A technique is described whereby a mechanism enables ink jet print head components to be accurately assembled. Utilization of the mechanism simplifies the manufacturing assembly operations by providing a means of holding, inserting and aligning critical parts during the assembly of ink jet print heads. The mechanism consists of a driver assembly tool for assembling the print head and a tube carrier device, used to insure the proper mounting and alignment of ink jet tubes. The carrier device, as shown in Fig. 1, contains the required number of holes, precisely spaced so as to align and retain piezo- electric ceramic (PEC) tubes used in the ink jet operation of the printer. The holes are tapered at one end to ease dispensing of tubes. The taper tends to reduce drag during PEC tube insertion at assembly.
