Adjust pinch roller pressure

[Racegrafix]

Is there a way to adjust pinch roller pressure? I have the roller on the far end that is not putting any pressure down, causing print head to hit the media.

I found the issue, in case anyone else has this problem. I must have bumped the orange clip, and it unlocked it from the other rollers.
