    ADF Open Message

    Hi guys.
    I have a C550 and when i want to use ADF it says 'the part indicated by [arrow] is open'. I had this problem before and it was for msposition of ADF on scan. But in this machine i changed everything you name it, from MPF to PRCB and even all scan boards. Nothing changed, it driving me nuts.
    Any suggestion plz?

      Check the actuator on the DF original tray is not broken off or bent out of position

              check the reed switch under the plastic under the magnet from the feeder.
              We know a thing or two because we've seen a thing or two.
              The medication helps though...

                  Yes, the above is correct. I downloaded the sm for this machine and saw the answer there. I don't service minolta, but was curious why no replied as to this switch. If he swapped out adf then in my thoughts had to be the adf connectors as he had replaced the boards also. Now, he replaced everything and it was driving him nuts. If only he had looked at the service manual first, it would have been an easy fix and bet you 99.9 its the reed switch.
                  panasonic small mfp dp-190 has a similar design and if you don't like to look at service manuals you pay.

                  The reed switch is not on the adf, but on the front of the scanner, under the cover i am guessing. there is the magnet on the front underside of the adf, that when closed engages the reed switch to open or close position according to the design.

                      Yes that was exactly the problem and i fixed it yesterday by replacing that switch. I did not know there is such switch under the cover.
                      Thank you very much my friends.
