SC 542 Basically the machine is telling you that the fuser did not reach its target temperature in a specified amount of time. In normal circumstances this code will appear if the thermistor is not maintained or replace periodically or in abnormal circumstance the heat lamp blew. This is a Service Tech reset code. Once the error is detected, the printer is toast until you manually clear the error from the keypad. Even though the printer is physically fine, it won't come ready until the prior error condition is cleared. basically you will have to care a service tech to clear it
