For use with the BradyPrinter i7100 Industrial Label Printer. Black silicone rubber coating for less print head wear on basic label materials. Using a roller of similar width as the media reduces wrinkling and extends print head life. Use with media width up to 114 mm wide. Rollers are easily changed-out using the on board hex key tool that ships with printer. Clean rollers often with IPA cleaning swabs and replace worn rollers to prevent damage to the print head.
