    7052ci scanner scanning wrong colors

    We have this 7052ci that scans colors wrong, meaning they are trying to copy blue and it comes out green. Prints are fine and we scanned it to a flash drive and the document is green also. Never had any issues like this with a machine so I am not really sure where to start with it. Anyone had an issue like this that can point me in the right direction? Thanks.

    Could you upload some samples please? Also, wouldn't be a bad idea to try and scan those same docs on another machine. Had an issue once on an old Sharp that was trying to scan the color green from a print out off an HP, and it could NOT read the green, it just kept making it black no matter what you did. But, then an even older Sharp they also had there scanned it just fine. There wasn't a setting we could change to make it scan that color from that HP printer.

    Also, is it all docs that it's scanning wrong, or just one or two?

      We tried it on another machine and it was completely fine, they have 2 of those and the other machine works fine and we tried it at the office and it worked fine. I will attach what we are getting so you can see it.

        Here is a sample, everything that is green should be blue and you can see the other colors are off as well.

          If you have the appropriate sit chart, I would also try running through that adjustment, maybe even do firmware first if you haven't yet. You can also backup the machine, and then wipe it in U021, and see if that makes a difference(doubt it will do anything, but you no never know).

          Not that it matters a whole lot, but what ADF is on the machine? And is it the same one as what's on the other one they have, and one you have at the office? If it's the same, I would try swapping the ADF with the other one and see if the problem moves - that would narrow down quite a bit. I also have not worked on the 70ppm+ Kyocera's, just the 6052 and 6053 series'.

            We did firmware and attempted to adjust the scanner but it didn't change anything. 70ppm+ machines all come with the same feeder, you can't put a different one on them. This also happens whether you use the feeder or laying it on the glass. We have not tried wiping out 21 though so that is something to try and see what happens anyway.

              Simplex + duplex?
              Did you checked scanner movement for dp simplex scan position?
              Are you able to run U411 with chart a and did you run it?

                Looks to me that you’ve lost red in the RGB mix. You could try the scanner calibration test chart and run U411, but I think you might have a hardware issue. Do you have a lens assembly you can swap it with?

                  This might help:

                  https://www.copytechnet.com/forum/te...me-cool-copies
                  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.

                    We didn't check that because it does it on the glass also so we just assumed it was scanner related. I will ask the tech if he did 411, I wasn't there.

                      I am thinking hardware related also and we do not have any parts for this machine to swap it with unfortunately.

I can't find an ISC board in the parts manual but you said you think the CCD is wired to engine board so my issue might be that. The only thing remotely close in the parts manual is the
                          PARTS IMAGE SCANNER ASSY SP - P/N
                          302NH93230
                          Which has the actual lens assembly on it but I don't think that is it. We have an engine board but not the CCD calibration chart. I am going to order it today. Do you think it is worth a try to swap the engine board without the calibration sheet?

                            You should get a temporary improvement, but for the best possible quality, you'll want to use the chart. When I installed the new board on my machine the colors were a lot closer to true, but I had a strange 'texture' to the images, which was corrected by the chart.

                            Good luck.

                              Thanks. I guess I will just wait on the chart and try that first. They have 2 of the same machine so they aren't completely without a machine at the moment.
