⚠️ Warning: Turn off the printer and unplug the power cord before disconnecting any internal cables. Wait at least 30 seconds for capacitors to discharge.
If you are a technician, office manager, or IT administrator responsible for maintaining Ricoh multifunction printers (MFPs), you know that error codes are an inevitable part of the job. Among the more perplexing and frustrating diagnostic codes you may encounter is the SC673-10 Ricoh error.
This error typically appears on newer generation Ricoh devices (such as the Ricoh IM series, MP 6503/7503/9003 series, and some color production units). When this code appears, the machine usually becomes non-responsive, displaying the error message on the Operation Panel (OP) and refusing to copy, print, or scan.
In this detailed guide, we will break down exactly what SC673-10 means, its root causes, step-by-step troubleshooting procedures, and long-term prevention strategies.
The SC673-10 error on Ricoh copiers/printers indicates a scanner communication or CCD (charge-coupled device) read issue — the scanner unit is failing to communicate properly with the main controller or the scanner sensor is producing invalid data.
