Or has the laminator ran enough 30" material that the rollers are permanently smaller where the 30" has ran and thats the center area now with 54" and there isnt enough pressure in that area?
I can attest to this happening to our laminator, i think we have the same as you. The rolls are slightly indented at 54" where the material is normally fed. We were having issues with it but then realized we just needed to reload the laminate an inch or so to one side so it grips again.
