placing the septum in a radial-compressed state during the inserting the septum into the septum receiving chamber; contacting an inner diameter of the septum receiving chamber with an outer diameter of the septum and maintaining the septum in the radial-compressed state in the septum receiving chamber; and inserting a septum cap onto an end portion of the housing member, including contacting the septum with the septum cap, contacting the inner diameter of the septum receiving chamber with an outer diameter of a first portion of the septum cap, and extending a flange of a second portion of the septum cap over the end portion of the housing member. ### Claim 2 (depends on 1) The method according to claim 1, further comprising: ultrasonic welding the septum cap to the end portion of the housing member. ### Claim 3 (depends on 1) The method according to claim 1, wherein the septum has a radial-uncompressed state and the radial-compressed state, a first septum portion having a first septum diameter, and a second septum portion having a second septum diameter less than the first septum diameter and disposed adjacent to the first septum portion such that the first septum diameter and the second septum diameter are smaller in the radial-compressed state than in the radial-uncompressed state. ### Claim 4 (depends on 3) The method according to claim 3, wherein the septum receiving chamber comprises: a first chamber portion having a first chamber diameter less than the first septum diameter in the radial-uncompressed state; a second chamber portion having at least a second chamber diameter less than the first chamber diameter and the second septum diameter in the radial-uncompressed state, the second chamber portion disposed adjacent to the first chamber portion; and a ledge portion disposed between the first chamber portion and the second chamber portion and having an inclined surface increasing in height along an inwardly direction, wherein the first chamber portion is configured to hold the first septum portion of the septum in the radial-compressed state and the second chamber portion is configured to hold the second septum portion of the septum in the radial-compressed state. ### Claim 5 (depends on 1) The method according to claim 1, wherein the septum receiving chamber comprises: a first chamber portion having a first chamber diameter; and a second chamber portion having a second chamber diameter less than the first chamber diameter, wherein the second chamber diameter is defined at an intersection of a ledge portion having an inclined surface increasing in height along an inward direction and opposite sidewalls diverging along a downstream direction. ### Claim 6 A fluid interconnect system usable with an image forming apparatus, the fluid interconnect system comprising: a fluid supply; a housing member extending in an axial direction, the housing member to supply fluid from the fluid supply to the image forming apparatus in a downstream direction; a septum receiving chamber formed within the housing member; a septum disposed within the septum receiving chamber in a radial-compressed state, an outer diameter of the septum fit within and in contact with an inner diameter of the septum receiving chamber; and a septum cap inserted onto an end portion of the housing member, the septum cap in contact with the septum and an outer diameter of a first portion of the septum cap fit within and in contact with the inner diameter of the septum receiving chamber and a flange of a second portion of the septum cap extended over the end portion of the housing member. ### Claim 7 (depends on 6) The fluid interconnect system according to claim 6, wherein the septum receiving chamber comprises: a first chamber portion having a first chamber diameter; a second chamber portion having a second chamber diameter less than the first chamber diameter, the second chamber portion disposed upstream from the first chamber portion; and a ledge portion disposed between the first chamber portion and the second chamber portion. ### Claim 8 (depends on 7) The fluid interconnect system according to claim 7, wherein the second chamber portion is formed by opposite sidewalls of the housing member spaced apart by a distance that decreases along an upstream direction. ### Claim 9 (depends on 8) The fluid interconnect system according to claim 8, wherein each of the opposite sidewalls form an angle of approximately 15 degrees with respect to a longitudinal axis of the housing member. ### Claim 10 (depends on 7) The fluid interconnect system according to claim 7, wherein the ledge portion has an inclined surface increasing in height along an inward direction. ### Claim 11 (depends on 6) The fluid interconnect system according to claim 6, wherein the septum receiving chamber comprises: a first chamber portion having a first chamber diameter; and a second chamber portion having a second chamber diameter less than the first chamber diameter, wherein the second chamber diameter is defined at an intersection of a ledge portion having an inclined surface increasing in height along an inward direction and opposite sidewalls increasing in spacing along a downstream direction. ### Claim 12 A fluid interconnect member usable with an image forming apparatus, the fluid interconnect member comprising: a housing member extending in an axial direction, the housing member configured to supply fluid from a fluid supply to the image forming apparatus in a downstream direction; a septum receiving chamber formed within the housing member and configured to hold a septum in a radial-compressed state and receive a septum cap in contact with the septum, the septum receiving chamber including a first chamber portion having a first chamber diameter, a second chamber portion having a second chamber diameter less than the first chamber diameter and disposed upstream from the first chamber portion, and a ledge portion disposed between the first chamber portion and the second chamber portion; wherein the second chamber portion has a cross-sectional area decreasing in an upstream direction, wherein the septum is to be inserted into an end portion of the housing member such that an outer diameter of the septum is in contact with an inner diameter of the first chamber portion of the septum receiving chamber, and wherein the septum cap is to be inserted onto the end portion of the housing member such that an outer diameter of a first portion of the septum cap is in contact with the inner diameter of the first chamber portion of the septum receiving chamber and a flange of a second portion of the septum cap extends over the end portion of the housing member. ### Claim 13 (depends on 12) The fluid interconnect member according to claim 12, wherein the ledge portion has an inclined surface increasing in height along an inward direction. ### Claim 14 (depends on 13) The fluid interconnect member according to claim 13, further comprising: an energy director disposed on the end portion of the housing member, the energy director configured to couple to the septum cap. ### Claim 15 (depends on 13) The fluid interconnect member according to claim 13, wherein the energy director is coupled to the septum cap through ultrasonic welding. ### Claim 16 (depends on 12) The fluid interconnect member according to claim 12, further comprising: the septum disposed in the septum receiving chamber in the radial-compressed state. ### Claim 17 (depends on 16) The fluid interconnect member according to claim 16, further comprising: the septum cap disposed downstream of the septum and in contact therewith. ### Claim 18 (depends on 12) The fluid interconnect member according to claim 12, wherein the ledge portion has an inclined surface increasing in height along an inward direction, and wherein the second chamber diameter of the second chamber portion is defined at an intersection of the ledge portion and opposite sidewalls of the second chamber portion increasing in spacing along a downstream direction.
