If you are staring at a flashing red light on your Ricoh MFP with the cryptic code displayed on the screen, your first instinct might be panic. You cannot print, scan, or even access the machine’s settings via the operation panel.
indicates a communication error between the controller board and the operation panel (touch screen). The -10 sub-code usually points to a data line / serial communication failure after the panel’s CPU has initialized but cannot sync with the main controller.
Ricoh machines use SD cards for firmware and application storage. If the SD card in the controller slot is corrupt or incompatible, it can prevent the entire controller from initializing, triggering the SC673-10.
Ensure any external network cables (LAN) are securely plugged in. sc673-10 ricoh error
Paradoxically, updating the firmware can sometimes cause this error. If a firmware update was interrupted or if the update file was corrupted, the printer may fail to boot into the new OS, throwing the SC673-10 code.
Physical vibrations from high-volume printing can slowly unseat internal connections. Power down the machine and unplug the power cable.
To fix the problem, we first need to understand what the machine is trying to tell us. Ricoh error codes follow a specific hierarchy, and breaking down "SC673-10" gives us our first clue on where to look. If you are staring at a flashing red
is a communication error that typically points to a disconnect or failure between the machine’s internal control boards.
Don’t replace the printer just yet.
If the error occurs intermittently or directly following an interruption, the firmware image may be corrupted. The -10 sub-code usually points to a data
Does the error happen or randomly while printing?
Select the sub-engine or specific controller clearance option recommended by your service manual.
If the steps above do not clear the code, it often indicates a failure of the or the Smart Operation Panel itself. Because these parts are sensitive and expensive, it is recommended to contact an authorized Ricoh Support provider for a hardware diagnostic. AI responses may include mistakes. Learn more
The main controller board experiences a temporary software hang or firm lockup during initial boot logic.
