How to use

Before installation, remove the cartridge from packaging and carefully remove any protective tape as indicated. Power on the printer and open the cartridge access door; wait for the carriage to stop. Insert the cartridge into the correct slot and press until it clicks into place. Close the access door and follow any on-screen prompts to initialize the new cartridge or run a brief printhead alignment if the printer requests it. For best results, print a test page to confirm proper installation and print quality.

Usage recommendations

Store unused cartridges in a cool, dry place away from direct sunlight and extreme temperatures. Use within the manufacturer’s recommended shelf life for optimal performance. If prints show streaks or faded areas, run the printer’s cleaning routine and perform alignment. Replace the cartridge when print density declines or when the printer indicates low ink. For archival documents that require fade resistance over many years, consider printing on appropriate archival papers.
