Mimaki JFX200EX Nozzle Drop

Hey Fellas,
Im having this issue when printing, it starts fine and suddenly after 70cm it starts to band. it happens with both 6 & 8 pass bidirectional. It happens as well with more colors not only magenta. I have brand new (1 month heads), test print is perfect and both pressures as well. The head gap is 1.5mm.

Any idea i would gladly appreciate it

Thanks

Usually in these situations I do an air purge first. Tends to fix ink flow issues.
