Solutions

Diagnóstico rápido

If the printer hangs at the splash screen or displays SC670 instantly after you power it on, the internal system components are unable to 'talk' to each other.

Solución paso a paso

  1. Power down and unplug the unit for 10 minutes to clear the RAM.
  2. Disconnect all peripherals (USB/Ethernet) to rule out external interface interference.
  3. Verify internal components by ensuring all internal boards are securely seated (advanced users only).
  4. Power on the printer in isolation to test the core boot sequence.

Prevención y mantenimiento

Always keep your printer firmware up to date through the official Ricoh portal. Avoid power outages or manual power-offs during firmware updates to prevent data corruption.

Cuándo llamar a un técnico

SC670 is a board-level fault. If a power cycle does not solve the issue, the main controller board is likely defective and requires professional replacement.
