ABSTRACT:
The print head includes a print head support, a pair of actuators on one side of the support, and wire guide supports on the opposite side of the print head support for clamping the actuators and wire guide supports to the print head support. The wire guide supports have diameters equal to the centerline-to-centerline spacing of the print wires. The print head support has a linear surface extending perpendicular to a plane passing along the edges of the wire guide supports. The print heads are aligned along a support member by securing the print head support to the support member with the tangent plane and linear surface engaging mutually perpendicular surfaces on the support member whereby the contact between the wire guide supports along the support member establishes the centerline-to-centerline spacing of the print wires. The print head support is secured to the support member by a single bolt, thereby enabling removal of a defective actuator by removal of the support with the defective and a serviceable actuator for replacement.
