    [Misc] copy quality issue on KM biz hub C759

    Hello everyone. I have a C759 that makes color lines across the page when running color. Black and white runs clean. I've changed the ITB and the test page image from the utility is beautiful except for these faint color lines. There's a yellow line about 3/4" from the top, a blue line about 3" from top, a magenta about 1' from bottom. I've cleaned the IUs but no change. I've also changed the image transfer belt. Thanks for any assistance.

    Sounds like it's time for new color image units. How many pages are on them?

    The color image units in that machine have a life expectancy of 200K color pages. It is very common for them to not even make that before they crap out.

    The consumables in the C659 and C759 = Junk.

      An image sample would be nice. Something like this:
      Attached Files
      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.

        Hopefully, that will do the trick. I replaced the Cyan IU and the cyan line has disappeared. I should be receiving a yellow and magenta today/tomorrow. Will pop them in and hope.

        Thanks!

              Thank you for following up with what fixed the issue. Too many people get help and then run, without providing what the actual solution was. This helps others in the future, that might have the same of similar issue, with resolving their issue as well.
