of course, you know the centrifugal force trick, right?

Elimination of Air Pockets Using Centrifugal Force

Some of the sponge filled cartridges can develop air pockets at the bottom of the cartridge that can block the flow of ink. HP color cartridges and Epson Stylus Color cartridges are best known for this problem. A possible remedy is the use of centrifugal force.

Wrap the cartridge in a towel or cloth. Place the cloth wrapped cartridge in a plastic bag, (a plastic ‘grocery’ bag is good). Hold it in your hand with the head or exit ports pointing down. Extend your arm and swing the cartridge down towards the floor rapidly, as if you were going to throw it. Repeat several times, then remove the cloth wrapping. There should be a visible spot of ink from each of the chambers. If not, repeat this process..
