ABSTRACT:
A method of refilling an ink jet cartridge with ink. The cartridge has a housing which encloses an internal ink reservoir extending between top and bottom ends thereof, an ink fill aperture extending through the housing near its top end, and a means for sealing the ink fill aperture. The cartridge further includes a bladder in the reservoir, an air port affixed to the top of the housing, and a spring means which biases the bladder toward a minimum volume state. According to the method, the cartridge is positioned with its top end above its bottom end, the ink fill aperture is unsealed, and the air port is sealed. The bladder is inflated to establish an internal volume in a predetermined range. Ink is then injected into the reservoir through the ink fill aperture. The ink fill aperture is then sealed, and the air port unsealed.
