    [Error Code] 542-1 error code

    In September we installed a new Ricoh MP5002. Recently we have been getting SC542-1 error codes. We clear the error code with 107 but this has come back several times. The fuser unit and roller has been checked out.

    Have you tried replacing the centre thermistor? What does its temperature reading say?
