted by the placement of a platen cover having one triboelectric value in proximity to a platen having another triboelectric value. In an active embodiment of the invention, the electrostatic charge is imparted to the platen actively in the sense that the requisite electrostatic charge is imparted by movement of a charge emitting device, such as a corona wire, in close proximity to the platen.
