Solutions

Quick Diagnosis

If the machine displays code SC543 on startup, the thermistor may be dirty or the heating element may have a disruption. Check if the rear area feels unusually cool after switching the unit on.

Step-by-Step Solution

  1. Turn the machine off completely.
  2. Inspect the fuser area for jammed paper that could be trapping heat.
  3. Access Service Mode (SP Mode) and try to perform the SC reset procedure.
  4. If the error persists, the thermistor requires a manual inspection.

Prevention and Maintenance

Avoid very short print jobs and ensure the unit is connected to a stable power outlet. Perform preventive maintenance on the fuser unit every 100,000 copies to replace worn rollers and thermistors.

When to Call a Technician
