Abstract: 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.

Abstract: A scanner comprises a first gear assembly on a frame, a stationary scan surface having a first width, and a scan module having a length substantially less than the first width. The scan module includes a second gear assembly configured to move the scan module, in a first orientation generally perpendicular to the first width, in a first scanning path relative to a first width portion of the scan surface and in a second, non-duplicative scanning path relative to a second width portion of the scan surface. The second gear assembly is releasably engageable to the first gear assembly to selectively shift the scan module, in a second orientation generally perpendicular to the first orientation, between the respective first and second scanning paths.
