    Fine Black streaks on images whilst using a Roland SP540i

    That was my first thought. The printhead was replaced and the error remains. Therefore something else is affecting the print quality. All suggestions gratefully appreciated.

    Fine Black streaks on images whilst using a Roland SP540i

    Attached are images which show the problem i am having. I have replaced the black print head and the problem remains. I have been advised that the carriage board and/or the main board may be the cause. I am not so sure. Any advice would be appreciated. Jon.
