ABSTRACT:
A loop is formed between upstream and downstream pairs of rollers by driving the downstream pair slower than the upstream pair and/or by a direction changing guide. The downstream pair of rollers is axially movable to bring an in-track edge of a sheet to a predetermined sensed position to cross-track register the sheet. The loop permits cross-track movement of the sheet despite engagement of the sheet with the upstream pair of rollers.
