Confused Xerox copiers rewrite scanned documents, expert finds (2013) (opens in new tab)

(2013). The whole ordeal lead to a quite legendary presentation by David at CCC (german, no captions, live translation available but pretty bad): https://youtu.be/7FeqF1-Z1g0

If you speak german and haven’t seen this yet, watch it, this is a classic. His talks are all entertaining and interesting.

Jbig2 sounds like a bad option for a photocopier. They should not attempt to parse what they're copying.

From 2013 but yeah, what an unexpected thing to happen from a copy machine!

To me, this is why the whole pinch-to-zoom debate of the recent trial was legit. You really don't know what changes to pixels technology is making unless you look at the code.
