Abstract
A liquid discharge apparatus includes a discharge section having a driving element that is driven with a driving signal. When the temperature detected by the temperature detector is a first temperature, the driving signal includes a first driving waveform. The first driving waveform includes within one cycle, N number of first discharge pulses and N−1 number of first connection components each connecting two adjacent first discharge pulses where N is not less than three. Each of the N number of first discharge pulses is a pulse whose potential changes to effect a change in a pressure of liquid within a pressure chamber such that a liquid droplet can be discharged from a nozzle. Each of the N−1 number of first connection components is a component maintained at a constant potential for a time period longer than or equal to 0.6 times a natural vibration period of the pressure chamber.
