I have a few questions I don’t know much about this machine so bare with me, the first image you can see there’s some horizontal banding and looks grainy I replaced one optimizer phead that was old and you can see in image 2 and 3 that didn’t really help so I’m not sure on how to move forward about that the other op phead is in warranty and same with the ink and but for the banding I ran the calibration and included it as picture 4 and not sure which one looks the best to go with I was thinking either +2 or 6,8,10 look good, thank you
