1. A document scanner comprising:
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
wherein document scanner functions are modified based on said output tray characteristics or said document characteristics.
2. A document scanner as in claim 1 comprising an input image capture device for capturing images of documents in the input tray.
3. A document scanner as in claim 1 wherein images of documents are captured as they exit the scanner.
4. A document scanner as in claim 1 wherein images of the documents are captured after they exit the scanner.

8. A document scanner as in claim 7 wherein an operator is alerted if the documents are improperly stacked.
9. A document scanner comprising:
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;
wherein document scanner functions are modified based on said output tray characteristics or said document characteristics: and
wherein the processor determines if the documents are improperly stacked due to output tray side guides or end stop.
10. A document scanner as in claim 1 wherein the processor compares the input condition of the document to the output condition of the document.
