Xerox scanners randomly alter numbers in scanned documents (2013)
Even though this happened a long time ago, whenever I hear or think about it, I am a mazed that it didn't put Xerox out of business, or at least hurt a little more. After all, some big players were already doing digital archiving at the time. :-/  BTW, the CCC had a pretty neat presentation at that time as well: https://www.youtube.com/watch?v=c0O6UXrOZJo
