How much does the paper move when the hammer hits it? even with the padding of the ribbon (and having seen the video clips of it in action - ps. would love to see high-speed closeups if you get a chance) I'm not sure why the paper doesn't tear when the hammer hits it - or if it's a very short distance, does it instead smudge?
- cbhl 2y agoI think the paper gets sandwiched between the hammer on one side and the drum on the other side. This would be not too dissimilar to how a typewriter would have worked, I think?
- userbinator 2y agoLess than 100 thou, I think. It's also a very rapid process, so the drum would have barely moved meanwhile.
- kens 2y agoYou'd think that hammering the paper against the spinning drum would result in a blurry mess at best, but the hammers are fast enough that it works. It's the same principle as a chain printer such as the vintage IBM 1403, where the chain is zipping along at 90.3 inches per second when it gets hammered.
