CONCURRENTLY REMOVING SHEET CHARGE AND CURL

摘要

Decurling a charged sheet and removing charge from the charged sheet prior to stacking, includes forming a nip between a roller and a compliant surface and applying pressure between the roller and compliant surface so that the nip has a decurling shape and when the nip engages the sheet it will perform a decurling function; and moving the charged sheet through the nip while the compliant surface has an AC voltage applied thereto so that a first side of the charged sheet is in contact with the compliant surface and has its charge substantially dissipated, whereby charge substantially remains on a second side of the charged sheet in contact with the roller and curling of the charged sheet is reduced. 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.
