Abstract

Improving document handling reliability with an auto-make ready feature in which sets containing "difficult" originals are shunted during the first circulation into the document handler output tray, rather than recirculated, while the copies resulting from the first circulation are restacked into the document handler tray, to be used as make-ready originals for the remaining copy sets required. [See Xerox Corporation U.S. 4, 391,504 for background]. This encourages the use of make-readies. By first feeding A-4 size originals into the SADH input of the RDH, one can produce make-ready of A-3 originals, with subsequent blow-back to A-3, copies to also give a throughput advantage.

A current focus in the marketplace is on "intelligent" machines. These are "intelligent" in the way they operate, meaning that they monitor their own performance and adapt to changing conditions. They are also perceived to be intelligent by their operators, due to their ability to understand and satisfy the operators objectives. An implicit requirement in the perception of intelligence is high reliability, which translates to minimizing unscheduled maintenance and machine shut-downs. The concept here is intended to enable a reliability improvement over the way machines are currently built, either through a self- sensing scenario, or through inherently more reliable design, or a feature that the operator would interpret as machine intelligence. As one means of improving document handling reliability, this auto make-ready feature is proposed.

The most challenging aspects of document handling are feeding, restacking and refeeding difficult originals. Difficult originals can include documents of unusually high or low basis weight, poor condition, excessive curl or folds, paste ups and or odd sizes. The intelligent auto make-ready feature will utilize information collected from a number of sources including; customer input basis weight sensors, in-tray document size sensors, stack height, weight or curl sensors and determining whether a particular set of originals contains "difficult" originals. Once this determination has been made the document handler and copy handling module will perform the following sequence:

The originals will initially be fed in the usual way, either through the recirculating document handler RDH input tray or its SADH bypass slot. However, instead...
