  A differential circuit output error was detected between the detection output and the compensation output of the Fuser Unit NC Sensor.

Your fuser is not coming up to temperature. Power off the printer. Remove the fuser and check for any bent pins or breaks on the hot roller. If all looks all right, reinstall fuser and power up the printer. If the error returns. Your fuser most likely need replaced. I hope it's just that. Replacing the Main Control Unit Printed Wiring Board (MCU PWB) or the Main Low Voltage Power Supply (LVPS) are not cheap! Then again, neither is the fuser! But not as much as the other two!

Try supping the black drum with the yellow, If you get a diffrent fault code replace the black drum.

Coould be just in standby or network is not working

your error is : C210 Paper conveying motor

check paper motor remove and check clean with alcohol and than oil it

OPEN HEAT ERROR (When warming up, it has been lower than 68 °C over 25 sec)
Meaning : Thermister is not connected to main board or contact point is loose at power on.
Solution : Check thermister contact point, Heating Lamp & Thermostat.

Open and close the paper drawers!!! Super stupid solution, but trust me... it works!

Hello,this fault code indicates a problem with the process control system.The printhead temperature dropped below the head cleaning needed threshold and that's why stops warming up.The first you need to do is to verify the temperature of the room that the printer is,if its too cold,near from an open window...If was too cold and not in the room temperature then move the printer and your are done.If this doesn't solve your problem run the Monitor Heaters tests with all heaters ON.Are the heaters operating correctly?If yes replace the Electronics Module.If no you have to inspect the harness to the failed heater.Is the harness damaged?If yes you must replace the harness.If no replace the problem component.
Good luck:)

You have either an intermittent Electronics module or a intermittent print head. Lowest cost new from Xerox is $750.
Phaser printers are expensive.

That has to do with the process drive gear box. May be mis timed or a gear broken.
