Common causes

  • 1BCU fault: Main board logic communication error.
  • 2GW Controller: Controller board failure.
  • 3Wiring: Loose connection between boards.
  • 4Voltage: Power surge damage.

Solutions

Quick Diagnosis

The SC670-00 is an internal connectivity issue. Why does my Ricoh MP C6503EX show SC670-00? Usually timing conflicts between boards or power surges affecting electronics.

Step-by-Step Solution

  1. Restart: Power down, wait 30 seconds, and power up to trigger bus re-initialization.
  2. Check Connections: If technically capable, verify board power/data cables are secure.
  3. Professional Help: If persistent, BICU or print controller board may need replacement.

Prevention and Maintenance

Always connect to stable power sources. Keeping the interior clean helps prevent micro-shorts caused by dust on boards.

When to Call a Technician

Hardware failure. If a power cycle doesn't fix it, internal electronics require professional diagnosis.
