Liquid ejecting apparatus

A liquid ejecting apparatus comprising:

• a liquid ejecting head including a pressure chamber substrate having a plurality of pressure chambers, individual electrodes individually provided for the plurality of pressure chambers, a common electrode provided in common for the plurality of pressure chambers, a piezoelectric body disposed between the individual electrodes and the common electrode and configured to apply pressure to liquid within the pressure chambers, and a drive wiring electrically coupled to the individual electrodes and the common electrode;
• a controller that controls an ejection operation of the liquid ejecting head by applying a drive voltage to the individual electrodes and applying a reference voltage to the common electrode to drive the piezoelectric body;
• and
• an acquirer that acquires information related to a cumulative number of times of the driving of the piezoelectric body, wherein
• the controller drives the piezoelectric body such that, when the cumulative number of times of the driving is a first number of times, a voltage difference between the drive voltage and the reference voltage is a first value, and
• the controller drives the piezoelectric body such that, when the cumulative number of times of the driving is a second number of times greater than the first number of times, the voltage difference is a second value smaller than the first value,
• the liquid ejecting apparatus further comprising a detecting resistor that detects a temperature of the liquid within the pressure chambers, wherein
• the controller drives the piezoelectric body such that, when the cumulative number of times of the driving is the first number of times and the temperature detected by the detecting resistor is a first temperature, the voltage difference is a third value,
• the controller drives the piezoelectric body such that, when the cumulative number of times of the driving is the first number of times and the temperature detected by the detecting resistor is a second temperature higher than the first temperature, the voltage difference is a fourth value equal to or larger than the third value,
• the controller drives the piezoelectric body such that, when the cumulative number of times of the driving is the second number of times and the temperature detected by the detecting resistor is the first temperature, the voltage difference is a fifth value, and
• the controller drives the piezoelectric body such that, when the cumulative number of times of the driving is the second number of times and the temperature detected by the detecting resistor is the second temperature, the voltage difference is a sixth value larger than the fifth value.
