ABSTRACT:
In an orifice band ink jet printer, smooth motion of an orifice band and its isolation from solid structures is desirable for uniform ink drop formation. But prior means for smoothly driving isolated movable members do not provide the precise synchronism of speed and phase in an aligned path which is needed for good image synthesis. Such precise and smooth motion is attained according to the invention by a servo system which includes a forced flow of liquid ink along the orifice band to provide a principal driving force and a rapidly responsing auxiliary drive to provide a supplemental force to maintain synchronous speed and phase of the orifice band. Occurrence times of a signal component which corresponds to a reference orifice location and of an actual sensed orifice location are processed by a computer to generate a speed error signal and a phase error signal, the speed error signal is substantially nulled by regulating flow of the liquid ink, and the phase error signal is precisely nulled by the auxiliary drive.
