Question UCJV330 - Black streaks when printing Clear.

[Kemik]

Anyone else have this issue when printing clear gloss?
I get random black steaks across the width of the page when printing Clear UV Gloss, 600x1200 Uni-Direction, single pass, no roll back, 44/44% UV, head height 2.
It can happen with several prints in a row or just popup after 5 good prints, there is no consistency as to when it happens.

Anyone have or solve this issue?

Check wiper, clean underside of print carriage but avoid scrubbing down the nozzle.

This still happens after a manual clean.
The 1st print may have a black streak, and then next print won't, even without a clean in between.

If media is lifting, might want to turn vacuum strength to high if not there already. Also, make sure rollers are aligned.
