Label sheets consisting of a plastic facestock, such as our weatherproof and clear materials, are more prone to static buildup than standard paper-based materials. If you find that using the plain or unspecified paper type setting does not resolve the issue, try manually feeding the label sheets through your printer. Another option to alleviate the issue would be to lay the stack of sheets down on a hard, flat surface and then fan through the sheets at all four edges. This should separate the sheets and allow some of the static electricity to dissipate. Our Weatherproof Polyester for Laser was tested well across multiple printer models, including desktop units and large digital presses.
