I am able to print on 8.5x11 plain and perforated cardstock, 12x18 heavyweight paper and legal paper printed fine.
I am having trouble with 12x18 synthetic paper (performance polyester) 8 mil and 260gsm. It discolors on the last 3/4" inch of the trail edge. I would have uploaded an image but I keep getting an upload error. It is a picture of plants and goes from bright green leaves to a bluish green. I have tried a sky shot of yellow and it looks fine.
I have tried different paper settings. I tried to cross reference with the Xerox C60 paper specs guide to the best of my ability, but no success.
Copier has 6400 color prints and 400 black prints.
Any help would be appreciated and I will continue to try and get a image up as well.
