Abstract:
1. A fluid discharge device comprising: a discharge head configured to discharge a fluid from nozzle, the discharge head having a drive element that is configured to cause the fluid to be discharged from the nozzle; a nozzle inspection part configured to inspect a state of discharging of the fluid from the nozzle; and a controller configured to supply a pre-process drive signal to the drive element as a pre-process before executing an inspection process to inspect the state of discharging of the fluid using the nozzle inspection part, such that an unstable nozzle in an unstable state from which the fluid is unstably discharged is set in a dot omission state where discharging of the fluid from the unstable nozzle is avoided during the inspection process, the pre-process drive signal being set such that the fluid is discharged from a stable nozzle while the discharging of the fluid from the unstable nozzle is avoided.
