The jetting module includes a nozzle plate, mounting features, and fluid and electrical connections. The mounting features of the jetting module are configured to engage the mounting features of the printhead. The fluid and electrical connections of the jetting module correspond to the fluid and electrical connections of the printhead. The fluid and electrical connections of the jetting module are located relative to the mounting features of the jetting module such that a force applied to couple the fluid and electrical connections of the jetting module and the fluid and electrical connections of the printhead provides force to maintain contact between the mounting features of the jetting module and the mounting features of the printhead. ## Claims ### Claim 1 A jetting module for installation in a printhead of a printer, the printhead including a set of mounting features, a set of fluid and electrical connections, and at least a portion of a drop deflection mechanism, the jetting module comprising: a nozzle plate; a set of mounting features configured to engage the set of mounting features of the printhead; a set of fluid and electrical connections corresponding to the set of fluid and electrical connections of the printhead, the set of fluid and electrical connections of the jetting module being located relative to the set of mounting features of the jetting module such that a force applied to couple the set of fluid and electrical connections of the jetting module and the set of fluid and electrical connections of the printhead provides force to maintain contact between the set of mounting features of the jetting module and the set of mounting features of the printhead. ### Claim 2 (depends on 1) The jetting module of claim 1, wherein the nozzle plate is aligned relative to the set of mounting features of the jetting module. ### Claim 3 (depends on 1) The jetting module of claim 1, wherein the set of electrical connections of the jetting module include electrical connections on an electrical contact board that is float mounted to the jetting module. ### Claim 4 (depends on 1) The jetting module of claim 1, further comprising: an alignment feature to guide the set of fluid and electrical connections of the printhead such that fluid and electrical connections can be made between the jetting module and the printhead. ### Claim 5 (depends on 1) The jetting module of claim 1, wherein the set of mounting features of the jetting module are integrally formed in the jetting module. ### Claim 6 (depends on 5) The jetting module of claim 5, wherein the set of mounting features of the jetting module include a 2-2-2 mount. ### Claim 7 (depends on 5) The jetting module of claim 5, wherein the set of mounting features of the jetting module include a 3-2-1 mount. ### Claim 8 (depends on 1) The jetting module of claim 1, the set of mounting features of the jetting module defining a plane, wherein the force applied to couple the set of fluid and electrical connections of the jetting module and the set of fluid and electrical connections of the printhead is perpendicular to the plane. ### Claim 9 (depends on 1) The jetting module of claim 1, wherein the fluid connections of the jetting module are drip resistant. ### Claim 10 A jetting module for installation in a printhead of a printer, the printhead including a set of mounting features, a set of fluid and electrical connections, and at least a portion of a drop deflection mechanism, the jetting module comprising: a nozzle plate; a set of mounting features configured to engage the set of mounting features of the printhead; a set of fluid and electrical connections corresponding to the set of fluid and electrical connections of the printhead, the set of fluid and electrical connections of the jetting module being located relative to the set of mounting features of the jetting module such that a force applied to couple the set of fluid and electrical connections of the jetting module and the set of fluid and electrical connections of the printhead provides force to maintain contact between the set of mounting features of the jetting module and the set of mounting features of the printhead, wherein the set of mounting features of the jetting module include V-grooves. ### Claim 11 (depends on 10) The jetting module of claim 10, wherein the V-grooves include a material insert. ### Claim 12 (depends on 11) The jetting module of claim 11, wherein the material insert includes one of a hardened metal material and ceramic material.
