Solutions

Quick Diagnosis

SC670 is a board communication error. If you hear internal clicking sounds without the screen loading, the control board is likely failing to hand over the startup sequence.

Step-by-step Solution

  1. Hard Power Down: Flip the main power switch to off and disconnect the power cord.
  2. Clear Peripherals: Remove any external USB drives or network cables connected to the unit.
  3. Power On: Reconnect power and switch on the device.
  4. Service Inspection: If the SC670 message persists, a trained technician is required to perform a deeper diagnostics check on the BICU board.

Prevention and Maintenance

Always use an Uninterruptible Power Supply (UPS) to guard against voltage spikes. Never pull the plug while the device is in operation. Periodic firmware updates provided by Ricoh are essential for system stability.

When to Call a Technician

Since this involves internal logic board communications, you should seek support if the error prevents the copier from reaching the 'Ready' screen after a power cycle.
