  • High toner coverage
  • 120 K page count on (H models, e.g., MX621)
  • 150 K page count on (L&M models, e.g., MX321, MX521)


Upgrade firmware to (FW5), or above. A changed algorithm will automatically change settings in an effort to avoid this fuser-stall situation.

If upgrading firmware is not an option, set the media type to Light, Texture to Smooth and Weight to Light.

Changing media type, texture, and weight:

  1. Navigate to Settings > Paper from the printer or EWS.

  2. Change Type to Light, andthen click Save.

  3. Under Media Configuration, for Media Type – Light, set the Texture to Smooth, and then click Save.



Fuse grade issues might occur if normal or heavy media is used under light smooth media settings. Please ensure to change the media settings to its appropriate values if paper other than light smooth is used.
