My employer has four mimaki 7151 Plus II's, and some jobs that have black are banding on one. Nozzle check & test prints came out fine. So i tried a feed comp and got the below. Why the heck are there so many lines in the feed comp test? All four of the other printers that are the same model do the same for feed comp test. The original setting was 180, I changed it to 100 assuming it looked better. Still have banding though.
