Solutions

Quick Diagnosis

The device locks and shows the SC545 code. This occurs when the thermistor fails to signal the fuser heater to stop, leading to a thermal runaway detection.

Step-by-Step Solution

  1. Turn off the printer and disconnect from the power supply.
  2. Allow the internal heater to cool down for at least 20 minutes.
  3. Connect directly to a stable wall outlet.
  4. Power on; if the SC545 persists, the internal sensors are locked.

Prevention and Maintenance

Use a surge protector to guard against voltage spikes. Avoid long, continuous print jobs. Genuine Ricoh toner cartridges ensure cleaner fuser operation, preventing pigment buildup.

When to Call a Technician

If the error code returns after the cooling period, the fuser thermistor or heating element has failed and requires professional repair.
