How to use

Turn on the printer and open the cartridge access cover following the printer manufacturer's instructions. Remove the used cartridge by pressing the release tab and gently pulling it out. Unpack the replacement cartridge, remove protective seals if present, and avoid touching the chip contacts or the nozzle area. Insert the cartridge into the correct colour slot until it clicks into place, then close the access cover. Allow the printer to recognise the cartridge; run a nozzle check or head alignment if recommended by the printer to ensure optimal output.

Usage recommendations

Store unopened cartridges in a cool, dry place and use within the manufacturer's recommended period for best results. For reliable print quality, perform periodic nozzle checks and run the printer's maintenance routines when replacing cartridges. Avoid prolonged storage of partially used cartridges outside the printer to reduce the risk of drying or clogging of the black ink.
