Toner Flaking Off and/or Incomplete Print Out When Using Polyester Label Or Tag Materials

Technical Support

Solution: Use the following steps to solve the problem:

  1. Different polyester label or tag materials materials have been optimized for use in various printers and copiers.
  2. Adjust the printer's print density to achieve optimum results. Refer to the printer's User's Manual for specific adjustment procedures for your printer.

Summary: The toner and printing process of Laserprinters has been optimized for printing on plain copy paper. When other types of media such as polyester label or tag materials are used, some degradation of print quality may occur. Tiny gaps may appear throughout the print on polyester label or tag materials. These "character voids" occur because the polyester label or tag materials material does not accept compression as well as paper and because the polyester label or tag materials material has a greater density.

If toner deposited on the page could be inspected closely, it would appear to be thicker in some areas than others, often where character strokes converge. When magnified, the thicker toner would look like small hills. As the polyester label or tag materials passes through the fuser, the toner is compressed and melted. Melting the toner not only allows it to adhere to the page but also allows it to adhere to other toner particles.

Polyester label or tag materials material is different from paper as it is more dense and it compresses less than plain paper as it passes through the fuser. The greater density affects the heat transfer rate of energy passing through the toner. Thicker areas of toner may not melt in the middle depths of the "hills". Unmelted toner does not stick to itself or the polyester label or tag materials.

By adjusting the print density correctly, when you run your fingernail over the toner it will be smooth (no bumps or hills) and will not smear.
