stains in middle of print

Hello Walker/Dana,

 

I have some strange stains/spots in the middle of my prints. See pictures attached.

yesterday a few stains in one print, today again after cleaning wiperblade and head. Nozzlecheck was ok.

Cappingstation and wiper blade are fairly new and i also replaced the dampers a few weeks ago…

i Did a manual head alignment , all parts of it on the same paper.

Could it be the new dampers are tight to much? What could be the cause?

 

printing on a 44" roll , epson stylus pro 9880, Hahnemuhle Fine Art baryta Satin , K7 Selenium inks , linearized curve

 

Kind Regards,
