Hello! I got my pro 100 about a month ago, and the first two photos, printed on 8.5x11 pro luster paper, were great. Unfortunately, I printed another page about a week later, and there were four thin nearly invisible white lines running through it. I printed another sheet, making sure that the quality was put on the 1, and there were two white lines. I also checked the print head and cleaned it before printing, but it did not stop the whit lines. What should I do?
