Service Call 020 Fatal Error

We had some pretty bad storms last night, and when I got here this morning, it was showing that error.. I called our local repair place, she said that she didn't have a tech that could work on it, and that usually the fatal errors mean the card is gone and will cost more than the printer is worth to fix it.. Any suggestions??

Re: Service Call 020 Fatal Error

Error 020 is a ROM dimm error, could be as simple as reseating/replacing Rom Dimm or a expensive main PCB, you need to get hold of a oki dealer, contact oki to find closest OKI repair agent.

Fatal Error 121

Hi and welcome to Fixya!
"Fatal Error" on your printer display or status monitor simply means a problem has occurred requiring action to clear. Fatal Error explanations are not usually found in the manual. You can check the list of error codes from the link below:
First, try turning off your printer then turning it back on. If you're still getting the same error message, make sure the printer is plugged directly into the wall. Often, the issue is power-related.
If the problem persists, write down the message including the 3-digit error code number and send an email to "" or call Oki Data Customer Support (1-800-654-3282) for assistance.
NOTE: If you see a series of letters and numbers scrolling across the display after the 3-digit error code, write it down and report them when calling or emailing Customer Support.

Fatal error 020: oki c5450

As far as 020 error is concerned it is the TNY on the controller board. If you take the controller board out (it's the board that the usb/network cable plugs into). You find 2 banks. Ones for memory, the other bank is your prom board they refer to as a TNY.

980: Fatal Error

From the Service Manual:
*Service call

*Error by media
clinging to the fuser

*Media has clung to the fuser.

*Power OFF
Replace the fuser unit.

Suggestion -
Before you replace the fuser, take it out and check for a piece of stuck label, paper, etc. You can spin the fuser roller by turning the gear on the side.

Fatal error

That is a control board error.
i dont think that it would be hard to change out.
but the board price may deter you from fixing it. Considering it about 5 or 6 years old.
here is a list of parts for your printer. I cant find prices for it . you can call Okidata for it.

That is a fuser erron code. Abnormal temperature. You will need to replace the fuser. Sometimes I have sen a buildup of toner on the thermistor. If you can get to it. You can try to clean the toner off. Be careful. Very hot.
