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

(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.

Very tangentially related: did you know that photocopiers recognize a particular pattern of circles to detect if someone attempts to copy a banknote?
