I having tiny white bands showing up in all of my blues. But it only shows up in the blues. I printed a bunch of color swatches side by side. & the only color that showed this was the blues. Has any one out there come across this? I would think if it was a head issue. That it would be showing up across the board. & not just in the blues. Also from doing a head test before the print. It showed all cyan & light cyan heads are firing. This one has me stumped. As one of our biggest customer's logos is a 307c color. Any help or input would be greatly appreciated. Also the printer isn't even 2yrs. old yet.
