Abstract

The ink jet print head includes a plurality of modules in a stacked construction or a single module. The modules are disposed in a housing. The nozzle faces of the modules protrude into associated slits of a base plate of the housing, and the modules are electrically connected to a bus adapter. The modules are pressed, by means of a spring element and a common adapter for their ink connection stubs, against an end face of the slits and against the base plate. The assembly is self-adjusting, and its accuracy depends only on the dimensional accuracy of the base plate, the spring element, and a side edge of the modules which is in effect a reference edge.
