Abstract:
1. A liquid ejecting apparatus for ejecting liquid to a target, comprising: a liquid ejecting head operable to eject liquid; a recovery section operable to recover liquid-ejection ability of said liquid ejecting head by performing a recovery operation during which said liquid ejecting head discharges the liquid to a position different from the target; an accommodating section operable to accommodate waste liquid discharged from said liquid ejecting head during the recovery operation; a discharge controlling unit operable to control an amount of waste liquid discharged from said liquid ejecting head during the recovery operation; a time acquiring unit operable to acquire and memorize time from an external information processor; a first remaining amount counter operable to memorize a first remaining amount of waste liquid in association with the recovery-operation time acquired from said time acquiring unit; and a first remaining amount computing unit operable to compute a first evaporation amount of waste liquid that has been evaporated after a recovery operation performed at least one time ago based on difference between current recovery-operation time and time of the recovery operation performed at least one time ago, to compute the first remaining amount of the waste liquid after the current recovery operation by subtracting the first evaporation amount from the first remaining amount of the waste liquid memorized in said first remaining amount counter and adding an amount of waste liquid, which is discharged to said accommodating section during the current recovery operation, to the subtracted result, and to write the computed first remaining amount into said first remaining amount counter in association with the current recovery-operation time, when said time acquiring unit acquires the current recovery-operation time from the information processor.
