Oki printer MC860 is displaying fatal error 928. What does this mean

177 is a thermistor problem within the fuser. Just replace the fuser to cure the problem. Remember to replace the fuser with the power off.

Just to confirm that Jeff Hughes is correct. 928 does refer to paper wrapped around the fuser rollers making the thermistor see nothing hence the 928. If there is no paper in the fuser then it will need to be replaced. Remember to turn the machine off when removing or replacing the fuser.

What does "Fatal Error" mean?
Summary: Printer has displayed a "Fatal Error" message. This simply means a problem has occurred requiring you to take action. It does NOT mean that your printer has "died".
Your printer display or status monitor may read "Fatal Error". This simply means a problem has occurred requiring action to clear.
A "Fatal Error" does not mean your printer will "die". Fatal Error explanations are not usually found in the User's Guide or Handy Reference Guide.

RECOMMENDED NEXT STEP: First, try turning off your printer then turning it back on. If this does not clear the message or remedy the problem, check to see if your printer is on a power strip (or not plugged directly into the wall). For testing purposes, be sure the printer is plugged directly into the wall. Often, the issue is power-related.

Second, if the issue persists after this, write down the message (including the 3-digit error code number) and email us at "[email protected]" 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, be sure to write these down also and report them when call or emailing Customer Support.
