Common causes

  • 1Power supply failure: Inability to generate stable output voltage.
  • 2Printhead short: Electrical fault within the ink delivery module.
  • 3Surge damage: High voltage spikes causing internal PCB failure.
  • 4Capacitor aging: Loss of ability to store energy within the supply unit.

Solutions

Diagnóstico rápido

The SC302 code warns that the charge circuit is not responding correctly. Why does my Ricoh Aficio SG 3110DNw show error SC302? Typically, this is the result of external power surges or an internal short-circuit affecting the high-voltage supply.

Solución paso a paso

  1. Unplugging: Disconnect the printer from all power sources for 15 minutes.
  2. Environment check: Ensure the printer is plugged into a wall outlet without extensions.
  3. Inspection: Look for any burnt smell or visible damage to the ports.
  4. Power up: Restart the printer to see if the voltage self-calibrates.

Prevención y mantenimiento

Always operate this printer on a surge-protected circuit. Periodic firmware updates can occasionally resolve logic conflicts that manifest as voltage errors.

Cuándo llamar a un técnico
