SOURCE: 980: Fatal Error

From the Service Manual:
*Service call
980:Error

*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.

SOURCE: Error message: Service Call 980 - Fatal Error

It means a call to OKI will be necessary. Typically, fatal errors are related to internal ROM, or board components that effect the boot process of the printer. When it can't boot - you get this type of message.

Error code: 173
This error code means that the fuser temperature is low. You need to replace either the fuser or the thermistor inside the fuser.

Our OKI C5100 is showing 171:Fatal error. What should we do?


The 171 Fatal error:

Upper Thermistor, State:Open

When an open circuit has been detected in the heat roller thermistor (low temperature)

Check the heater connector and the thermistor connector to make sure they are seated properly. If OK you probably need to replace the fuser.

Hope this helps.

Service Call: 173: Fatal Error


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.
