    [Error Code] C300i , code C 9401

    Hello. When turned on, the lamp lights up, the scanner starts moving and the copier shows the code C 9401. We replaced Led exposure unit, CCD unit, SCDB, CPUB, Baseb,power supply, flat cable, storage and performed a firmware update. It did not help. We would be grateful for any advice! Thank.

    Holy c.ap! You replaced more than all required and it still won't work. Any options added, try without them.
    A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.
    Blessed are they who can laugh at themselves, for they shall never cease to be amused.

      Anyof the trouble codes C6102/6751/9401. Itis caused by the loose screw at the timing belt pulley.Ifthe screw was loosened, the pulley is idling which makes scanfunction faultily.Asthe result, the trouble codes related to the scan malfunction occurfrequently.

      Tightenthe screw if it is loosened.
      Ifthe screw is not loosened, it must be caused by other causes. Pleasecheck the tension of the belt or check other solutions on the servicemanual.

            Have you check the small timing belt on the motor for damage?
            Whatever

              Yes, he's correct. I have a problem with this error on C450i. I replaced LED Exposure unit, scdb, ccd unit, cpub and baseb. FW G00-P8 and GC2-Q9. I replaced wiring between scdb and led exposure unit and ccd unit and baseb. Problem not solved.

                  I would unset and disconnect DF and try machine again.

                      It's usually the timing belt or sun exposure.

                            What does a scan look like?

                            If you'd like a serious answer to your request:
                            1) demonstrate that you've read the manual
                            2) demonstrate that you made some attempt to fix it.
                            3) if you're going to ask about jams include the jam code.
                            4) if you're going to ask about an error code include the error code.
                            5) You are the person onsite. Only you can make observations.

                              When you print counter list it's ok but when you scan it gets bad.
