Using the eyelet screw provided, increase the size of the vent hole at the top of the cartridge.

Slowly inject up to 20ml of ink into the fill hole, inserting the blunt filling tube as far as possible. Do not reseal the vent hole when finished.

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.
