Great Engineering | Are my drive roller and pinch roller working as they should? @GreatEngineering | Uploaded 2 years ago | Updated 3 days ago
This test can be easily performed with a piece of paper.

Follow our video to check that your blue drive roller is operating correctly in pulling your backing material through.

If it's too easy to pull paper through, you may need a replacement drive roller, or to ensure the grub screws on either side are tightly nipped up and correctly tightened against the flat on the shaft.
