HP LJ3 50 Service Error - Update
Greetings,
I am trying to figure out if the problem is the fuser or the power supply. The two AC leads on the fuser show an open circuit. The two AC lugs from the PS which go into the fuser have ~120V. The +24, +5, & -5 voltages are present on the side port. I take this to mean that the problem is either the lamp or the thermal cutoff electronics.

If you pull out the fuser and look you can figure out how to get into the middle of the fuser and get direct access to the fuse thing. In the middle of the "leading edge". At that stage, you can determine what is open... the lamp filament or the fuse thing. It is a lot of detailed work to replace the lamp, and cost wise, getting a rebuilt fuser is far better for you. I never located a source for spare fuse things, so.... you need to most likely trade in the fuser for a rebuilt one..... or buy another printer real cheap and maybe it has a good fuser.

HP's spare part replacement unit is the entire fuser, which can be removed
easily by unscrewing 4 screws. Companies selling spares for older HP printers have followed suit, usually with a trade-in of the old fuser. HP probably does not sell spares for the LJ III any more...
