How to use
Turn off the printer power before replacing the ribbon cartridge. Open the printer cover, remove the empty or worn cartridge according to the printer manufacturer’s guidance, and insert the Asarto ribbon tape ensuring correct alignment with print head and spindles. Advance the ribbon slightly if needed to remove slack, then close the cover and restore power. Perform a test print to verify correct installation and adjust printer settings for density if available.
