misbehaving Xerox scanners/photocopiers (old news) Show more
Today I learned that in 2013, a bug was discovered in a whole host of Xerox scanners and photocopiers that caused them to mangle printed numbers with no warning and no clear indication that anything is wrong: http://www.dkriesel.com/en/blog/2013/0802_xerox-workcentres_are_switching_written_numbers_when_scanning
As far as I can understand, the scanners use a lossy image compression algorithm that detects groups of similar chunks of images, saves one of them, and uses that one chunk for every place any of the similar chunks would appear ... and frequently decides 6s are similar to 8s. And, in one case, several boxes on a construction plan are similar enough that the entire numbers can be replaced.
And the way the numbers are replaced, nothing looks out of the ordinary unless the exact numbers in the document are compared digit by digit. There are no unusual artifacts in the image and kerning is correct.
Computers are horrifying, even in places that don't seem like they should be computers.
