I used one in the early 1980s but I never had to repair it. It was, as Tony and others have mentioned, electrolytic, not thermal. I don't know the details of the process either, but I remember the wet wick and having to wait for the paper to dry. It was a PITA, but being able to do screen shots was amazing. The only other terminal I worked with that could do that was a Tektronix storage scope terminal (4010 or 4014, IIRC). The Tek printer wasn't built-in, but it did take a scan of the live screen, so that was similar. The paper was silver-grey and I remember it coming out wet too. Everything else I worked with was either thermal or dot-matrix impact, and could only capture text as it arrived at the terminal, not a screen image. -ethan
