Having trouble recently with the tension bar on laminator not sitting flat while laminating. The left and right end alternate in rising then falling which is leaving a slight wave/ripple effect in the end product. I assumed this would disappear after mounting the print with the manual laminator but it's still there and is weeks later. I don't have any photos at the moment but I'm sure it's just a matter of getting the tension bar to stay in the same position. Any help appreciated.
