Patent ID: 8690284

Claim:
A liquid discharge apparatus which discharges a liquid to a medium, comprising: a liquid discharge head having: a plurality of nozzles through which the liquid is discharged; a common chamber communicated with the nozzles and extending in an extending direction; a liquid chamber; a liquid supply port through which the liquid is supplied to a first end of the common chamber in the extending direction, and to the liquid chamber; and a communication channel which makes communication between the liquid chamber and the common chamber at a second end of the common chamber in the extending direction opposite to the first end; and a discharge control mechanism which is configured to control the liquid discharge head to perform a discharge operation of discharging the liquid from the nozzles to the medium; wherein the plurality of nozzles have a first nozzle group and a second nozzle group; wherein the discharge control mechanism controls the liquid discharge head to perform a flushing operation, as the discharge operation, so that the liquid is discharged from the first nozzle group in a discharge mode, which is different from a discharge mode of the second nozzle group, to generate a flow of the liquid in the communication channel; wherein the first nozzle group includes: a first nozzle subgroup; and a second nozzle subgroup which is located farther away from the communication channel than the first nozzle subgroup; and wherein the discharge control mechanism is configured to control the liquid discharge head to perform the flushing operation of the second nozzle group after performing the flushing operation of the first subgroup which is located nearer to the communication channel than the second nozzle subgroup.
