ABSTRACT:
A parallel thermal ink jet printing device is produced by assembling a plurality of modules on a frame or base plate. Each of the modules is tested beforehand both from the electrical point of view and from the hydraulic point of view. In order also to allow for testing from the hydraulic point of view, each module is provided with an associated respective reservoir capable of being filled with a certain quantity of ink before the said module is assembled with the rest of the device. The reservoir preferably forms an appendix to the module capable of being inserted in a corresponding opening formed in the frame of the device so as to allow for precise alignment of the ink ejection nozzles provided on the various modules.
