any epson printer experts?

I have an epson photo 700 that has been great for five years. Now I am getting awful banding when printing graphics or pictures in color on photo paper. It happens with different brands of photo paper. The settings are correct. I have run utilities/head cleaning numerous times. It works ok with regular paper.
any ideas?
It looks like I may need a new printer, which I really don't want to do.

 

Try physically cleaning the cartridges - using a slightly damp lint free cloth gently clean the nozzles and the copper contacts on the cartridges themselves.

 

this guy tore it right down and manually cleaned it, lots of pics

and a page on banding even when the test apttern appears OK

try cleaning like the guy on the site that vwtick recommended. that guy put some effort into the printer and made a difference.
