A printhead includes a printhead module, a printhead frame, and an alignment assembly. The printhead module includes a plurality of nozzles adapted for emitting liquid from the printhead module. The alignment assembly aligns the printhead module and the printhead frame relative to each other and includes a base plate, a locator plate, a first set of locating elements, and a coupling member. The base plate includes a surface. The locator plate includes a plurality of through holes positioned relative to each other on a surface of the locator plate. The locator plate is affixed with the base plate such that a plurality of pockets are formed with each pocket having a wall corresponding to a wall of one of the through holes and a base corresponding to a surface of the base plate. Each of the locating elements of the first set are positioned with an interference fit in a respective one of the pockets. The walls of the pockets define positions of the locating elements of the first set relative to one another in a plane of the surface of the locator plate. The bases of the pockets define positions of the locating elements of the first set relative to one another in a direction normal to the surface of the base plate. The coupling member includes a second set of locating elements with each of the locating elements of the second set adapted for contact with one the locating elements of the first set. |
