How to Fix Ricoh Error Code SC673-10: Complete Troubleshooting Guide
This document outlines the diagnosis and resolution for Service Code on Ricoh production printers. This error indicates a hardware communication failure regarding the Fusing Unit's web motor. Achieving an "error-free" status requires inspecting the physical fusing components, checking motor connections, and performing specific Service Program Mode (SP) resets. Ignoring this error can result in damaged fusing rollers due to lack of lubrication.
The code is a specific Service Call (error) code for Ricoh multifunction printers (specifically the Pro C5100/C5110 series). The number "10" likely refers to a sub-code or a specific counter, but the core issue is SC673 .
Leave the machine completely unplugged for at least .
If you have carefully attempted a hard power reset, verified cable seating, and executed a service program reset but the SC673-10 code immediately reappears upon initialization, the physical internal logic board of the Smart Operation Panel has likely failed. At this juncture, you will need to source a replacement screen assembly or contact a certified service provider to replace the controller board components.
If the simple SP fix fails, you are likely dealing with a hardware issue.
Open the controller box casing at the back of the MFP. Carefully slide out and push back in internal options like the wireless LAN card, additional RAM modules, or font SD cards.
If after following all steps (including controller replacement) the SC-673-10 returns within 10 power cycles, log a support ticket with:
