Abstract: A system for verifying accuracy of a raster scanned image of a document (20) includes an input tray (30) that holds documents prior to imaging; an input imaging device (40) that captures an image of a document in the input tray; transmitting the captured input tray image to an image processor (100); transporting the document through a document scanner (10); a raster capture device for capturing a raster scanned image of the document with; transmitting the raster scanned image to the image processor; and verifying the accuracy of the raster scanned image by comparing the raster scanned image of the document to the input tray image of the document.

Abstract: A method for preventing damage to a document by a document transport apparatus provides a member for receiving the document as a stack of sheets to be serial fed to a feeding station. At least two spaced-apart microphones are disposed at the feeding station and responsive to audio to produce signals representing audio energy received by each microphone respectively. The energy received from each microphone is compared to determine if it is ambient noise or if it indicates that two attached sheets are being fed or a single sheet is being damaged. The document transport apparatus is shut off to prevent damage to documents when it has been determined that two attached sheets are being fed or that a single sheet is being damaged.

Abstract: A system for capturing an image of a document includes an input tray (30) for holding documents (20); an input imaging device (40) that captures an image of a first document in the input tray; wherein the input tray image of the first document is captured as an area image; transmitting the captured input tray image of the first document to an image processor (100); and transporting the first document to an output tray.

Abstract: A document handling apparatus having a document transport path for moving a document therethrough. A detector proximate the transport detects a multifeed indication in the transport path or a misfeed indication in the transport path. A processing system processes the indications and issues a termination signal if a multifeed or a misfeed, or both, is determined.

Abstract: A method for feeding sheets through a sheet transport path. Ultrasonic energy is directed toward a sheet in the transport path while an audio receiver detects audio data generated by the ultrasonic source and the mechanisms that transport the sheet. The audio data is processed to determine whether a multifeed or a misfeed condition exists in the transport path.
