I replaced every pinch roller on my 1204. They break down from use, they are a hard plastic type material. There is a lot of them. But when they go bad it does not leave uniform lines like you have but more of smudge marks. I print everything with the head on high and not low.
Mine does that as well if I'm laying a lot of ink. I put it to a couple things, static and the vinyl not being drawn tight enough with the take-up roller. Like John Best, I print everything with head high, but I still get those marks from time to time. Check your head carriage for errant dust bunnies... the one major place I had was where the cut-off knife would have been (just in front of the "lock" that needs to be released to move the head from the docking station). I cut that part of the carriage off and it made a huge difference in how many drag marks I was getting.
