    MX-5141 with Humidity sensor code.

    Hello, this machine is giving us F2-58 humidty sensor error. This machine over the years would occasionally throw this code. Now the code will not reset. The machine still works though. We replaced the sensor itself, changed the PCU board and updated the firmware. In the sims the sensor is reading so it seems to be working. Not sure what else to look at on this one.

    We had to replace the wiring harness to right side door. Not fun. I think we left a lot of the old wiring in there and just worked around it, lol

      We once had a issue with the PCU PWB on a MX-2640N.

      One faulty part was the cassette unit which made that error. ( MX-2651 )

        Did you try cleaning/checking the connector where the right side door/machine meet? I've had bad connectors causing random errors before, and even fuser codes with the fuser connector being a little dirty.

            This is at least part of my plan when I go back.
