The Smart Operation Panel runs its own independent firmware, separate from the main machine's system firmware. An outdated version or a mismatch between the panel and controller firmware can lead to handshake failures over the Flair interface. Newer firmware revisions often contain patches for such communication issues.
: The error can be triggered by a firmware bug related to the energy-saving system. : Update the machine's
When the controller boots, it sends a WHO_ARE_YOU? command to the panel. The panel must reply with its model ID and firmware version within a strict window (typically 15–30 seconds). means the controller received no valid reply or a malformed reply during that window. The controller then shuts down the panel power (via the 5V/12V enable line) and logs SC673-10.
Physical connection issues are a primary hardware cause. A disconnected, loose, or defective controller board harness or a poorly seated operation panel ribbon cable can prevent the main machine from communicating with the panel. This is particularly common after moving the device or during a parts replacement, where a connector might not have been fully locked in place. sc673-10 ricoh error
If the error persists, physical communication lines must be checked.
Restart the machine to rule out an external device interfering with the boot process.
Enter Service Mode (the exact sequence varies by model, often involving the Reset key followed by numbers like 806182 and holding "C"). The Smart Operation Panel runs its own independent
To prevent communication errors like SC673-10 from recurring, implement these best practices:
Disconnect the cables, inspect the pins for damage, and firmly plug them back in.
This error is primarily a handshake failure within the machine's internal networking. Common causes include: : The error can be triggered by a
The Smart Operation Panel itself may have a faulty communication module.

The Ricoh error code is defined as an Operation Panel Flair Communication Error . This specific service code only occurs on Ricoh machines equipped with a Smart Operation Panel (SOP) . It indicates that the communication between the smart panel and the main machine controller—referred to as "Flair communication"—has failed or was never established. Core Causes
Swap out the operation panel harness with a new one to rule out hidden wire breaks.
The main controller board itself may be damaged. Step-by-Step Troubleshooting Guide Follow these steps in order to resolve the issue. 1. Perform a Full Power Cycle (Most Common Fix) A simple restart can fix a "stalled" controller board. Turn off the main power switch on the machine. Unplug the copier from the wall outlet.
This is the most common cause, especially after a firmware update. If the Operation Panel firmware is corrupted or does not match the controller firmware version, the handshake fails. The -10 sub-code is particularly sensitive to timing issues introduced by buggy firmware.
