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).
Claims23
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 image to the defined set of counterfeit signatures;
- and
- ceasing printer operation if the scanned image includes at least one restricted.
The method of claim 5, further comprising maintaining the printer in a locked state until unlocked by a supplier or manufacturer.

A method of deterring counterfeit reproduction of documents, comprising:
- scanning, with a scanner, a full page image on an imaging member;
- capturing a scanned full page image corresponding to the full page image on the imaging member, wherein the full page image comprises a complete, transferable image as to be output by a printer to a print medium prior to transfer of the complete, transferable image to the print medium;
- comparing the captured full page image to at least one stored criteria from an associated memory resulting in at least one corresponding criteria comparison;
- weighing the at least one criteria comparison resulting in at least one corresponding weighted criteria comparison;
- determining a level of similarity between the captured full page image and at least one restricted image stored in the associated memory using the at least one weighted criteria comparison;
- determining whether the captured full page image includes a restricted image based at least in part on a determined level of similarity relative to a predetermined threshold stored in the associated memory;
- and
- selectively controlling printer processes upon a determination that the captured full page image includes a restricted image.
A method of deterring counterfeit reproduction of documents, comprising:
- scanning a complete, transferable image on an imaging member to be output by a printer to a print medium so as to scan the complete, transferable image;
- capturing a scanned image corresponding to the complete, transferable image;
- comparing the scanned image to at least one stored criteria comparison;
- weighing the at least one criteria comparison resulting in at least one corresponding weighted criteria comparison;
- determining a level of similarity between the scanned image and at least one restricted image stored in the associated memory using the at least one weighted criteria comparison;
- determining whether the scanned image includes a restricted image based at least in part on a determined level of similarity relative to a predetermined threshold stored in the associated;
- and
- ceasing printer operation upon a determination that the scanned image includes at least one restricted image.
