Vertical Lines on prints S40

Is there any print on that vinyl? I'd be inclined to say bad media first up.

 

Brand new roll doesn't mean anything.... Can still be bad one.

 

My guess is that the media is rubbing up against something.

Check the vacuum settings and increase enough to pull it down to the platten, and run a small test print.

Hope this helps.

 

Assuming that you tried another media and another file with same results; ruling out media or file / software issues... How about the pinch rollers are they clean ?
