Sc673-10 Ricoh Error

A recent update failure or corrupted system software prevents module synchronization.

Once in SP mode, use the number keypad to navigate to and enter SP5-748-201 . This setting may also be listed as SP5748-201 .

In cases where the error persists after all cabling and software checks, a failing hardware component is likely the culprit. The controller board is the central processing unit of the main machine. If it is faulty, it cannot process the Flair communication protocol. Alternatively, the Smart Operation Panel itself may have become defective, failing to initiate or respond correctly to the communication sequence.

The main controller board itself may be damaged. Step-by-Step Troubleshooting Guide Follow these steps in order to resolve the issue. 1.
