Nozze and alignment ok, printed with Lightroom, printer connected via lan, TIFF photo 16 bit, custom ICC and custom paper created with canon media config tool. Highest quality. Rare times I have some lines (horizontal, in the direction of movement of the head) in the first part of the print. I have some inks low, but other prints are ok. I do not think a banding problem. What's happened? Thanks.
