A paper conditioner to control image dependent curl which uses one or more counter-rotating transfer rollers which are initially spaced from their respective back-up rollers 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.

A method of purging copy sheets after a machine malfunction from a copy sheet path having a plurality of zones including the steps of determining the existence of copy sheets in process in any of the copy sheet path zones, selectively activating a plurality of independent copy sheet drives to maintain a predetermined interdocument space between any copy sheets in process and systematically purging the copy sheets from the zones of the paper path in a predetermined order based upon the particular disposition of the copy sheets in the sheet path zones.
