Our print office printer is in loop. The display continues to indicate a maintenance warning following the clearance of a paper jam in fuser unit. I have rebooted it, switched it on and off, but the message is not removed. I recall that there is a certain simulation mode or a combination of keys that allows a sharp mx3640 clear error code to be done, however, I cannot recall the actual sequence. I believe it is typing the numbers of the keypads in some sequence e.g. press the # key or the C key to access the service menu. Having the step-by-step instructions on how to reset the inner state would be an excellent favor because then we can resume the process of printing our reports.
How do I perform a sharp mx3640 clear error code after a fuser jam?

You need to hit the # button, then Interrupt, then C, then Interrupt again in quick succession. Once the screen changes, type in 14 and hit the Start button. It will ask if you want to clear the trouble, just hit Yes and reboot. Works every time!

Honestly, if it’s a fuser error, you better check if the heat lamp actually works. Resetting the code might get you back to printing for five minutes until it realizes the fuser isn't getting hot and throws the code right back at you

Is it a U2 code or an H code? If it’s a maintenance code (TA or FK), you might actually need to replace the parts. But if it’s just a "Clear Error" situation after a jam, the #, Interrupt, C, Interrupt trick is the way to go. Good luck with the reports!

Be careful messing with the service menu if you don't know what you're doing. You can accidentally wipe the calibration settings if you start poking around in other simulation numbers. Just stick to Code 14 and nothing else!
