    3 times each option; total 9 times.

    It's also recommended that you place at least 10 white sheets over the chart you're placing on the glass.

    Also make sure the paper is white and not yellowish.

      you should run each one 3 times...so yes 9...however...it depends on your readings....in the 2nd column ( i think it says "conv value") all readings should be between +/- 100...in the last column "adj Value" it should be between +/- 60....if it isn't within....then you have to keep doing it until it does...or you have another problem. obviously if it falls within the range 1st time, there's no need to carry out the other ones....

          so guys,

          Tried gradation adjust aswell still nothing, all the readings are within range tried image stabilization afterwards still nothing.

          Here the problem once again.

          When its full black, the print come out nicely.
          When i send print from computer, it prints perfectly the quality is good
          but the problem starts when i COPY something.

          I copy a black original in full black and the result is fine
          I copy a black original in auto color and the result isnt in black but instead its all BLUE.
          I copy A COLOR ORIGINAL in black it prints it in all black fine
          I copy a color original in auto color and it messes it up the color badly.

          i am also attachibg the scanned files.

          original:


          copy



          orignal2:


          copy2:



          i am out of clues, any help would be really appreciated guys

          and thanks to the guys who are already trying to help !

            Perhaps you could try these originals? It might tell you more:

            I'm thinking that you're missing magenta and yellow, but only in certain areas of the copy.
            =^..^=
            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.

              I have already tried similar ones, black dont show at ALL and all other colors are pretty messed up as well.
              The thing is all the values in gradation adjust are perfectly within range and you are also right about
              missing magenta and yellow, thats is the problem in full color the copy is very messy, black is not showing AT ALL and all the other colors are rough as well.

              First i thought maybe magenta and yellow are having trouble and thats why the colors are so messed up later on i noticed that the black isnt there at all.

              just a question, am i supposed to take our IUs before data clear? because i didnt do it with this machine, i have done data clear before and never actually took out IUs.

              is it possible that i have to replace IUs? if yes thn why do i get perfect copy when i send print through computer?

                Though I don't have a clear course of action for you, I can say with some confidence that if the prints look good you will not get any improvement by changing consumables, i.e. imaging units.

                When you do the gradation, do the print outs appear with all the colors properly represented? I'm guessing yes.

                Do you have scanning set up on this machine? I would set up a simple SMB folder on my laptop, then scan some color documents to it. I think you'll see the same color anomalies in the scans. I think it's unlikely to be a mirror or cable problem. It could be the CCD, or the board that does the image processing. Whatever the problem, it's likely to be expensive to fix. =^..^=

                  Re: Bizhub C 352 Data clear

                  yes when i do gradation adjust the print is very good throughout.
                  could be CCD but the thing i dont get, how DATA CLEAR can effect CCD? or any other board for that matter?

                  Doesnt matter how expensive it is, we got all the spare parts, boards we need, just need to figure out thr problem first.

                    I think I would think seriously before doing a data clear on any machine in the future. It rarely resolves problems. More often it creates problems. =^..^=

                      Re: Bizhub C 352 Data clear

                      OK SOLVED THE PROBLEM

                      it was faulty board near the assy its responsible for creating images, changed it and worked fine, i think capacitor on the board is faulty, going to change it and try that board on other machines

                      thanks alot for the tips and all the help guys really appreciate it you are all great ! love this forum
