[QUOTE="davidh, post: 543071, member: 15062"]I don't know how many scanner manufacturers use their own electronics. I kind of suspect that there are standard chipsets used in the printers. Regardless of who makes them, these chips have been mandated by Big Brother to contain certain pattern recognition features that detect when a piece of currency is being scanned, and to alter the scan when detected. These chips aren't in the older scanners which should still be able to scan bills without problems. My 3100 series HP scanner has no problems doing this. Additionally, the newer scanners can probably scan older bills than don't have the current security features. A description of exactly what the security features are that the scanner software looks for is nearly impossible to find. At some time in the past I did read something that I can't find now that described a few of the features. The only thing I remember now dealt with the $20 bills. If you look on the back of the 2004 series bills in the lighter areas you can see scores of tiny 20s printed in yellow. These are arranged in a seemingly random pattern but are actually in a specific pattern that the scanner recognizes. As alluded to in other posts here, some printer and image processing software contains the same recognition features and will not print images of bills Unless laws have been changed I think you can print images of bills if you manage to copy them, if they are enlarged in size by at least 50%, reduced in size by at least 25% or printed in black and white at any size. If you can't scan the bills you want, your only options seem to be to buy an older scanner without the recognition software or photograph the bill and copy it to file.[/QUOTE]
