Ibm IBM Selectric I

IBM type 4029-022 error 922 service

I saw a post where someone had this error on a different IBM model. The post said the error was due to a fuse. Do I have the same problem with my model? Thanks
The error is a fuser failure. This can be caused by a bad lamp or the thermal fuse, both of which are inside the fuser.

So you're telling me I need to call IBM? I know nothing about working on printers. Is it an easy fix?

Thanks a lot

Eli this is not very hard to repair....but does require a little mechanical ability (Not meaning to affend you). It'd probably be better for you to call around locally for someone who can repair it (not IBM). .... You have to remove several parts to get the fuser unit out.

Thanks Jim, are there any detailed instructions I can get ahold of online that would help me?

The thermal fuse is under the plastic cover on top of the fuser. Only 2 screws holding the cover on. You'll need a meter or continuity tester to check the fuse. Might be able to get one at Radio Shack. If you need a lamp, we stock them. Don't have any replacement videos or printed instructions.

As Moe pointed out, the fuse is easy to test without removing the fuser. When you get the parts you need, email me and I'll see if I can dig up an exploded diagram. IBM(Lexmark) doesn't cover fuser disassembly in their service manual but it's really not complicated. I'm willing to help in any way I can.

Thanks a lot guys. I am going to check it out.

Are you talking about the plastic cover on top of the printer or the one on the side? What does the fuser look like?

thanks a lot

If you open the lid as if to change the toner cartridge, the fuser is the black rectangular box in the front. You'll see the 2 screws on top of the black plastic cover.

Have 922 service error. Removed 2 screws on top fo the fuser.
See a blue wire running across the top of the fuser. In the middle is a 2 inch long component inside a tan clear plastic sleeve. Is this the thermal fuse? Do you have to remove it to test it? Have DVM. The sleeve looks like it is mounted to the metal frame with small plastic studs going thru the frame. Do I have to remove it to test it? What exactly do I need to replace it?
Someone mentioned Radio Shack. Last visit here was with salespersons completely clueless as to electronic componets.
Where are the thermister and lamp? Don't see them.

Been at least 10 years since I worked on one. The thing on top is the thermal fuse. I seem to remember them being the same as the thermal fuse in a coffee maker. That's what I used to buy to replace them. From what I remember, you don't have to remove it to test the resistance. If I remember correctly, there was a connector over on the back left that you could check lamp resistance through. Radio Shack = Clueless. Also extremely expensive. I would never send anyone there.

Saw several on Ebay. 172, 210 degrees. What temp should I get if I replace the thermal fuse in my IBM 4029

Saw in another post you said 172 degrees for the thermal fuse. Is that Centigrade?
On Ebay they list them in Centigrade not Farenheight.

Of course that's Centigrade. 172 degrees F isn't hot enough to boil water, much less melt toner.

I have an error code 941. I've googled for several days now and I found it for lexmark saying it's a laser issue. If anyone has knowledge on this unit and knows the part(s) I need to replace and where to find them your help will really help me out. Thanks in advance =)

The laser scanner unit sits on top of the printer. I haven't worked on one of those beasts in at least 10 year. If I remember, it was a real pain to replace the scanner assembly. That's assuming you can even find one for it. That model is about 20 years old. I don't know why you would even bother trying to fix it. - moe
