Oki is forcing you to buy a new fuser. If fuser roller, film and thremistors are still in perfect shape, reset is possible with new OEM FB fuse

Oki c5650 in Engine diagnostic mode can't find NV Ram need to reset 980 fatal error code -sheet of paper got wrapped round Image drum need to reset it

You cant find the reset because there is not one. OKI do not use resets to cure errors. Yes a 980 is paper wrapped around the hot or pressure rollers in the fuser. Normally you just take out the fuser and remove the paper and it will start working. However this MUST be done with the power OFF. So it should be a case of just turning it off and removing the jam and refitting the fuser and turning it back on. If the error is still there then alas a new fuser is require to get it going again. You may be able to buy a fuse from suppliers on the net, fit it and that will do the reset without the need of buying a fuser.

OKI C330dn Call Service fatal Error:980

That particular error indicates a fuser failure. Try turning off the printer and re-seating the fuser. If this does not clear the message then the fuser needs to be replaced. With such a low number of prints warranty should cover it.

I had a piece of paper wrap around the fuser of my Oki C5650 printer. I have removed the paper (all of it.), but now it is displaying a 980 Fatal Error code. What do I do now?

I just had a service call with a 980 error. i removed the paper wrapped around the fuser roller but the error persisted. The only thing that cleared the error was to replace the fuser. I am not sure why but the fuser was shot after it had the paper wrap inside it.

There is no reset to clear the error. The only fix was to replace the fuser.
