How to use

Turn off the printer and open the ribbon compartment according to the printer manufacturer’s instructions. Remove the worn ribbon cartridge by releasing any locking levers and lift it out. Unpack the new BLACKPOINT ribbon cassette, avoiding contact with the ribbon surface to prevent contamination. Insert the cassette into the carriage or spool holders so that the ribbon feeds correctly across the print head. Advance the ribbon slightly if needed to ensure proper tension, close the compartment and power the printer on. Perform a test print to confirm alignment and print density.

Usage recommendations

Store unopened cartridges in a dry, cool place away from direct sunlight. If prints show faint or uneven characters, advance the ribbon to a fresh section or replace the cassette. Use original or compatible cartridges that match the printer’s specified ribbon format to avoid installation issues and maintain print quality.
