: Unless you're confident in your technical abilities and have experience with printer repair, it's usually best to avoid attempting DIY fixes for SC errors, as they can lead to more damage.
Download the latest firmware specific to your precise Ricoh model from the official Ricoh support portal.
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.

The Ricoh SC673-10 error is intimidating when it first appears, but it is far from a death sentence for your machine. In the majority of cases, the fix is as simple as navigating to and flipping a value from "0" to "1." If that fails, a physical inspection of the USB harness, a firmware update, or (in rare cases) a controller board NV-RAM replacement will get your machine back online.
If the error occurs during the boot-up sequence, try removing and re-installing any optional RAM modules.
In rare cases, corrupted data on a component called the NV-RAM (Non-Volatile Random Access Memory) on the controller board can cause this error. In this situation, replacing the NV-RAM, or the entire controller board, may be necessary.
