ABSTRACT:
A drive method for an ink ejection device that cancels residual pressure fluctuations using a signal drive power source, wherein at time (b) a positive voltage V from a single power source is applied to an ink chamber 4b1 and other ink chambers 4 are connected to ground. Therefore, the volume of ink chamber 4b1 increases from a natural volume. At time (c), voltage V applied to the ink chamber 4b1 is stopped and a positive voltage V from the single power source is applied to the other ink chambers 4 so that the volume in the ink chamber 4b1 is reduced from the increased volume to an extent beyond the natural volume that causes an ink droplet to be ejected from the nozzle 12 of ink chamber 4b1. At timing (d), application of positive voltage V to the ink chambers 4c0, 4a1, 4c1, 4a2, 4b2, and 4c2 is stopped so that all the ink chambers revert to the natural volume.
