Sc673-10 Ricoh Error <Windows OFFICIAL>
When you turn on the Ricoh MFP, the main Controller Board (the “brain”) and the Operation Panel (the “face” with the touchscreen) perform a handshake. They exchange data packets to confirm they are compatible and functioning.
The SC673-10 error occurs when the Controller Board sends a startup signal to the Operation Panel, but the Operation Panel does not respond correctly within a specific timeout period. The -10 sub-code typically indicates that the failure happened during the initial boot sequence before the panel’s operating system fully loads.
Internal cables often vibrate loose over time or during transport.
On some Ricoh models, you can force a panel firmware reload:
If you replaced the operation panel with a used unit from a different model, or if a technician flashed the wrong panel firmware, the controller will reject the panel, showing SC673-10.
If you are a technician, office manager, or IT administrator responsible for maintaining Ricoh multifunction printers (MFPs), you know that error codes are an inevitable part of the job. Among the more perplexing and frustrating diagnostic codes you may encounter is the SC673-10 Ricoh error. sc673-10 ricoh error
This error typically appears on newer generation Ricoh devices (such as the Ricoh IM series, MP 6503/7503/9003 series, and some color production units). When this code appears, the machine usually becomes non-responsive, displaying the error message on the Operation Panel (OP) and refusing to copy, print, or scan.
In this detailed guide, we will break down exactly what SC673-10 means, its root causes, step-by-step troubleshooting procedures, and long-term prevention strategies.
If all else fails—firmware is current, FFC and panel test good, and power is stable—replace the Controller Board. Before swapping, note that the new controller may require:
SC673-10 = Panel brain is alive but not speaking correctly.
Start with firmware recovery via SD card (success rate ~50%). If that fails, replace the entire operation panel assembly – 90% of remaining cases solved. Controller board replacement is rarely needed for -10 (unlike -11 or -12 subtypes).
If you provide the exact Ricoh model (e.g., IM C3000, MP C6004ex), I can give the precise SP codes and firmware filenames for that series. When you turn on the Ricoh MFP, the
The SC673-10 error on Ricoh devices is a communication failure between the Smart Operation Panel (SOP) and the main controller (CTL) during startup. This specific sub-code indicates that "Flair" communication—the link used by smart panels—is not reaching the panel. Core Causes
Disabled Panel Settings: The Service Program (SP) mode might have the smart operation panel connection disabled (set to "0").
Controller Issues: A malfunctioning controller board or sudden voltage fluctuations can disrupt communication.
Connection/Hardware Latency: The CATS (controller) module does not receive a response from the service control module (the panel) within the expected timeframe. Troubleshooting Steps Perform a Hard Power Cycle: Turn off the device using the main power switch.
Unplug the power cord for at least 60 seconds to clear residual charge. Internal cables often vibrate loose over time or
Plug it back in and restart to see if the communication link re-establishes.
Verify SP Mode Settings:If you have technician access, check SP5-748-201 (OpePanel Setting: Connection to Cheetah/Smart Panel).
If the value is 0 (Not Connected), change it to 1 (Connect). Check Physical Connections:
Ensure the USB/communication cables connecting the operation panel to the main body are firmly seated and not damaged. Reset SC Codes:
Enter Service Mode and navigate to System SP > 5810 (SC Reset). Execute the reset and restart the machine.

A failing controller board (motherboard) can have damaged communication ports (LVDS or USB signal lines). This is rarer but happens after a power surge.
