Abstract
Apparatus for detecting a dimension of a generally rectangular document in a system where the document is carried over a track to a station where the document is scanned by a sensor to create a digital image thereof. Pixel vales along a scan line which includes a portion of the track as well as the document are analyzed and provide an indication of the size of the document.
