Abstract
An ink jet head cartridge include an ink container and a porous material contained in the container for retaining the ink. A process for filling the ink container includes the steps of supplying ink in a quantity greater than that which the porous material can retain through a first port and removing through a second port at least a quantity of ink which the porous material cannot retain. The process can also be performed through a single port. At least one of the ports can also be used for communicating with a recording head portion of the cartridge.
