what would cause this type of banding on an sp-300v?

I also think it's ink starvation. Due to environment temperature or some other causes, the ink flow (usually the black) cannot cope with the printhead demand under high speeds. That's why when you changed the profile the problem gone. Sometimes, using the big dampers can help with the problem. I think the latest XJ and XC series have factory fitted big dampers.

99% of all of my branding problems have come from profiles

I have a rule here... Never, ever, under any circumstances use a profile that starts with "generic"! You're just asking for trouble!

That's what I'm seeing. I don't see any "banding" in the pics. I see a few sections of the media that were printed with less ink than other sections. Looks like ink starvation just like the sample pics here.

AFAIK, "banding" is what happens when your head passes either overlap the previous pass too much or don't come close enough to it.

I had the same issue on my SP-300v,

The problem when away after I replaced the Black & Cyan Damper.

yeah when I replaced my head I replaced all 4 dampners. Also Robert M has been great to deal with and has helped me every step of the way.

#1 Damper - replace
#2 Media - try another brand
