Handling the cartridge carefully to protect the printhead, push the plugs
located on top of the cartridge into the chambers using an awl or other hard blunt object.

Following the instructions, insert the blunt filling tube as far as possible and inject the proper colour into each chamber. The slower you inject, the more ink the sponge will absorb.

Stop when ink appears at the fill opening. Pull back on the plunger slightly to prevent spillage. Caution: Overfilling will cause cross contamination of colours, ruining the cartridge.

Do not reseal the openings.

Set the cartridge upright on a non-absorbent surface for 24 hours then clean the contacts and printhead per instructions and install the cartridge into the printer as new. Run at least 2 printer cleaning cycles to return print quality to normal.
