In some Ricoh models, a dead lithium battery on the controller board (specifically the NVRAM battery) can cause boot issues. If your machine is older (5+ years), this battery may need replacing. However, this usually throws different codes, but it is worth noting.
First, let's decode the nomenclature.
"Operation Panel Communication Error (Initial Communication Failed)."
The SC673-10 Ricoh error is intimidating but rarely signals catastrophic hardware failure. In our experience, over 70% of cases are resolved by updating firmware or reseating the Flat Flex cable. Only a small percentage require board-level replacement.
By understanding that this error is fundamentally a handshake failure between the controller and the operation panel, you can methodically isolate the cause—whether it’s software, cabling, power, or hardware.
Quick Recap Checklist:
Bookmark this guide, keep a spare FFC cable in your parts inventory, and always check for Ricoh TSBs before ordering expensive components. With patience and a logical workflow, you can conquer the SC673-10 error and restore your Ricoh MFP to full productivity.

The Ricoh SC673-10 error code typically indicates a communication error between the controller and the operation panel (Smart Operation Panel). This happens when the controller fails to receive a response from the panel within a specified timeframe after startup. Quick Troubleshooting Steps
Power Cycle: Turn the main power switch off, wait at least 30 seconds, and turn it back on. This often clears temporary communication glitches.
Check Cables: Ensure the connection cable between the operation panel and the machine's controller board is securely seated and not pinched or damaged. sc673-10 ricoh error
Firmware Update: Outdated or corrupt firmware is a common cause for SC673 errors. Check Ricoh Support for the latest firmware updates for your specific model. Advanced Service Mode Reset
If the error persists and prevents normal operation, you can attempt an SC reset through the Service Program (SP) Mode.
Access Service Mode: On most modern models, press Reset (Yellow) -> 806182 -> press and hold Clear (C) or Stop until the menu changes.
Execute Reset: Navigate to System SP -> SP-5810 (SC Reset) and execute the command.
Restart: Power the machine off and on again to finalize the reset. Likely Component Issues In some Ricoh models, a dead lithium battery
If the above steps do not work, a hardware component may need replacement:
Operation Panel: The physical panel or its internal board may be faulty.
Controller Board: The main board may have failed to initialize communication.
SD Card/Storage: In some models, a corrupt system SD card can prevent the panel software from loading properly.
