Solutions

Diagnóstico rápido

This error is usually displayed on the control panel as an 'SC' code. Ensure there are no paper jams in the rear output tray, which could be trapping heat and triggering a sensor fault.

Solución paso a paso

  1. Turn off the printer and unplug it for at least 10 minutes.
  2. Ensure the power cable is connected directly to a dedicated wall outlet.
  3. Inspect the fuser entrance for debris or stuck sheets of paper.
  4. Power on the device; if the code reappears immediately, the hardware fault is likely permanent.

Prevención y mantenimiento

Use original Ricoh toner to prevent toner buildup on the fuser sleeve. Avoid overloading the paper tray with thick, incompatible media that may cause jamming in the thermal assembly.

Cuándo llamar a un técnico

Since this error involves high-voltage and high-heat components, professional servicing is required to replace the fuser or sensor modules.
