Combined Ultrasonic-Based Multifeed Detection System And Sound-Based Damage Detection System

摘要

A document handling apparatus having a document transport path for moving a document therethrough. A detector proximate the transport detects a multifeed indication in the transport path or a misfeed indication in the transport path. A processing system processes the indications and issues a termination signal if a multifeed or a misfeed, or both, is determined.
