Abstract:
A liquid discharging device detects, among a plurality of nozzles of a liquid discharging head, a normal-discharging nozzle and a false-discharging nozzle, selects whether to recover discharging performance of the false-discharging nozzle by a cleaner or to compensate deterioration in an image caused by the false-discharging nozzle by a compensator using the normal-discharging nozzle according to the detected number of consecutive false-discharging nozzles, and performs operation according to the selection.
