  • 2Fuser heating lamp reaching end-of-life.
  • 3Poor contact in fuser connectors.
  • 4Thermal overload from incompatible paper media.

Solutions

Quick Diagnosis

This error typically follows power surges or severe paper jams. Check the display for additional "Heat Roller" or "Fuser Jam" notifications, which confirm the fuser unit is the source.

Step-by-step Solution

  1. Power off the printer and disconnect it from power.
  2. Access the fuser assembly using the blue side lever.
  3. Carefully remove the unit and clean the sensors using a lint-free cloth.
