    [CQ] COLOUR QUALITY PROBLEM IN TASKALFA 3050Ci

    hi,
    we are facing a color quality problem.the machine is new and its crossed only 40k prints. suddenly one day its cyan color output was too bad and color registration also changed , after the registration adjustment , developer refresh and drum refresh it was ok for 10-15 prints then again started the same problem.we replaced the cyan dev unit.
    then very next day there was a laser error code for cyan... we replaced the laser also... from then non of the color is not printing correctly..even we replaced the entire laser unit.... no result....still cyan registration problem also coming frequently... any updates or solution guys....thanks in advance...........

    Check the transfer belt for binding or the rubber strips that are on the edge of the belt

      What about a new cyan drum? When this drum is not rotating properly you also get registration problems.

          And I'm assuming that you've done the appropriate color calibrations for these units?

          It sort of reminds me of the effect when the transfer-to-HVT contacts get bent or out of position, but on Saturn machines. You can investigate by removing the transfer belt, but to fix you'll have to remove the HVT. Fun, fun. =^..^=
          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.

            Looks like laser units to me

              Hello Blackandwhite,

              maybe the solution will be the flatcables from the laserunit.
              We have a lot of problems with the flatcables at the alphard range.
              You got laser error, exchanged the laser but still poor colors.
              Connecting problem ?? Maybe you damaged the connector area from the cable ?
              Can we get the maintenance reports and the service status page, to see which values are in #69 from the service status page and U465, 468 and 469 from maintenance report.

              regards

                    Upgrade firmware to latest version then run u464 AC calibration. Exit maintenance mode go into system menu and run developer refresh 2 times, then set calibration interval to 'short'.

                          just few answers i have for your valuable questions....
                          the drums are mixed ,we thought all the drum units are same..(in the past we did the same for TA300ci and KMc3232e ).we want to check the quality problem..so we interchange the drum units with in the machine itself...
                          we changed the new drums and dev.units...which belongings to other machine...after changing also we got the same problem...so we removed them and replaced the original drum/dev.units...
                          laser units for CMK colors changed....because we got individual laser units ,not the full laser kit like TA300ci...i am not sure about the adjustment execution after the drum mixing.......i hope it was done by our tech....
                          can i get more information about system stamp in U952 and other wrong settings ,what we did in the past ....frankly.... i am not aware of this....
                          can i get the part no for the laser flat cable....we didn't get it from parts manual ....i will start from flat cable....is there any way to repair the defective dev.units ....
                          CAN I TRY TONER LEAK IDEA.... Upgrade firmware to latest version then run u464 AC calibration. Exit maintenance mode go into system menu and run developer refresh 2 times, then set calibration interval to 'short'......
                          please advice .......thanks a lot for your valuable solutions.......
