How to use

Power off the printer before replacing the ribbon to avoid accidental movement of the print head. Open the printer cover, remove the spent cartridge according to the printer manual, and install the Asarto ribbon cartridge ensuring the ribbon is taut and correctly aligned with the print head path. Close the cover and run a test print or head alignment as recommended by the printer manufacturer to confirm proper installation and print quality.

Usage recommendations

Store unopened cartridges in a cool, dry place away from direct sunlight and high humidity. For best results, replace the ribbon when print density decreases or when printouts show streaking. Use original equipment guidelines for handling to avoid contact with the ribbon surface and to prevent contamination that could affect print quality.
