发明名称 Droplet ejection apparatus
摘要 A droplet ejection apparatus comprises: (a) a recording head (30) including a nozzle (15) from which a droplet of a liquid is ejected, (b) a pressure chamber (16) which is filled with the liquid and whose volume is changeable for ejecting the droplet from the nozzle, and (c) an actuator (31) 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 which is capable of performing a restoring operation for restoring a droplet ejection performance of the recording head. The restoring operation includes: a first operation for outputting, a plurality of times, an ejection drive pulse as the drive pulse (50D) by which the droplet can be ejected; and a second operation for outputting, a plurality of times, a non-ejection drive pulse (50E) as the drive pulse by which the droplet can not be ejected, the second operation being performed following the first operation.
