Zusammenfassung:	Methods and apparatus pertaining to scanning or copying documents are provided. Sheet media are individually transported away from an input location. Optical scanning of the sheet media is initiated in accordance with detecting the passage of leading edges of the sheet media. Electronic signals resulting from the scanning are automatically analyzed to detect trailing edges of overlapping sheet media. A user notification is issued if a multiple sheet pick event is detected. A user can resume scanning or copying of a multiple sheet document at the location where the multiple sheet pick occurred.
