I’m sure no one would be concerned by this at all: certain Xerox machines in certain scanning modes make a marvelously specific compression error. A number 6 might become an 8, or a 1 is turned into a 2. Photocopy a page with a column of numbers, and who knows what you might end up with.
This could not possibly be a problem for anyone, could it? At least it doesn’t convert 4,540,000,000 into 6,000. That would be worse.
