摘要： A recording head includes a nozzle orifice, a pressure chamber communicated with the nozzle orifice, and an actuator which varies a volume of the pressure chamber. A drive signal generator generates a drive signal in which a plurality of drive pulses are arranged within a unit recording period. The drive pulses includes at least a first drive pulse composed of an expanding element, which drives the actuator so as to expand the pressure chamber, an expansion holding element, which drives the actuator such that the expanded state of the pressure chamber is held in a first time period roughly equal to a first natural vibration period which is a natural vibration period of ink stored in the pressure chamber, and an ejecting element, which drives the actuator so as to contract the pressure chamber so that the ink in the pressure chamber is ejected from the nozzle orifice.

摘要： The drive signal supplied to the piezoelectric vibrator includes the expansion waveform elements (P1, P2, and P3) for expanding the pressure generating chamber, the contraction waveform element (P5) for contracting the pressure generating chamber expanded by the expansion waveform element and jetting an ink drop from the nozzle opening, and the vibration damping waveform element (P7) changing from the terminal voltage (VL) of the contraction waveform element (P5) to the vibration damping voltage (VM) so as to suppress the residual vibration of the meniscus of the pressure generating chamber after jetting an ink drop. The initial and terminal voltages of the drive signal are equal to each other and equivalent to the standby voltage (VL) set as a voltage of the piezoelectric vibrator at the time of non-supply of the drive signal. The vibration damping voltage (VM) lies between the standby voltage VL and the maximum voltage VH of the drive signal. Accidental jetting of ink drops, at the time of recovery of the vibrator voltage using the voltage recovery device, can surely be prevented.

摘要： A recording head is provided with a pressure chamber communicated with a nozzle orifice from which an ink droplet is ejected, and a vibration plate which constitutes a part of the pressure chamber. A pressure generating element deforms the vibration plate to vary a volume of the pressure chamber. A drive signal generator generates a drive signal for driving the pressure generating element. The pressure generating element is driven such that the pressure chamber is contracted so as to push out a meniscus of ink from the nozzle orifice such an extent that an ink drop is not ejected therefrom. Then the pressure chamber is expanded so as to pull the pushed-out meniscus toward the pressure chamber. Then the pressure chamber is contracted and held in the contracted state to eject an ink droplet from the nozzle orifice.
