Roland VS640 Black ink stripes on yellow

First: Sorry for my English ;)

Every time I print areas with yellow (orange etc.) ink, the first
2cm are printed fine. I think it's the last pass of printing when
black lines appear.

Cleaning is performed countless times, normal, medium, powerful,
manual and manual by flooding the capping station for ~15 Minutes
with cleaning liquid, the head above. The chock cleaning is performed.
The capping station is new, all wipers are new.

If you can see on the pictures attached, there is a pattern appearing
partially in the black stripes.

My first thought was a damper-Problem, that there is maybe a
vacuum and the yellow nozzles will soak up black ink, but in this
case all or more nozzles must be involved.

Firmware is the latest.

Anyone an Idea?


Thanks,

Maik
