How to use
Before installation, remove the cartridge from its packaging and gently shake it once to distribute the ink evenly. Follow the printer manufacturer’s instructions to open the cartridge access panel, remove the empty cartridge and insert the Prism LC-421BK XL until it clicks into place. After installation, run a test page or printer alignment if recommended by the printer to ensure proper print quality.
