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

SC542 is a warm up error from the fuser.
SC 870 is an address book error.
Turn the power off on the copier. Wait 30 seconds and then turn the power back on. See if it goes away.
Let me know if it doesn't.

Enter SP mode, and then turn the main power switch off and on, only.
Please check if the thermistors are the proper ones and are installed correctly in their position properly.
This is also useful for SC542.
Please check the thermostats and fusing lamps for open circuit.
Good luck and please rate me, thanks.

This is a generic answer, as you didn't state the model machine you had. In general, this is a fusing error code; hot roller is not warming up, or not warming up fast enough...
SC542 - Fusing temperature warm-up error
The fusing temperature does not reach the standby temperature within 20 seconds after the main switch is turned on.
Causes:
• Fusing thermistor defective or out of position
• Fusing lamp disconnected
• Fusing thermostat open
You will need to enter into the service mode in order to clear this service code...
