Solutions

Diagnostic

The SC544 error triggers when the thermal sensor detects unusually high temperatures. Check if the error occurs right after a long print job or immediately after restarting following a paper jam.

Troubleshooting steps

  1. Switch off the machine and unplug it to allow natural cooling.
  2. Verify the fuser unit fan is not blocked by lint or dust.
  3. Wait 15 minutes before attempting a restart.
  4. If the code persists, contact a specialist to check the power board triac.

Prevention and maintenance

Clean air vents monthly with compressed air. Do not operate in enclosed, poorly ventilated spaces, as this accelerates internal overheating.

When to call a technician

The SC544 is an electrical safety issue. If cooling steps do not resolve it, an electronic component is likely shorted and requires professional attention.
