Hello Norman1987,

That looks like banding, when you do a nozzle test, are you missing any nozzles. If you are it could be that is causing the issue and you may need to reach out to the local tech to replace the head as a worst case. Also if that happens on this file alone it could be something in the file that the software is picking up.If you have any other questions please reach out to Roland or your local Dealer.

Thank you,
