    Bizhub C253 Many Lines without print image

    Has anybody ever seen such a printed image?


    Bizhub C253! All colors have the same problem. 28942812_10215454920115627_2143661016_o.jpg28942812_10215454920115627_2143661016_o.jpg

      I saw something like this on a Toshiba Weisshorn 2H, after a power outage/surge.

      I interpreted it to be laser self-focus problem. What I did is run the color calibration ... perhaps 20 times. Each time I did it it came back a little better. If I had done it ... oh ... 10 more times, it would have been perfect, but by then I was getting pretty irritated at how slowly it was coming back.

      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.

          Doing it when copying & printing? All internal test pages do the same thing? Any codes?

          I agree with BC it has something to do with the printhead. But since this has 4 separate laser units and all couldn't be bad I would look at a board as the problem.

              These are the samples I made: Does it look familiar:

                  Thank you for the answers.

                  There are no codes.

                  Color calibration makes no difference.

                  The same problem by copying and printing.

                  I swapped the mfp board but unfortunately without success.

                  Now, I will change the controller, because the ribbon cable of the laser units goes directly to the controller.
