This isnt really MAC related but the macidiots laserjet 5m (the M is the postscript model) went through some open heart surgery to replace the paper input unit. This printer is a bit like Triggers’ broom in that it is really only the chassis that is original as I have replaced far too many parts on it. At least now the printer no longer jams every third page and the Mac’s (and PC’s) can print again!
