How to use

Turn off the label printer and open the cartridge compartment.

Usage recommendations

Avoid prolonged exposure to direct sunlight, high humidity or outdoor weather if long-term durability is required. Store spare cartridges in a cool, dry place away from direct sunlight and sharp objects.
