While printing on Epson AC C1100 I get scraches in the print, only in the colored surfaces of Red Yellow and Cyaan (in black this is not the case). To solve this problem I tried anaother C1100, which gives (exact) the same results, the scratches are made on the same place. So I consider it probably will be a softwareproblem and like to know the best way to install the C1100 on Windows7. Who can help me?
