    MXM363N image quality

    This machine has several issues but currently trying to resolve a copy quality problem, single sided and 2 sided (see attached scan). In any mode other than text I get a faded image (first page), in text mode the copy is good (2nd Page). This happens through the DF or on the platen glass. When I go into simulation 46-2 auto exposure (or any exposure) I get a good copy. Unit has the most recent firmware. Not really sure which way to go since we have tried new drum, developer, developer unit. Have performed OC white reference. Thinking of replacing the PCU next but thought I would see if anyone has a better suggestion.

    Thank you for your time and effort in this matter.

    I would check crop 46-19. Make sure it's set to mode 1 and not mode 2. Found this once and it gave me very light copies on one side and in several modes.

      Bil, I know you have checked if the machine is in toner save, right?

        You could try running 44-2, 44-6, 44-26 then perform auto copy adjustments using 46-24.
        Sim 63-3 might help but you will need a SIT chart which i think are bloody expensive. Ive never tried it before but ive heard of it helping on color machines.

          MXM363 isn't a colour machine though Lawrence.

            Thank you Jace. It does happen to have a CCD however and use the same process to scan the document into memory.

              Indeed you are correct, I just found the colour part a bit funny.

                It can scan in color, therefor, sim 63-3 is valid.

                  Again, true, although I did not discredit the 63-3 either. To have said colour-scanning would have been more technically accurate, but apparently I'm the only one finding the humour in this.

                      Actually I think it's rather amusing (in an irritating sort of way) myself. I'm not sure I understand the reasoning as the U version has a standard non-color CCD and the N versions have a color CCD (which calls for a SIT chart to calibrate). There are a lot of amusing/head scratching features with this model.

                      Thanks to everyone for all of the suggestions, so far have improved the CQ but still not acceptable.
