Zusammenfassung:A paper conditioner (100) to control image dependent curl which uses one or more counterrotating transfer rollers (102, 103) which are initially spaced from their respective back-up rollers (104, 105) in the intercopy gap, and which come together as the lead edge enters the nip area, and separates when the trail edge is about to pass. This permits the rollers to have a less demanding runout tolerance by bringing the rollers together when the sheet is in the nip, and then articulating the rollers apart in the intercopy gap.
