Question about Ricoh Aficio AP3800C Laser Printer
Sc672 is a communication error between the controller board and some other component. Did you switch the machine off using the orange power switch on the lower left side, or just the power button on the operation panel?
With the power completely off and the machine unplugged, pull the controller board out by removing the two screws holding it in on the rear left side of the machine. (It should slide right out the side.) Check all of the connections on the board and make sure everything is sitting securely, then reinstall the controller board.
Worst case scenario, you might have a bad memory stick, bad controller board, or another bad circuit board, but more than likely there is a connector somewhere that just needs to be set securely. You can also remove the operation panel (two screws on the top of the panel and possibly two screws underneath it as well) and check the harness that connects the op panel board to the machine.
