    MultiXpress C8640ND

    Machine constantly shows "Tray 1 cassette is pulled out. Insert it"
    Can see nothing wrong internally
    Have swapped tray one with tray 2 and it works down there so cassette is not broken
    Detect system is all behind main Power Supply so cannot test any of the sensors as unable to run with power if you want to look at mechanism.
    Swapped the two photo interuptors which I thought were tray in and lift level limit without any change of message

    Just to add insult to injury it is also well out of my normal area so not really convenient to just pop back and try something on the off chance it fixes it or to eliminate it.

    Any help appreciated

    weird one.. have you tried flashing the machine with a firmware update?



    samsungs love firmware, it is their life fuel


    ..otherwise could also check that the feed clutch is working on tray1
    1. Enter service mode (hold 1,2,3 on keypad > enter "1934" as password)
    2. Diagnostics > Engine Diagnostics
    3. Choose 101-0080 T1 Feed Clutch > Start
    4. See what happens....

      Could be a broken flag or a photo sensor came loose.
