xerox v180 paper setting

[Alma]

I am running 80lb Silk Text 118gsm, what would I pick as the paper setting? I am getting streaks on the back?
I am printing a booklet and it is streaking on the back pages. Have changed 3 drums and changed the fuser belt.
Also, when I try to have my machine face trim it leaves a vertical line on the front and back cover, if I don't face trim, it doesn't do it.

The streaks on the back mean the 2nd btr needs replacing. Common problem on versant 80/180/280. Have a search round this forum and you'll see plenty of articles. If you have a service contract just ask them to replace it or you can do it yourself as very simple.

Also has been replaced
I think my paper settings need to be tweaked.

is that the only paper it does it on?
