"922 SERVICE" Error, IBM 4029 and not the fuse, Moe plz check your email.

Pretty much what it says on the tin. I have an IBM 4029 that almost certainly needs a fuser, since the two thermal fuses soldered together in series (!) have continuity across them both. Moe, you have an email from me ([email protected]) since you popped up in other threads as maybe having parts for my machine -- the email has not been answered -- I thought I'd check and make sure I wasn't missing any sort of news there.

I don't use that email anymore. Haven't worked on one of those in over 5 years. Did you check continuity across the lamp? They are still available on the internet.

Sorry, I didn't see this till now. I did not check the lamp itself; I assumed it was either the lamp or the fuse. Could it be anything other than those two?

That gmail account I mentioned is mine ;) sorry, I wasn't clear -- the email address I sent to is [email protected]

Don't use it. 99% it is the lamp.

Power supply. Never changed one for that.

A 922 error is created by an open ac circuit(lamp circuit) on the fuser. the t520 t 522's have lamp holder problems that allow arching from the ill fitting metal contact to the end of the heating bulb. it is not uncommon for the end of this contact to be cut completely in half by the arching causing the 922 error. there are 4 components making up this circuit #2 lamp holders a thermal fuse and the bulb it self. percentage wise for this arching causing this failure is really close to 99.5% of the time. this damage is clearly visable if you remove one of the lamp holders.
