Hey there,

did anyone come past a similar problem?

Talked several times with support and had the tech from japan here no luck,
and to be honest communication with mimaki germany is a major disaster right now.
banding patterns still prevail.

Unidirectional / Bidirektional / ILL / MFD1 no difference.
Ionizer On / OFF no difference.
Highspeed / Normal Speed makes a difference but just different patterns

Problem Kinda solved
Thanks to Signvinyl for the hints to be sent to our technicians

Turns out it was the carriage tunnel where all the tubes are layed in.
After several days of trial and error the fix was to put additional empty ink tubes in the tunnel to make it more sturdy i guess.
Of course the first question coming to our minds "but doesnt the motor have to work more now therefor will break at some point" was unanswered by the technician.
