The UK Guardian reported today the main reason for the difference is that the Detroit scanners were in such poor shape that they were often jamming when a voter put in their ballot papers. It seems that as an election judge retrieved the ballot and ran it through the scanner again, the machines actually tallied those ballot twice. I’m not sure this would constitute an intentional ballot stuffing, although that would be the end result.
They’re only 10 years old and are rarely used.

Normally (at least here in east central Illinois) one the ballot is scanned, it is dumped into a bin which is locked until the polls are closed. It cannot be retrieved because of the locked bin and there would be no way to tell which one it was.
My guess is that the election officials were all of one party and fed more ballots in.
