Spectra Galaxy PH 256/30 AAA ink jet head issue


Hello guys,

I am writing this here becouse I am stuck in tryings and got no good results with this head.
Head is new and is Galaxy PH 256/30 AAA.
Is installed on KirkRudy wave jet. It works on UV becouse I most print on plastic.
Issue is that white lines from picture 2.
I understand that is must work on 95v no more ( didnt got explications why )
Actual settings on this machine are:
50 celsius degree work ink temp, 95v, 3.3 meniscus and 21 lung ( lung value is maximum on this machine ).

If there is some one who got same issues and can share, please answer here.

Thank you Kind regards
