ABSTRACT:
Signature printing with an automatic duplexing copier by simultaneously presenting plural document sheets to the imaging station of the copier in a predetermined nonserial page order for producing a set of signature copy sheets suitable for subsequent center-folding into signature sets, by loading a normal serial set of document sheets into an automatic document reordering and presenting system (associated with the copier) which automatically reorders that set of document sheets into a predetermined nonserial reordered page order for signature pair page order "two-up" copying, and automatically presenting the pairs of automatically reordered document sheets to the imaging station of the copier to be copied in the reordered page order to provide collated page order signature sets automatically with the copier for on-line center-folding and finishing without requiring any manual reordering of either the document sheets or the signature copy sheets. The automatic reordering includes automatic 180.degree. rotation of alternate pairs of simplex document sheets to provide proper orientation of the document pages for the automatic duplex copier. The document sheets are either automatically separated into two stacks for two document sheets to be presented simultaneously lengthwise (short-edge-first) in parallel to one side of the imaging station, or reordered into one stack for sideways (long-edge-first) presentation from an orthogonal direction.
