For use with the i7500 Industrial Label Printer. Rubber roller material recommended for high print accuracy on small and large labels. Using a roller of similar width as the media reduces wrinkling and extends printhead life. Use with media width up to 80 mm wide — use narrowest roller that covers the media width, and use narrowest ribbon that covers both media and roller. Rollers are easily changed-out using the included T-20 wrench that ships with all i7500 printer models. Clean rollers often with IPA cleaning swabs (#PCK-6) and replace worn or rough rollers to prevent damage to the printhead and optimize print quality.
