DUPLEXING PAPER HANDLING SYSTEM

摘要

DUPLEXING PAPER HANDLING SYSTEM An automatic paper handling system capable of loading individual sheets of a stack of paper onto a drum for printing or scanning, escaping a printing or scanning transducer relative to the drum, and stacking the sheet of paper after printing or scanning is additionally provided with duplexing capability to print or scan on the opposite side of a page of paper previously mounted to the drum without the requirement for manual reloading of the page by an operation. During unloading of the page after printing or scanning on a first side thereof a deflector path is interposed in the paper unloading path to cause the trailing edge of the paper during unloading to become the leading edge of the paper for a succeeding loading operation such that the side of the paper previously in contact with the drum will become the side of the paper exposed to the printing or scanning transducer.
