SC673-10 is a critical hardware error that rarely resolves itself without intervention. While a simple power cycle or cable reseat is the most cost-effective first step, technicians should be prepared to replace the Engine Control Board or Main Controller Board if the error is persistent.
The Ricoh error code is an informative status code rather than a fatal hardware failure. It typically indicates a communication time-out
between the controller and the operation panel, or a delay in the startup sequence Meaning of the "Informative Feature"
In many recent Ricoh models, this specific sub-code acts as a notification that the machine's "Smart Operation Panel" did not receive a response from the controller within the allotted time during startup or recovery from energy-saving mode. Common Causes & Fixes Energy Saver Settings
: The error can be triggered by a firmware bug related to the energy-saving system. : Update the machine's
to the latest version, as Ricoh has released technical bulletins specifically to correct SC673-10 occurrences. Startup Delay
: It often occurs if the operation panel finishes its boot sequence before the main controller is ready.
: Perform a "soft reset" by turning the main power switch off, waiting 60 seconds, and turning it back on. Communication Interruption
: Potential issues with the USB communication path or the internal flash memory.
: If the error persists after a reset and firmware update, a technician may need to check the internal USB cables or the Controller (CTL) board.

The SC673-10 Ricoh error is a specific service code that appears on Ricoh printers and multifunction devices (MFDs) equipped with a Smart Operation Panel (SOP). Classified as an "Operation Panel Flair Communication Error," it indicates a breakdown in communication between the main controller and the operation panel's monitoring service. What Causes the SC673-10 Error?
This error is primarily a handshake failure within the machine's internal networking. Common causes include:
Failed Monitoring Service: The "Monitor Service" application on the Smart Operation Panel performs an abnormal operation or fails to respond.
Controller Issues: The main controller (CATS module) does not see the required response from the operation panel.
Physical Connection Failures: Loose or disconnected harnesses (cables) connecting the operation panel to the controller board. Some technicians have specifically noted that low-quality USB cables used in certain models can cause these intermittent drops.
Slow Response Times: A malfunctioning controller board that is too slow to respond to the panel's notifications.
Incorrect Service Settings: Specific software settings in the machine’s internal Service Program (SP) mode might be disabled. Step-by-Step Troubleshooting Guide sc673-10 ricoh error
If your Ricoh machine displays SC673-10, follow these steps to resolve it: 1. Perform a Main Power Cycle
The first and most effective response is to restart the device. Turn the Main Power Switch to OFF.
Wait at least 30 to 60 seconds to ensure all capacitors are discharged.
Turn the power back ON and wait for the system to initialize. 2. Check the Smart Operation Panel (SOP) Settings
In some cases, the error occurs because the "Cheetah Panel Connect Setting" is not enabled.
Enter Service Mode (the procedure varies by model; often it involves the [Reset] + + [0] + [7] keys or a sequence on the touch screen).
Navigate to SP5-748-201 (OpePanel Setting: Cheetah Panel Connect Setting).
Ensure the value is set to "1: Connect." If it is set to "0: Not connect," change it and restart the machine. 3. Inspect Physical Connections
If power cycling doesn't work, the issue may be hardware-based.
Verify the Harness: Check if the communication harness between the operation panel and the main controller board is loose or damaged.
Check the USB Cable: On certain compact models like the MP 305+, the internal USB cable connecting the SOP can fail and may need replacement with a higher-quality cable. 4. Advanced Hardware Replacement
If the error persists after checking settings and cables, professional service may be required to replace:
Controller Board: A malfunctioning controller board can prevent stable communication.
Hard Disk Drive (HDD): While not listed in all manuals, some technicians have found that a failing HDD can cause communication timeouts that trigger SC673-10.
SOP Unit: The Smart Operation Panel itself may have a faulty communication module.

The first step is a hard reset to clear any temporary communication glitches: the main power switch. the power cord and wait for 60 seconds Plug it back in and restart the machine. Draft Blog Post
Title: How to Fix Ricoh Error SC673-10: Smart Operation Panel Issues If your Ricoh multifunction printer (MFP) is displaying the
error code, you’re likely staring at a frozen Smart Operation Panel. This specific code indicates a communication failure
between the control panel and the printer's controller board.
While it sounds technical, many users can resolve this without a service call by following these troubleshooting steps. 1. The Hard Reset (First Response)
Sometimes the "Flair communication" signal simply times out. A full power cycle can often re-establish the link: Power down the device using the main switch.
Disconnect the power cable from the wall for at least one minute.
Reconnect and restart. If the error clears, it was likely a temporary software hiccup. 2. Adjusting SP Mode Settings
If the error persists, the system might have the wrong configuration for the panel type. Technicians often check Service Program (SP) Mode
settings to ensure the panel is "connected" in the software: Target Setting: SP5-748-201 (OpePanel Connection). Required Value: Ensure this is set to "1" (Connected)
. If it has reverted to "0," the controller will not "look" for the Smart Panel, triggering the SC673-10 error. 3. Check for Loose Cables
Since this is a communication error, physical connectivity is a common culprit. If you are comfortable opening the side panel (or have an IT tech do so), verify that the USB and power cables
connecting the operation panel to the controller board are seated firmly. 4. When to Call a Technician
If the steps above don't work, the issue may be hardware-related, such as: Controller Board A defective Smart Operation Panel
Voltage fluctuations in your office that have damaged the internal circuitry.
Start with a power cycle, check your SP settings, and if all else fails, contact your local Ricoh service provider for a board inspection. on how to safely enter for your specific Ricoh model? If the machine boots into the Service Mode
Ricoh error code SC673-10 indicates a communication failure between the Smart Operation Panel and the main controller, often resulting from disabled SP settings or controller malfunctions.

and select "Execute" to clear the logged error from the system memory. If the error persists after these steps, the controller board may need to be replaced, or a firmware update may be required to stabilize the communication link. button sequence to enter service mode for a particular Ricoh model?
Specifically, this code indicates a Hard Disk Boot Error. When you turn on the machine, the controller attempts to load the operating system from the HDD. If the drive isn't spinning, isn't connected, or has corrupted data, the boot process halts, and the machine throws this code.
Common causes include:
Warning: This will erase all stored address book data, user settings, and fax logs. If the connections are tight but the drive is corrupted, you may need to format the disk.
⚠️ Warning: Turn off the printer and unplug the power cord before disconnecting any internal cables. Wait at least 30 seconds for capacitors to discharge.
You can perform the following steps safely. Note: Opening covers may void warranties on leased machines—proceed with caution.
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 the machine boots into the Service Mode (often by holding specific keys like "Clear Modes" > "107" > "Stop/Start" for older models, or via the settings menu on newer ones), check the firmware version.
