A magnetically preloaded air bearing motion system for an imaging system motion system includes a carriage for moving a scanning means along a rigid spar for reflecting an optical feed beam onto media. The carriage includes a pair of orthogonal walls for engaging the orthogonal walls of the spar and an air bearing system disposed therein. The air bearing includes a plurality of permanent magnets secured in a prearranged pattern to the orthogonal walls of the carriage for providing an attractive force to couple the carriage to the spar. The carriage further includes a series of passageways terminating at a plurality of output orifices arranged in a predetermined pattern on the orthogonal walls of the carriage. Compressed air is system is electrically connected to the linear motor for controlling the movement of the carriage along the spar.
