My highschool was going to pitch this Lexmark 4039 10P because it would cost too much to fix it, so I took it home today, but I couldn't get a service manual or any support for it, so I tore into it. An hour and a half later, I'd corrected the main problem (a stuck fuser assembly, it was grinding plastic gears LOUDLY! :Q), cleaned the piles of toner out of it, learned how to tweak it up, and now I have a fully functional Postscript printer with one used and one brand new toner cartridges. Pretty good haul, eh?
