    If I make a copy the first page look but the second page will have extra line or color.But if I only print or make copy on BK it is fine . The Bk copy or print look good with multiple pages . Please help!

          What happens when you try a color registration adjustment?

              Your color registration is pretty awful on the later images. I'm suspecting some sort of drive problem with the primary transfer belt, maybe a gear or pulley, maybe the belt has a snag on the edge. For some reason the primary transfer belt is not rotating smoothly. =^..^=

              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.

                  clean the laser then do the reset initialize then gradation. also clean the two idc sensors first(color reg sensors) this fixes 99% of this issue

                      Remove the fusing unit, look on the frame right below, clean that sensor. That is the Fuser speed sensor. When it is worn or dirty, It can cause this issue, but only on multi-page runs.

                          Look for warning code P14 P21 or P31,33
                          Whatever
