    [Error Code] SC220 on Ricoh MP C3000

    I am working on a Ricoh MP C3000. The first error is SC541. I replaced the thermopile. Now a new error appears SC220. I have checked and cleaned the Laser Unit as well as the connectors. Also checked the Power Supply Unit and found one harness for relay not connected. I cannot find the other connector. Do you know where is the PSU relay located? Thanks.
