The figure after the K drum Life tells you how much life there is left on the BLACK (K) drum. C indicates Cyan, M indicates Magenta and Y indicates Yellow.

Go to the USAGE MENU and look at the K DRUM LIFE setting. This will be a 2 digit percentage value. As you have just seen the message appear this will mean that the drum life remaining is ....whatever the 2 digit value displays.

The life expectancy of a drum is approximately 15,000 pages.

I had a paper jam and removed the jammed papers. The paper jam cleared and then the Fatal Error 980 appeared. OKI C5500 printer

Error 020
When an error has occurred in the controller board (CU) or the program Rom.




Resolution:
Replace the Rom Dimm, see chart below for the correct part number. If the Rom Dimm does not correct the issue, then replace the (CU) controller board. Please refer to the service manual for (CU) part number depending on the printer revision

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.
