Wait for 5–10 minutes to allow all residual power in the capacitors to drain. Plug the printer back in and turn it ON. Step 3: Check Internal Connections (Technician Recommended)
The SC673-10 error code triggers when the controller board attempts to communicate with the operation panel during startup, but receives no response within the designated time frame. The primary culprits behind this disruption include:
: A fault in the controller board, the operation panel itself, or the machine's memory (DIMM).
The necessary Service Program (SP) bit for smart panel communication (such as SP5-748-201 ) is disabled or not properly activated.
The "CATS module" (communication service) may fail to start if specific Service Mode settings are disabled. sc67310 ricoh error extra quality
: The dedicated software parameter governing Smart Panel interactions is turned off within the system settings.
: The USB or internal interface wiring connecting the Android-based Smart Operation Panel to the controller is faulty or unseated.
Follow these diagnostic procedures sequentially to clear the error state and restore structural data flow. Step 1: Execute a Hard Power Reset
Disconnect all network Ethernet or USB printer cables to isolate the machine. Wait exactly to clear the capacitors. Wait for 5–10 minutes to allow all residual
The panel LEDs illuminate but the screen remains entirely blank or unresponsive to touch.
The operation panel is unable to establish or maintain a connection with the main controller.
If the error remains locked on the display, you must manually reset the machine's internal non-volatile RAM (NVRAM) or System Service Program counters.
Turn off the printer and remove the power cord from the wall. The primary culprits behind this disruption include: :
: Ensure no USB devices or SD cards are plugged into the controller or panel that might be interfering with the boot process.
Outdated or corrupted firmware can cause errors when the printer handles advanced print protocols.
In essence, the SC673-10 error is a failure in what Ricoh calls "Flair Communication". The "Smart Operation Panel" (SOP)—the large, tablet-like touchscreen on newer Ricoh models—communicates with the printer's main controller via this protocol. When the printer starts up, if the main controller doesn't receive the proper response from the SOP, it triggers this error. The most common culprits are an incorrect software setting or a mismatch between the installed hardware and firmware.
