Patent ID: 8104854

Claim:
A liquid-droplet jetting apparatus which jets liquid droplets of a liquid onto a medium, the apparatus comprising: a head having an actuator which applies a pressure to the liquid and a plurality of nozzles which jet the liquid droplets; a carriage which is provided with the head and which moves in a predetermined direction; and a controller which performs a first control in which a jetting drive pulse is supplied to the actuator so as to jet the liquid droplets from the nozzles onto the medium while the carriage moves in the predetermined direction; wherein the controller additionally performs a second control in which, while the carriage moves in the predetermined direction, a non-jetting drive pulse is supplied to the actuator so as to impart vibration to a meniscus of the liquid in the vicinity of the nozzles without jetting the liquid droplets from the nozzles; wherein the controller controls the carriage to move reciprocally, in an outgoing route and a returning route, in the predetermined direction; wherein the controller performs the first control while the carriage moves in at least one of the outgoing route and the returning route; wherein the controller performs the second control continuously during a period, encompassing an entire time from start to stop of a continuous movement, in which the carriage moves in at least one of the outgoing route and the returning route, without performing the first control during the period.
