Ricoh Pro C7210x SC672-00 Error: Startup Failure
The Ricoh Pro C7210x SC672-00 error indicates that the main controller board did not respond correctly during the boot cycle. This startup fault means the system cannot communicate with the engine. It is a severe fault that requires checking for power conflicts before assuming major hardware failure.
Common causes
- 1Communication bus failure on the motherboard post-boot.
- 2Unstable voltage delivered by the power supply unit to the controller board.
- 3Corruption in the main controller's RAM memory.
- 4Physical disconnection or oxidation on board communication pins.
Solutions
Quick Diagnosis
The SC672-00 error prevents the machine from passing the splash screen. If fans rotate but the panel does not initialize, the controller is failing in its internal communication.Step-by-Step Solution
- Turn off the machine from the main switch and unplug it for at least 15 minutes to allow capacitors to discharge.
- Remove any connected USB drives or network cables, as faulty peripherals can interrupt the boot process.
- Reconnect the power cable and turn on the unit, ensuring a stable wall outlet connection.
- If the unit boots into Service Mode, check the event logs to identify the triggering component.
Prevention and Maintenance
Use an industrial voltage stabilizer or high-capacity UPS to prevent power fluctuations from damaging sensitive electronics. Avoid non-official USB devices. Keep internal areas dust-free to prevent micro-shorts on the board pins.When to Call a Technician
Repeated SC672-00 errors indicate a physical failure in the BICU (Board Interconnect Unit) or the main controller, requiring original part replacement.Technical Specifications

Frequently asked questions
This is a controller board (Engine/Controller) communication error. It signifies the system failed to complete the boot process.
No, SC672-00 is purely electronic and does not affect consumables or toner quality, though it prevents usage.
If this happens frequently, it indicates an underlying hardware issue that needs professional inspection.
Unplugging is a last resort for total lockups; always use the soft-power button whenever possible.
