Keep it flat against the feed tray.Ģ.2) If you see serious wrinkling on both sides of both film and paper, the laminating rollers probably need to be closed and locked. As soon as the rollers take the item, grasp the back corners and pull back and down on the item so the folds or wrinkles are pulled out and it is held flat against the feed tray going in. Make sure the leading edge goes into the laminator flat and parallel to the rollers. If an item has been rolled, folded or wrinkled beforehand, first flatten and smooth out the leading edge. If the item is not laying flat and smooth when it goes into the laminator, it cannot be expected to come out flat and smooth. An Educator does not have a top idler.)Ģ.1) Make sure you feed the item so that the leading edge is parallel to the laminating rollers. Look at the threading diagram for your machine.
Make sure both sets of rollers are closed.ġ.4) If the top looks fine, but the bottom shows lots of bubbles and wrinkles, the bottom idler is probably not threaded. If the laminating and pull rollers on your machine can be opened and closed, The film should clarify just as soon as it hits the heated areas (the two black parts we call the shoes). An Educator does not have a top idler.)ġ.3) Make sure the machine is up to temperature. Take a look at the film threading diagram in your operators manual. Make sure the film is threaded around both the top and the bottom idlers. You are only concerned about wrinkling you can see in the finished work.ġ.2) Make sure the film path is correct for both top and bottom webs. Remember, you are not concerned about wrinkling of the film on the shoe. It's unusual to need more than 5-6 turns of tension even on bigger laminators. A larger laminator with 5-mil or heavier film may require 4-5 turns of tension on each knob. (Four half turns equals two turns, for example.) DO NOT use too much supply roll tension. From the point where each knob just begins to press on the spring, add the correct tension by half turns.
Loosen both supply roll knobs until tension on the spring is released. Thinner film needs less tension, thicker film needs more. Is there some resistance? On a 25" machine with 3-mil film, two turns of tension on each knob should be about right. Turn the rolls of film (supply rolls) in the unwind direction. Any laminator needs a certain amount of resistance to the unwinding of the supply rolls so that the film lays flat as it goes into the nip of the laminating rollers. 1.1) The film will wrinkle if there is not enough supply roll tension.
