Abstract

Servo driven restacking of documents in an recirculating document handler, with a small D.C. servo or stepper motor replacing an AC drive motor for the frictional sheet feed drive rollers returning the document from the platen to the restack tray. This permits rapid acceleration of the document to, e.g., 100 ips, once the document trail edge is detected as having left the platen, then controlled deceleration to, e.g., 40 ips, as the document enters the restack tray (before it is released to restack). This is a way of speeding up the document, then slowing it down for low sheet energy stacking and reduced front stack stop impact.
