In order to minimize the time required to copy a stack of original documents (throughput), copiers usually run in an overlap mode. That is, original documents which have been copied are exited from the document glass before the final copies have exited from the copier paper path. Subsequent original documents are entered onto the document glass, copied, and exited all while copics of the previous originals may still be in the copier paper path. If a copy jam should occur while the copier is in such an overlap mode, copies from several exited original documents might be involved and be discarded by an operator while clearing the jam. The original documents which had copies lost must somehow be fed back onto the document glass so that their last copies can be remade.
