    MX2640 F2-58

    Anyone help with a F2-58 error on a MX2640, machine is clean and serviced, latest firmware and all parts within life and print and copy quality all good. Customer can use it as a copier without any issues but when they print to it, the machine displays a F2-58 code, customer presses OK on the screen, the code disappears and the machine prints fine.

    ive read the manual but find it hard to believe this needs parts changing and maybe a PCB as itís working fine?

    What kind of environment is this in. I have a similar issue with a unit in a very dirty area. My short term fix is to clean the right side door (the one that slides out) connector either with air or alcohol. This will get the code to go away for a few months.

    Good luck

    F2-58 is the humidity sensor RDTCH0228FCPZ in the MF Tray Unit

    You can get this code if the air flow is blocked on the right side of the machine, or as mentioned a dirty environment.
    Go into SIM and look at the reading, if it is dramatically different than the other humidity sensors, it is most likely failing.


    Failing to plan is planning to fail!!!
