Abstract

A technique is described whereby matrix printer actuators are positioned accurately so as to eliminate repetitious adjustments of the actuators in relation to the printing platen. Actuator barrels 1, as shown in Fig. 1, must be precisely positioned at an angle of 4.5Πso that the print wires 2 will print accurately upon impact in relation to the platen 3. In order to accomplish this, a metal insert 4, as shown in Fig. 2, is positioned at the tip of the actuator barrel 1. Also, at the junction of the actuator barrel 1 and the actuator bracket 5 is a spherical ball 6 which acts as a rear position locator. The actuator barrel 1, as shown in Fig. 3 with its locator ball 6, is then placed into a grid 7. The grid 7 is then positioned onto a mounting surface 8 and guide 9 in a casting 10.
