Need Help Mutoh printing color issues

[Ondrocs]

I recently replaced the print head on my Mutoh 1204. Having trouble when I print lighter blue colors. It has a bad banding or uneven color to it. A nozel check looks perfect, no missing lines or anything. All the other colors look great, even the darker blues.

This is not banding. It's just the media isn't flat on the platen, so the media doesn't receive ink equally.
