Help with roller marks please

[karma23 0]

Hi, i just got a MH721 and having a great time learnignto use it.  Only problem is i have roller tracks showing up on my vinyl.  Was curious if anyone can help me by telling me if going clockwise or counterclockwise on the roller adjustments to loosen up the tension.  Any help would be appreciated. Thanks in advance.

Roller marks are normal and they normally come out after then vinyl is applied.
