Paper Feed Adjustment to the max but still some dark bands

So that I understand this, when you adjust the paper feed from Service mode, does that set up the Zero Default Paper Feed Adjustment value that we can then adjust and tailor made on the printer for custom papers? In other words, would it be correct to assume that if I set up the Paper Adjustment Feed on the Service mode for pictorico paper, then I should introduce 0% for Paper Adjusment Feed when creating a custom paper for Pictorico on the printer?

Thanks again Walker,
