LIQUID EJECTION APPARATUS, CONTROL METHOD THEREOF, AND PROGRAM

Abstract

To provide a liquid discharge device that can reduce poor discharging due to drying of liquid, while reducing power consumption.SOLUTION: A liquid discharge device 10 comprises a head 20 which has a nozzle 21 for discharging liquid and a driving element 23 for applying pressure to liquid in the nozzle 21, a tank 14 for storing liquid, a circulation flow passage 17 connected thereto so that liquid is circulated between the head 20 and the tank 14, a circulation pump 26c provided in the circulation flow passage 17, and a control device 30. The control device 30 executes: non-discharging flushing processing for driving the driving element 23 while preventing the nozzle 21 from discharging liquid so as to perform non-discharge flushing; switching processing for switching ON and OFF states of the circulation pump 26c; and determining processing for determining a frequency of non-discharge flushing in accordance with the flow volume of circulated liquid that is varied by switching the ON and OFF states of the circulation pump 26c by the switching processing.SELECTED DRAWING: Figure 1
