Recently I can't print using luster paper without smudges on my prints. These occur at the left and right edges of the prints. I use ImagePrint with Phatte Black ink so there is no changing of cartridges. When I use matte paper there is no problem. I know I have the correct settings. I have written Epson, the Epson group on Yahoo and gotten no responses. I have had the printer a couple of years and this is a sudden problem. I have done all the nozzle cleaning, etc. Any ideas?
