LaserWriter IIg Cannot Reach Temperature Error

[Johnnya101]

Turned on my LaserWriter II for some work prints, and discovered the Paper Jam and Paper Out lights were flashing! I opened printer utility and found that it was flashing a temperature related error. Opening the printer door, I noticed there is no heat like usual coming from the fuser. I jumped pins 4 and 22 to bring it into diagnostics mode, and was greeted by the ready light and toner out solid, and the last two flashing, which according to the chart means bad fuser.

So... I would hope I can use a typical HP LaserJet II or III fuser with this?

Would this work?

Or is there a way to refurbish the original? I'd rather reuse it.

Print engine has about 67k pages, logic board 180k. Apple usually calls for replacement at 100k. Guess age + storage conditions might have something to do with it as well...

If I rebuild it, what part actually failed?

Strange looking bulb, think it's toast.
Think I'll try and get a new bulb.
No continuity at all.

LaserJet II/III fusers work fine. Should be readily available and not too expensive.

Managed to find a LaserJet II/III parts lot with a refurbished fused, toner, gear trains, cables, Corona assemblies and more, so I'll just swap in a new fuser.

For the old one, at some point I'd like to replace the bulb. What is the correct model number for it? I see two different bulbs in ebay, ones a 100 volt, ones a 200 volt? RH7-4024-000 vs RH7-4025-000?
