Hi! My name is***** may be have some enlightening information for you.
Code SC542 means that there is an issue with the fuser thermistor. It could be the temperature, it could be a bad roller, or a bad BCU. It is located on the top of the fuser above the hot roller.
Best case scenario, it just get dirty or gets a little loose. If it keeps giving you problems, the part probably needs to be replaced.
To clear the code, press the yellow clear modes key and then press 107 on the number pad. Then press and hold the clear stop button. Then, press the Copy SP Button. Open the front door and then turn the front, left power switch off and back on and shut the door. That error code should clear,
Let me know if any of that helps but I am 99% sure that is the issue you are having.
On THIS model, just press Clear/Stop,1,0,7, Clear/Start.
Each key should be held until you hear a beep. That should clear the error.
Yes. I couldn't see clearly but that's where you need to be.
When you get into maintenance mode, you should be able to press 1, 0, then 7, and then color start again.
Honestly, that should be how you reset the code. But any machine or device that throws an error code has an underlying issue that needs to be addressed. I am actually about to step out for now so I will opt out and let another technician have a go. I hope the issue is resolved soon! Thank you for allowing me to work on this.
