A document scanner () includes an input tray () for holding documents () and an input image capture device () for capturing images of the documents () in the input tray () prior to transporting the document for imaging; an output tray () for holding documents () after the documents () exit the scanner; an output image capture device () for capturing images of the output tray; an image processor for determining characteristics of the output tray or characteristic of the documents () before imaging and after the documents () exit the scanner; and scanner functions are modified based on the output tray characteristics or the document characteristics.

Verifying accuracy of a scanned document

A system for verifying accuracy of a raster scanned image of a document () includes an input tray () that holds documents prior to imaging; an input imaging device () that captures an image of a document in the input tray; transmitting the captured input tray image to an image processor (); transporting the document through a document scanner (); 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.

System for verifying accuracy of a raster scanned image of a document

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.

Jam sensing at document feeding station

A document scanner () includes an input tray () for holding documents () and an input image capture device () for capturing images of the documents ()in the input tray () prior to transporting the document for imaging; an output tray () for holding documents () after the documents () exit the scanner; an output image capture device () for capturing images of the output tray; an image processor for determining characteristics of the output tray or characteristic of the documents () before imaging and after the documents () exit the scanner; and scanner functions are modified based on the output tray characteristics or the document characteristics.

Method of capturing an image of a document

A system for capturing an image of a document includes an input tray () for holding documents (); an input imaging device () 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 (); and transporting the first document to an output tray.

System for capturing an image of a document

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.

Combined ultrasonic-based multifeed detection system and sound-based damage detection system

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.

Combined ultrasonic-based multifeed detection method and sound-based damage detection method

A document scanner () includes an input tray () for holding documents () prior to imaging; an output tray () for holding documents after the documents exit the scanner; an output image capture device () for capturing images of the output tray; an image processor for determining characteristics of the output tray or characteristic of the documents after the documents exit the scanner; and scanner functions are modified based on the output tray characteristics or the document characteristics.

Method of scanning documents

Document scanner

An apparatus for detection of multiple documents () in a document transport system comprises a transmitter (), located on a first side of a document feed path (), and emits a signal through the document feed path. A reflector (), 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.
