    [CQ] wavy lines

    I have es2505ac that has void areas on one side of the paper, running landscape direction.
    It happens intermittently on copies and prints. See samples.
    It has recently had new drums and coronas.

    Since it seems to affect all colors equally, I would suspect a 2nd transfer issue. Perhaps the 2nd transfer roller isn't making a good electrical connection, or the door isn't closing completely at front or rear.

    Also the primary transfer belt may be dog-tracking. Do an emergency stop to see if the latent image on the primary transfer roller has the same defects. You should see wrinkling of the primary transfer belt if this is the case. =^..^=
    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.

      Ended up being primary belt unit, even though full image was on the belt.
      2nd xfr roller tried but didn't work

          Interesting results, could this be caused by the 2nd Transfer Facing Roller - the one under the belt making contact with 2nd Transfer Roller? I've seen a bad one causing a faint image across all page at random pages in continuous print.
          Defects are simple, our mind is complicated

            Also make sure that the electrical contact to the facing roller is ≤0.10Ω. You'll get voids crossfeed in images exceeding 50% fill at 57mm intervals. Heaviest fill leaves voids of 10mm wide. 11% fill leaves voids barely discernable. That was not an easy one to diagnose ... and I did it to myself, of course. =^..^=
