Hello, I run a vj mutoh 1624 and I have tried to print a 60"x48" phito on canvas. There is areas of heavy black but otherwise a fairly straightforward print. I have my vacuum setup as medium and I run 31/33/50 with my heaters as this setting stops the head strikes. Running it at 1440x720 and tried with 1440x1440 and 720x720. This is the 3rd attempt at running this print with same banding issues, 2 times same area 1 time 3" from the end. I ran another picture just before this one. 1st picture perfect but within the first 2 feet this messed up again. Any suggestions would b greatly apprecisted
