Abstract
The present invention entails an accurate, sensitive, and stable means of mounting a print head to a movable carriage assembly of the type used in computer output printers. The invention uses one pair of planar mounting surfaces and one pair of angled mounting surfaces between the print head and the carriage of a print head assembly. A pair of pivoting clamping plates apply a force that urges both pairs of mounting surfaces together while simultaneously providing adjustment of the translation of the print head relative to the carriage. The translation across the oppositely angled surfaces on two of the four mounting surfaces provides an accurate azimuthal angle adjustment for the print head. Because the other mounting surfaces are in the same plane, the translation affects only the azimuthal angle.
