  • Liquid discharge apparatus, method and storage medium for computer-readably storing program therein
    Patent number: 8991961
    Abstract: An inkjet printer includes a liquid discharge head, a temperature sensor, and a controller. The controller changes a voltage waveform to be input to the ink discharge head, while a nozzle surface is facing a first gap. The temperature sensor measures a first actual temperature of the ink discharge head, while the nozzle surface is facing a second gap. The controller calculates, on the basis of the first actual temperature and a discharge history of ink discharged to a sheet located between the first gap and the second gap, a first estimated temperature of the ink discharge head corresponding to the time in which the nozzle surface is facing the first gap. The controller changes the voltage waveform on the basis of the first estimated temperature.
