PRINT HEAD ASSEMBLY ACCELERATION CONTROL METHOD ABSTRACT OF THE INVENTION A control method for providing an acceptable motion window (range) that restricts high accelerations and velocities of an ink jet print head. The method provides two limited step ranges that are initiated dependent on the total distance that the print head is to be moved. If the distance is outside of the window range, a first step is used to bring the print head to e position which is a fixed second step from the final position. By limiting the print head's motion in each step range, the excitation of the fluid (ink) system is limited. With the first step completed, a second step range is used to drive the print head to the final position. If the initial distance is within the window range, the second step range is selected to drive the print head. The method is implemented with a computer program and print head position signals.
