Droplet ejection apparatus

A droplet ejection apparatus used for a recording operation in which a droplet of a liquid is ejected on a recording medium, comprising:

• a recording head including (a) a nozzle from which the droplet of the liquid is ejected, (b) a pressure chamber which is filled with the liquid and whose volume is changeable for ejecting the droplet from the nozzle, and (c) an actuator which changes the volume of the pressure chamber by a drive pulse inputted thereto;
• and
• an operating device which outputs the drive pulse to the actuator, and
• wherein the operating device is capable of performing a restoring operation for restoring a droplet ejection performance of the recording head, the restoring operation including:
• a first operation for outputting, a plurality of times, an ejection drive pulse as the drive pulse by which the droplet can be ejected;
• and a second operation for outputting, a plurality of times, a non-ejection drive pulse as the drive pulse by which the droplet can not be ejected, the second operation being performed following the first operation.
