Device for arranging a print head in a certain position, including: - a main unit comprising a main frame providing a primary abutting part and a support part (130, 130a, 130b); - a sub-unit comprising a sub-frame providing a secondary abutting part, a connecting member (230, 230a, 230b) movable relative to the sub-frame between a first position and a second position, and an urging member for urging the connecting member (230, 230a, 230b) from the second position towards the first position, and - a print head connectable to the connecting member (230, 230a, 230b) to form a sub-assembly (200, 300) with the sub-unit, wherein the main unit is configured to accommodate a sub-assembly (200, 300) formed by the sub-unit and the print head in a preliminary position in which, with the connecting member (230, 230a, 230b) in the first position, the print head contacts the support part (130, 130a, 130b), and the secondary abutting part is spaced apart from the primary abutting part, wherein the support part (130, 130a, 130b) is configured to mate with the print head to prevent lateral displacement of the print head relative to the main frame, wherein the sub-frame is movable relative to the main frame from the preliminary position towards a final position against a force exerted onto the sub-frame by the urging member while the connecting member (230, 230a, 230b) moves from the first position towards the second position against a force exerted onto the connecting member (230, 230a, 230b) by the urging member, under the influence of a force exerted onto the print head by the support part (130, 130a, 130b), wherein in the final position, the secondary abutting part abuts the primary abutting part, wherein the main unit is configured to hold a sub-assembly (200, 300) of the sub-unit and the print head with the nozzle face of the print head oriented in parallel to a plane defined by two orthogonal axes (X, Y), wherein the sub-unit is configured to move from the preliminary position towards the final position by a translation along an axis normal to said plane. - a main unit comprising a main frame providing a primary abutting part and a support part (130, 130a, 130b); - a sub-unit comprising a sub-frame providing a secondary abutting part, a connecting member (230, 230a, 230b) movable relative to the sub-frame between a first position and a second position, and an urging member for urging the connecting member (230, 230a, 230b) from the second position towards the first position, and - a print head connectable to the connecting member (230, 230a, 230b) to form a sub-assembly (200, 300) with the sub-unit, wherein the main unit is configured to accommodate a sub-assembly (200, 300) formed by the sub-unit and the print head in a preliminary position in which, with the connecting member (230, 230a, 230b) in the first position, the print head contacts the support part (130, 130a, 130b), and the secondary abutting part is spaced apart from the primary abutting part, wherein the support part (130, 130a, 130b) is configured to mate with the print head to prevent lateral displacement of the print head relative to the main frame, wherein the sub-frame is movable relative to the main frame from the preliminary position towards a final position against a force exerted onto the sub-frame by the urging member while the connecting member (230, 230a, 230b) moves from the first position towards the second position against a force exerted onto the connecting member (230, 230a, 230b) by the urging member, under the influence of a force exerted onto the print head by the support part (130, 130a, 130b), wherein in the final position, the secondary abutting part abuts the primary abutting part, wherein the main unit is configured to hold a sub-assembly (200, 300) of the sub-unit and the print head with the nozzle face of the print head oriented in parallel to a plane defined by two orthogonal axes (X, Y), wherein the sub-unit is configured to move from the preliminary position towards the final position by a translation along an axis normal to said plane.
