A 121.08 Service Fuser error appears in the printer’s operator panel. A paper jam can be found inside the printer right under the fuser.

 NOTE: The error could possible appear during any of these scenarios:

  • The “Media Type” setting of the printer is set to Label or cardstock.
  • The printer just got powered on or was in “Power saver” mode when the print job was sent.
  • The first page is printed immediately after clearing a paper jam.


Recommended solution

Step Action


Clear the error by powering off the device and removing any media that could be stuck in the fuser. See the images below on how to remove the printer supplies and access the fuser area. Power the printer back on after making sure that it is clear from any obstruction.




Heavy or thick media may possibly cause 121.08 error. Check the media that you are using if it is supported by the printer.

See the "Paper and specialty media guide" section of the printer's User's Guide to verify if your media meets all recommendations.




Should error returns after printing some pages, you can try changing the media type setting. Note: Changing the media type to a lighter weight media (a media setting that requires a lower fusing temperature) may reduce the frequency of the error.

Example: If media type is initially set to “labels” or “cardstock”, changing it to "plain paper" can lower the frequency of the error.

Monitor the resulting print quality and error rate after changing the media type setting.




If error returns or if changing the “Media Type” settings compromises the quality of the printout; contact Lexmark Technical Support for additional troubleshooting recommendation.
