I am running Microsoft XP and have a HP 1012 laser jet printer. It has been acting up lately. All 3 lights are lit up, which in the manual means "fatal error" with the machine itself. I can turn the printer off and sometimes it will run ok for a couple of prints and then goes back to all 3 lights lit up again. Oh, by the way, they are solid not blinking. I have uninstalled and reinstalled drivers and nothing changed. Anyone know what this means? Do I need a new laser jet or just some parts? Help!!
