Ricoh SP 3710SFw Error SC670: Startup Failure

Ricoh SP 3710SFw error SC670 happens when the internal controller board cannot verify a successful handshake with the system modules during initialization. This prevents the printer from finishing the power-on process. It is a logic board communication fault that requires a specific sequence of tests to troubleshoot. This model is engineered for high reliability in office settings.

Common causes

  • 1Logic board (BCU) electronic failure during startup.
  • 2Firmware corruption following an interrupted update process.
  • 3Short circuit in communication ports caused by electrostatic discharge.
  • 4Internal loose ribbon cables between board sections.

Solutions

Diagnóstico rápido

The SC670 error is essentially a startup timeout. If your machine stays stuck on the boot screen or displays the code immediately upon power-up, it means the internal system has failed to sync.

Solución paso a paso

  1. Static Discharge: Power off and disconnect every single cable for 20 minutes.
  2. Minimum Power Test: Plug only the power cord and turn the device on.
  3. Peripheral Isolation: If the device works, reconnect your network or USB cable to check for faults.

Prevención y mantenimiento

Use a surge protector to shield the sensitive electronics from power irregularities. Avoid abrupt shutdowns that can corrupt the system memory or firmware.

Cuándo llamar a un técnico

If the reset does not clear the error, the logic board has suffered a failure and must be repaired or replaced by a professional.

Steps to follow

  1. 1

    Static Discharge

    Turn off the printer and disconnect all cables, including USB and network cables, for 20 minutes.

  2. 2

    Startup Test

    Connect only the power cable and turn on the unit without any additional peripherals.

  3. 3

    Verification

    If the printer starts correctly, reconnect cables one by one to determine if a specific peripheral is causing the fault.

Frequently asked questions

The SC670 signifies an internal communication error (BCU/BICU) during the power-on self-test, indicating that the main board cannot talk to other system modules.

This is a complex internal error, but performing a hard reset while disconnected from all peripherals is the best DIY attempt before consulting support.

No, this is an electronic hardware fault; the toner cartridge is not involved in the logic board's startup sequence.

Always connect your printer to a high-quality surge protector or UPS to minimize voltage spikes that can damage sensitive logic boards.
