          Bad IU's I would think. Do a single color copy of something for each color and see which is giving you an issue.
          Color is not 4 times harder... it's 65,000 times harder. They call it "TECH MODE" for a reason. I have manual's and firmware for ya, course... you are going to have to earn it.

              Crappy photo.

              Is that A3? And the image repeat is in the main scan direction? In Magenta? I'd wager a magenta laser malfunction... After eliminating the easiest/cheapest possibilities, try to swap the magenta laser with another color.

                  Nope, is an A4, sorry for the crappy photo,
                  taken by my mobilephone.

                      No problem about the photo, we do what we can with what we have. Just be sure to give as much info as possible next time.

                          Go into service mode, test mode, and kick out a gradation print of all 4 colors invidually. This will narrow it down.....

                              I would like to know which is used for this job. From the image (printed text in image) attached, it looks like Transperant PVC media. If so, it could be Fuser unit. Also please make sure correct toner is used.

                              Hope this helps.

                                  Check the two green levers on the fuser aren't pushed all the way down in the envelope position. Have seen this cause double image and dirty copies. Levers should be flicked up for normal printing
