Sc673-10 Ricoh Error 99%

Before the error code permanently locks the machine, you might observe one or more of the following symptoms:


The panel itself contains a small embedded computer (running Linux or a proprietary RTOS). If this board fails, it cannot respond to the controller’s handshake request.

If you want, tell me the exact Ricoh model number and whether any recent service was performed; I can provide model-specific service-mode steps and part numbers.

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Firmware Update: Outdated or corrupt firmware is a common cause for SC673 errors.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. sc673-10 ricoh error

SD Card/Storage: In some models, a corrupt system SD card can prevent the panel software from loading properly.

Ricoh SC673-10 error is a specific communication error typically occurring between the controller board and the operation panel, often triggered by processing high-volume jobs or specific user actions during job execution. Error Overview Definition

: SC673-10 is classified as a communication error where the operation panel keys may become unresponsive, or the device fails to process user authentication logouts. Common Trigger Conditions Performing a with a large volume of originals. Pressing the "Reset" key or accessing the "All Job Stop" screen immediately after a large job. Potential freezing issues within the Quick Scan app

when previews are displayed simultaneously with data storage. Troubleshooting & Remediation

Technical documentation indicates this is primarily a software/firmware bug rather than a hardware failure in many cases. Firmware Update

: This is the primary solution. Ricoh technical bulletins (such as for the

series) list SC673-10 as a "symptom corrected" via firmware updates. Check for the latest updates using the RICOH Firmware Update Tool or via the Application Site on your device's home screen. Basic Power Cycle : If the panel is frozen, perform a "Hard Reset": Turn off the machine and unplug the power cord for 60 seconds to clear the temporary memory. SC Reset (Service Mode)

: If the error persists after a restart, a technician may need to clear the SC code in Service Program (SP) mode: Enter SP mode (typically Reset + 107 + Clear/Stop Navigate to System SP > 5810 (SC Reset) and execute the reset, then restart the machine. Hardware Check : If firmware does not resolve the issue, inspect the USB or communication cables

connecting the operation panel to the main controller board for loose connections. Prevention

Avoid interrupting high-volume copy jobs with rapid "Reset" commands before the system has finished internal data processing. Ensure that System Auto Reset

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: Before the error code permanently locks the machine,

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.

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 The panel itself contains a small embedded computer

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.

Here’s a draft of content explaining the SC673-10 error on a Ricoh copier or printer, including possible causes and solutions. This can be used for a troubleshooting guide, service bulletin, or internal documentation.


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.

Device Category: Ricoh / Savin / Lanier Multifunction Printers (MFP) Error Type: Hardware/System Error Severity: High (Device Disabled)


If you are staring at a frozen Ricoh copier screen displaying the error code SC673-10, your machine is trying to tell you a specific component has failed. This error essentially means the controller board cannot communicate with the Hard Disk Drive (HDD) during the startup (boot) process.

While "Hard Disk Failure" sounds intimidating, this issue is often fixable without calling a technician, provided you are comfortable with a few basic troubleshooting steps.

Here is a breakdown of what causes SC673-10 and how to resolve it.

Before assuming the drive is dead, check the physical connection.
