Abstract
A multiple feed document detection system for use with a document transport for detecting the presence of multiple documents utilizes multiple doubles detection devices wherein each device detects the presence of doubles. The output signals of each device are applied to a comparator which compares the signals obtained from each device. If each device indicates the presence of doubles, then the comparator provides an output that multiple sheets are present. The system thereby eliminates the reading of false doubles by the comparison of the output signals from two or more doubles detection devices.
