ABSTRACT:
A processor for use in processing sheets of photosensitive material has a plurality of processing stations. A plurality of drive rollers define a sheet processing path through the processing stations and are driven to transport a sheet of photosensitive material along that path. The drive rollers at the processing station at the end of the path are driven at a faster rate of rotation than the drive rollers at previous processing stations along the path. The drive rollers of those previous processing stations, however, are mounted to permit said rollers to overrun their driven slower rate of rotation and permit those rollers to rotate at the faster rate of rotation.
