Abstract
An apparatus for detection of multiple documents (10) in a document transport system comprises a transmitter (15), located on a first side of a document feed path (40), and emits a signal through the document feed path. A reflector (52), located on a second side of said document feed path, reflects the signal through the document feed path. A first sensor detects the signal from the transmitter. A second sensor detects the signal from the transmitter.
