    Why don't you just replace the non contact sensors?

    'm not changing the nc sensors on a new station... they should work
    fuser now replaced with a complete used unit...now works
    will then test the existing new unit with the nc-sensors when they are delivered.

    I've seen wiring issues more of a problem than the sensors themselves. Always a really old unit though, never had a bad one out of the box...

    Before you change any PCB's, inspect the ITB for rips, clean the ITB unit, could be arcing. Also check the power outlet, dose it have a surge protector that records power events?

    the problem seems to be solved after 1 week test run with a new replacement heater. the first one was "new defect" ...no idea why

    in 31+ yrs in the industry, I've had ALL brands that the new genuine oem fusers FAILED out of the box.

    they are assembled by HUMANS therefore there is a margin of error built into the product

    "shit happens"

    The proper term is "Out Of Box Failure"
