Hmm. It looks to me like the metal with the black goo on it (which is
scraped off with a razor in the video) once had a piece of thin foam
glued to it.
Like many things made out of that type of foam, (i.e. keytronic
keyboards, and the anti-noise foam inside certain dec, sun, and other
older machines), the foam has turned into sticky goop after a number of
years (and probably exposure to ozone inside the printer), causing the
solenoid to stick.
Just a guess, since I don't have one of those nearby to take apart.
