Since I just got it, I've only printed one picture, but I get the lines on the picture, the alignment test page, and the clean cartridges page. The lines were real bad at first, but I ran the "clean cartridges" test and they got much better. Now when I print test pages, the lines are still there and the ink is not very dark. The black is gray and the blue is very light. The lines aren't blurring, just thin white lines the whole way across the page. I'm thinking it has to be the cartridges. I think my best be is to go to wal-mart and buy some new ones and see how it goes, unless there is something else to try?
