A system for registering the lead edge of documents being copied on a copier platen to a desired registration position over a downstream edge area on the platen in the direction of document movement. Trail edge document sensing is not desir-able, particularly for an undersized document, where the desired registration edge is at the downstream side of the platen. With the disclosed system there are no registration gates or other document sheet stop mechanisms or sensors over or directly adjacent the platen. Thus, there are no shadows or losses of image area at either edge of the document copy.
