Abstract: A seal for an outlet port of an ink tank, the seal includes a seal member; and a seal retainer having a housing for the seal member; a first hook on a first side of the seal retainer; a second hook on a second side of the seal retainer, the second side being opposite the first side; a handle including a free end and a hinged end opposite the free end; and a hinge member disposed between the housing and the free end of the handle, wherein a distance between the free end of the handle and the hinged end of the handle is greater than a distance between the hinged end of the handle and an end of the seal retainer that is opposite the free end of the handle.

Abstract: An ink tank for an inkjet printhead, the ink tank includes an outlet wall having an outlet port for providing ink; a lead end wall disposed proximate the printhead when installation of the ink tank begins; a trail end wall that is opposite the lead end wall and that is configured to be distal to the printhead when installation of the ink tank begins; a first side wall extending from the lead end wall to the trail end wall and intersecting the outlet wall; and a second side wall opposite the first side wall, wherein first side wall and the second side wall each include a first indentation disposed at a first distance from the outlet wall; a second indentation disposed at a second distance from the outlet wall, the second distance being greater than the first distance; and a ledge disposed between the first indentation and the second indentation.

Abstract: A seal includes a seal member; and a seal retainer having a housing for the seal member, the housing including a first thickness near a first end and a second thickness near a second end, wherein the first thickness does not equal the second thickness; a wall extending from the first end of the housing, the wall including a latch opening; a first hook on a first side of the seal retainer; and a second hook on a second side of the seal retainer, the second side being opposite the first side, wherein the first hook and second hook are disposed proximate the second end of the housing, and wherein a force applied to the seal member by the housing near the first end is equal to a force applied to the seal member by the housing near the second end when the seal is assembled onto the ink tank.
