Called a Canon copier dealer today. Here's what he said regarding the copying of currency [only after my convincing him I was not inter- ested in a career in funny money]: All Canon color copiers have _always_ marked their output with the serial number of the machine on which they were produced. [I failed to ask about non-color copiers.] He mentioned, specifically, currency, photographs and food stamps as examples of copied items from which the serial number could be recovered by Canon. Canon color laser copiers CL-300 and CL-500, not currently being produced, but still available, do _not_ have the anti-currency device included. They _do_, he said, place the machine serial number in copies made. Canon color laser copiers CL-350 and CL-550 _do_ have the anti- currency device included, which he said is a black box to local repair- men. He continued to say that not only would these models, when given currency to copy, produce only a black rectangle, but also: - store a copy of what one had attempted to copy in memory, and; - lock the machine in such a manner that only someone from the Canon factory "might" be able to render the machine useable. These machines also place the machine serial number in copies it allows to be made, he said. Only on the last item did his answer seem uncertain. His first response was that "the machine would be virtually destroyed." Anyone want to test this for us? He _did_ suggest which Canon copier would do a good job copying currency. I still haven't found the trade mag in which I originally read this...
Since the copiers in question have a digi interface and when connected to Raster Image Processor (RIP) can act (for example) like a postscript printer, one should have to scan in a dollar on a 600 dpi scanner, and print is through the copier as a postscript file. The question is would the black box catch that? It is true about the Anti-Copy device, but I doubt it disables the machine, probally just doesn't copy. These machines are $50,000+ and up in price. /hawk a conscious being, XXCLARK@indst.indstate.edu wrote:
