Sc673-10 Ricoh Error ((new)) May 2026

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.

Firmware Update: Outdated or corrupt firmware is a common cause for SC673 errors.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

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. sc673-10 ricoh error

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

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. The Ricoh SC673-10 error code typically indicates a

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. Keep scanner glass and reference strip clean

SOP Unit: The Smart Operation Panel itself may have a faulty communication module.

Part 1: What is SC673-10? Understanding the Error

Ricoh’s SC (Service Call) codes are designed to protect the machine from further damage. An SC code halts operation and requires a technician-level intervention.

Q: How much does a technician cost to fix SC673-10?

A:

What does this mean in plain English?

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.

Fix D: Controller Board Replacement

When all else fails, and you have confirmed the cable and panel work on another machine, the controller board (BICU / Controller PCB) is likely at fault.

Model-Specific Notes on SC673-10

While the SC673-10 error appears across many Ricoh platforms, it is most prevalent on:

| Series | Common Models | Specific Cause | |--------|---------------|----------------| | Ricoh IM C Series | IM C2000, C2500, C3000, C3500, C4500, C5500, C6000 | Faulty panel firmware v1.10 to v1.15; resolved in v1.20+ | | Ricoh MP 6503/7503/9003 | MP 6503, 7503, 9003 | Loose FFC due to design of tilting mechanism | | Ricoh Pro Series | Pro 8100, 8200, 8300, 8310 | Conflict with JavaTM applets or embedded SDK applications | | Ricoh SP Series | SP 5300DN, 5310DN | Corrupt NVRAM on operation panel itself |

Always check Ricoh’s official Technical Service Bulletin (TSB) for your specific model. A TSB may indicate a known hardware revision or a simple jumper setting change that resolves SC673-10 without part replacement.
