Abstract
An apparatus for driving an ink jet printer including actuators for first and second pressure chambers communicating with first and second nozzles, the printer operating in a first mode in which the first and second nozzles are permitted to eject a first and a second ink and in a second mode in which only the first nozzles are permitted to eject the first ink, the apparatus including an obtainer which obtains a mode signal indicating in which one of the first and second modes the printer is to operate, and image data indicating whether each of the first and second nozzles is to eject a corresponding one of the first and second inks; and an applier which applies, based on the signal and the data, a voltage to each actuator such that when the printer is to operate in the first mode, a first voltage not equal to zero V is applied to an actuator corresponding to an operative nozzle of the first and second nozzles that is to eject a corresponding one of the first and second inks and subsequently a first subsequent voltage based on the data is applied to the actuator corresponding to the operative nozzle of the first and second nozzles, and such that when the printer is to operate in the second mode, the first voltage is applied to an actuator corresponding to an operative nozzle of the first nozzles that is to eject the first ink and subsequently a second subsequent voltage based on the image data is applied to the actuator corresponding to the operative nozzle of the first nozzles, and a second voltage equal to zero V is applied to one or more actuators corresponding to the one or more second nozzles.
