Abstract

Systems and methods are described that facilitate counterfeit deterrence in a printer or the like. A final image is scanned from a photoreceptor belt before or after transfer of the image to a print medium or from the print medium itself prior to output, and the scanned image data is assessed using a set of stored criteria to detect counterfeit signatures in the scanned image. Upon a determination that the scanned image includes a restricted image, and therefore contains one or more counterfeit image, the printer is shut down, electronically locked until serviced, and/or caused to damage or mark the printed counterfeit image(s).

First claim

The invention claimed is:

1. A method of deterring counterfeit reproduction of documents, comprising:
scanning a complete, transferable image on an imaging member to be output from a printer to a print medium;
capturing a scanned image corresponding to the complete, transferable image;
comparing the scanned image to a defined set of counterfeit signatures;
determining whether the scanned image includes a restricted image based upon a result of the comparison of the scanned i…
