Abstract

A copy sheet registration arrangement is arranged for a copier/finisher system. Sheets which are transported to a compiler station for the finisher are subject to two-step registration positioning. In the first step, the sheets are shifted from a centerline of the paper path leaving the copier to a parallel centerline of the paper path to the compiler station. In so shifting, they are course registered on an edge parallel to the centerlines, the edge being the top edge of each sheet as viewed when reading. In this manner, the registration is equally effective regardless of the various sizes copy sheets may take. A second top edge registration which is more accurate and a side edge registration occur.
