Abstract:
A liquid discharging device includes a liquid discharging head which discharges liquid. A drive signal generator generates a drive pulse. A liquid receiving portion faces a nozzle-formed surface of the liquid discharging head and receives discharged liquid. Electrical change information is acquired by detecting change in an electrical characteristic between a conductive portion of the liquid discharging head and the liquid receiving portion when liquid is discharged. Correlation information shows correlation between the electrical change information and temperatures of discharged liquid. The drive signal generator generates an information acquiring drive pulse. The correlation information shows correlation between the electrical change information obtained when discharging the liquid using the information acquiring drive pulse and the temperatures of the liquid. Based on the correlation information, the temperature of the liquid corresponding to the electrical change information is estimated as an estimated liquid temperature and the drive pulse is thereby corrected.
