I have a Pro 200 that's started leaving ink streaks in the corners as the end of a 19x13 print is finishing. It's as if the paper and the print head are banging into each other because lately I've heard a clicking noise as the last couple inches print. We've tried all sorts of remedies from cleaning the head to new ink tanks to different levels of paper in the bin etc. But, it's getting worse. Has anyone seen anything like this and, better yet, have a solution? Thanks in advance!
