Step 3: Inspect and Clean the Thermistor (Most Common Fix)

• Remove the fusing unit from the machine (usually two blue levers).
• Locate the thermistor(s) – typically one center and one edge sensor. They appear as small glass beads on a metal bracket.
• Use a soft, dry cloth or a cotton swab with isopropyl alcohol (91% or higher) to gently wipe off toner residue.
• Do not scratch the glass surface.
• Reinstall the fuser and test.
