Sc673-10 Ricoh Error Jun 2026

If the hardware connection is solid, the software handshake might be failing.

Note: Turn off and unplug the machine before attempting this. Remove the plastic covers near the arm holding the screen.

Tip: After updating firmware, perform a "Memory Clear" (SP5-801) if data backup permits, but note that this erases address books and settings.

Hardware disconnections are common, especially after the device has been serviced or moved. sc673-10 ricoh error

Sometimes a simple "glitch" in the power-up sequence triggers the error.

When you encounter an SC673-10 error, follow this systematic approach. Always start with the simplest, least invasive solutions before moving to complex hardware repairs.

The SC673-10 error is a communication issue between the printer’s main body and its (the large, tablet-style touchscreen found on many modern Ricoh models). Officially, Ricoh service manuals refer to this error as the "Operation Panel Flair Communication Error (Smart Operation Panel)" . If the hardware connection is solid, the software

: Outdated firmware can cause intermittent communication "late" errors. Updating both the System/Copy firmware and the Smart Operation Panel firmware can stabilize the connection.

The SC673-10 sub-code specifically means that the printer controller failed to establish a connection with the operation panel board within a designated timeframe after power-up. This break in the communication loop prevents the user interface from receiving or sending signals to the main engine. Primary Causes of Ricoh SC673-10

Using a multimeter, check the voltage at the power supply output pins going to the controller board. Look for: Tip: After updating firmware, perform a "Memory Clear"

: Potential issues with the USB communication path or the internal flash memory.

After analyzing Ricoh's official service manuals and technical bulletins, the root causes of the SC673-10 error can be broken down into three main categories:

If the main controller board suffers from static shock, blown capacitors, or localized overheating, the serial communication ports dedicated to the operation panel may fail entirely. 5. Unstable Power Supply

Status LEDs on the rear board do not flash normally; other functions like network printing fail. Replace or repair the main controller board. Proactive Maintenance Tips
