A failing Controller Board (also called the Main Board or BICU board) may send incomplete or incorrect initialization signals. This is less common but happens, especially after a power surge or electrical event.
Error code SC673-10 on a Ricoh multifunction printer indicates a Printer Engine Communication Error. Specifically, this code signifies that the Main Controller Board (MCB) has lost the ability to communicate with the Printer Control Unit (PCU) or the Engine Control Board. In simpler terms, the "brain" of the copier (the computer part) cannot talk to the "muscle" (the printing part), rendering the machine unable to process print jobs.
First, let's decode the nomenclature.
"Operation Panel Communication Error (Initial Communication Failed)."
error on Ricoh devices is a communication error between the Smart Operation Panel Controller
. It specifically triggers when the "Flair communication" (the signal between the panel and the main board) is not established or recognized. Quick Fix: Power Cycle sc673-10 ricoh error
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) A failing Controller Board (also called the Main
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) error on Ricoh devices is a communication error
. 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?
A: No. It is a communication failure, not a hardware burnout. 70% of cases are solved by reseating cables or a firmware reinstall.
