Abstract
A method of removing charge from a charged sheet prior to stacking the charged sheet is disclosed. The method includes moving the charged sheet through a set of nipped rollers while a first roller has an AC voltage applied thereto so that a first side of the charged sheet is in contact with the first roller and has its charge substantially dissipated, whereby charge substantially remains on a second side of the charged sheet in contact with a second roller. The method further includes using at least one non-contact charge removal device to remove charge from the second side of the charged sheet, and stacking the discharged sheet.
