No you don't understand photocopiers will literally brick themselves (only certain models that are a "threat") and if any official tech ever sees the error code (the machine locks out as well and requires service to be unlocked) the legal hammer would come shortly. (Counterfeiting is illegal, no contract is required)
In the unlikely event that any of that is true, please name the manufacturers and jurisdictions in question, so that I may avoid them.
The fact that a copier thinks it has seen a Eurion constellation is nowhere near grounds to brick itself, let alone prosecute anybody.
Adobe (photoshop, ...) have it, Xerox, HP, Brother, Canon, Dell, Epson, IBM, Konica Minolta, ... only certain software/hardware have the anti-counterfeiting systems with high end color ones being very likely to have it. Production level ultra-high end gear is very likely to have lockouts as with the right stock you could probably print money that looks very real. Printer stenography is pretty standard and I use it to verify documents regularly as well. (its funny when you see people not setting the clock correctly, you can trace it right down to the printer that printed it)
Or as wikipedia says "In the late twentieth century advances in computer and photocopy technology made it possible for people without sophisticated training to copy currency easily. In response, national engraving bureaus began to include new more sophisticated anti-counterfeiting systems such as holograms, multi-colored bills, embedded devices such as strips, microprinting, watermarks and inks whose colors changed depending on the angle of the light, and the use of design features such as the "EURion constellation" which disables modern photocopiers. Software programs such as Adobe Photoshop have been modified by their manufacturers to obstruct manipulation of scanned images of banknotes.[18] There also exist patches to counteract these measures."
The dot stenography coding is also an additional "feature" on many color printers, some brands are inconsistent while others have it on every color printer. A few don't bother with it but I don't remember which models they are. (If you print black and white it doesn't print the dot patterns)
