Abstract: An ink tank cartridge has a housing with a bottom wall and first and a divider that separates a housing cavity into second chambers. An ink supply port with an opening extends through and projects from the bottom wall. A porous member is accommodated in one of the chambers and abuts the opening in the ink supply port. The other chamber is partially filled with ink to a pre-determined level. The predetermined level is approximately 2 millimeters above the opening in the bottom wall in a preferred arrangement. The predetermined level is used to prevent excessive flow of ink through the opening in the bottom wall. A groove is formed in the bottom wall to direct and transfer ink from the porous member to the ink supply port.
