Epson Epson Artisan 710

black lines when printing

Hello,
I have an Epson Artisan 710 that prints very narrow, vertical black lines, evenly spaced at 1 inch apart, when printing color. Paper type does not affect problem. I have aligned the ports, cleaned the heads, and done every "tool box" problem solving item that is available in the software that came with the printer. These lines are not there when printing text....just color pics.
Any ideas?
Thanks
