Hi, First I advise against using generic inks as they do fade over time 6-12months. Next If you have a colour cast leave your settings in Easy Print as Glossy if that's what you are using. Next go to File-manual print & select "Plain paper-Fine-papersize-untick-high speed. Then click OK it will then start printing. By unticking High speed you should get rid of any lines. Let me know how you go. erniegoulding76@gmail.com
