Liquid discharge apparatus

A liquid discharge apparatus comprising:

• a head including a nozzle, a pressure chamber communicating with the nozzle, and a pressure generation unit configured to cause a pressure change in liquid in the pressure chamber;
• a drive signal generation section configured to repeatedly generate a first drive signal including a plurality of drive pulses in a repetition cycle and a second drive signal including a plurality of drive pulses in the repetition cycle, the first drive signal being in synchronism with the second drive signal;
• and
• a drive controller configured to supply a pulse selected from the plurality of drive pulses included in the first drive signal or the second drive signal to the pressure generation unit, wherein
• the plurality of drive pulses include
• a first discharge pulse and a second discharge pulse that generate the pressure change so as to discharge liquid from the nozzle and
• a first micro-vibration pulse and a second micro-vibration pulse that generate the pressure change so as not to discharge liquid from the nozzle,
• the first drive signal includes one of the first discharge pulse and the first micro-vibration pulse in a first period included in the repetition cycle and includes one of the second discharge pulse and the second micro-vibration pulse in a second period included in the repetition cycle and later than the first period,
• the second drive signal includes the other of the first discharge pulse and the first micro-vibration pulse in the first period and includes the other of the second discharge pulse and the second micro-vibration pulse in the second period, and
• a length of a period from a start of the first period to a start of the first micro-vibration pulse differs from a length of a period from a start of the second period to a start of the second micro-vibration pulse.
