Digital BW, The Print

Hello, 
I did a group search but did not find anything although I thought this
was discussed before:

I print UT7 on Epson premium semigloss. When they come out I see
regular roller marks, specifically on black surfaces, in the direction
of the paper feeding. They are not "pizza wheels" but broader marks
coming from rubber wheels.

Is there a way to get rid of that - or can someone direct me to a
website/ discussion thread where a way to deal with it is described?
Like this I simply cannot use Semigloss except for certain photos
without uniform sufaces where this shows up more easily.

THanks in advance, 

Bernie
