tension is everything! our tension on our feeder roll, the one that holds the lam, is almost all the way tight.
VERY IMPORTANT! make sure the tension on your take up roll, the one that takes up the backer of the lam, is NOT too tight. you want it so it BARELY keeps up with the lam going into the pressure rollers. too little and the backer will get laminated with the print, too much, and it will put uneven tension on the lam going into the pressure rollers and will cause wrinkles.
when you change out backer rolls, you will need to adjust the backer tension as the roll gets heavier and heavier.
we litteraly are feeding, adjusting, and monitoring through every print we lam. its comical to watch, but it works, and works well.
make sure your speed is set slow to no more than medium. the faster the speed, the more problems that will arise.
also we DO NOT use kraft
paper. we have one person feeding and one person catching.
your laminator can and may be not aligned perfectly. ours isnt. but it works fine even without it being adjusted correctly because we know how to feed it and adjust it on the fly.
its like anything else. its a learning curve. a knowledge of what is EXACTLY taking place with all facets of machine will yield an understanding of how it works and what does what.
this is crucial to diagnosing what is going wrong and how to fix it.
your machine is FINE. laminators are by far the hardest machine to operate as its 100% mechanical. there is no hit print and the software, rip,
computer will do the rest.
