Patent ID: 7658461

Claim:
An ink-jet recording apparatus comprising: an ink-jet head which includes: a channel unit having a plurality of nozzles and a plurality of pressure chambers that respectively communicate with the plurality of nozzles; a reservoir unit formed of a plurality of plates which are stacked on each other and disposed on the channel unit for supplying ink thereto, the reservoir unit having a recessed portion being formed in a lower surface of a lowermost one of the plurality of plates of the reservoir unit; and an actuator unit which is disposed on the channel unit and to which drive signals are applied, thereby changing a volume of the plurality of pressure chambers; a driver IC comprising a temperature sensor for detecting an environmental temperature of the actuator unit, and which includes a drive-signal generating portion for generating the drive signals to change the volume of the plurality of pressure chambers and for applying the generated drive signals to the actuator unit, the drive signals comprising ejection signals and non-ejection signals, each of the ejection signals for driving the actuator unit to eject ink from the plurality of nozzles and comprising at least one pulse, each of the non-ejection signals for driving the actuator unit without ejecting ink from the plurality of nozzles and comprising at least one pulse; and a control device arranged to execute a low-temperature-condition control by controlling the drive-signal generating portion to generate the non-ejection signals, where the environmental temperature detected by the temperature sensor is not higher than a prescribed first temperature, wherein the driver IC is disposed on the channel unit so as to be located adjacent to the actuator unit, and the actuator unit and the driver IC are accommodated in the recessed portion of the reservoir unit.
