Xerox, incorrect scans and copies

Recommended Posts

I visited a small 3 people metal working company this week and they copied the contract. I saw an ancient Xerox and asked if they updated it. I got just a puzzled look. The old data compression software in the Xerox had a bug which may result in wrong numbers on copies. Our company got a warning years ago from the company where we leased the machines and we paid students to mark all copies as possible wrong using the not updated compression.

In 2015 JBIG2 compression and similiar ones were forbidden in Germany.

The German site even mentions that the talk about Obama's birth documents could be because they were copied with a Xerox.
