Question about Ricoh Aficio SP C430dn Laser Printer
Aficio sp c430dn error sc670. In service manual prepose to replace engine board. But i can find it. Is in SM engine board called Controller board? Also am trying to upgrade firmware. When I put in the SD card nothing happened.
You cannot update firmware when there is an error condition. Reseat all the connections on the controller board. If it still fails then replace part number D0655715.
