How to use

Turn the printer off or follow the manufacturer’s cartridge-replacement procedure to access the cartridge slot. Remove any protective seals from the refill cartridge if present and insert the cartridge into the printer until it clicks or seats securely according to the printer’s guidance. After installation, run a test print or alignment procedure through the printer’s maintenance menu to confirm correct installation and print head alignment. Replace the cartridge when print density becomes faint or when the printer indicates low or empty ink status.

Usage recommendations

Store cartridges upright in a cool, dry place away from direct sunlight. Use within the manufacturer’s recommended shelf life for inks to avoid fading or clogging. For best results on important documents, allow prints to dry fully and perform periodic printhead cleaning if streaks or missing lines appear. Verify printer compatibility with HP 45 series cartridges before purchase.
