    Err. 90 = The data in the flash memory is wrong.
    Go auto zero.
    Long press plate change button. Then menu 02.

    Hi Drukman.

    How do we go to auto zero?

    The flash memory? Hard drive in the console?

    Auto zero on PU : Long press plate change button. Then menu 02
    flash memory: CPL PU flash memory. No HD in the console.
    PU=Printing Unit

    We changed out/ swapped the Weko board (blue box inside the door) from unit 3 to unit 2. The error 90 followed to unit 2.

    Is this because the box has gone bad or is this because we need to adjust the board via CPL tools?

    We are having a technician looking at the Weko box/board to see if it is not working right,
