Abstract

A plurality of nozzles 10 in an ink jet printer are connected, as shown in Figs. 1 and 2, to the pressure chamber or manifold 12 contained within complementary body and cover members 13 and 14 by flexible tubes 15. A piezoelectric crystal 17 is positioned in the chamber to provide synchronized drop formation. The nozzles are positioned in openings 16 in a support 18, where they are adjusted both vertically and horizontally by angularly related screws A and B positioned at 45 degrees to the vertical. A spring 24 below the nozzle provides preloading with overlapping the screws A, B and A', B' as shown schematically in Figs. 3 and 4. The packaging of the nozzles may be improved by pairing the screws and thus eliminating bending moments in the tubes at the points of aiming, as shown in Figs. 5 and 6.
