Mike,
I tried your suggestions over the weekend and I think I may have several issues going on. The link below is to a couple pictures I took of the output of the printer (I can scan tonight if the quality is too bad).
Pic1 - single print middle of the sheet
Pics 2 & 3 - consecutive prints middle of the sheet.
Pic 4 - single print leading edge
Pic 5 - purge sheet
It seems that as the print progresses the banding becomes less and less. I know I do have an alignment issue. Auto align fails every time so I have to do the manual adjustment but the banding never goes away. Starting to think maybe I have a bad ink cartridge or something else? I'm puzzled. I run purge sheets every week (matte and glossy) and its always been spot on.

Thanks for your help thus far,
