摘要

A fluid ejecting apparatus that ejects fluid includes: a pressure chamber (13) that is filled with the fluid; a pressure generating element (17) that deforms a wall face of the pressure chamber to change a volume of the pressure chamber; a nozzle (15) that is in fluid communication with the pressure chamber and that is used for ejecting the fluid; and a control unit that generates a drive pulse for controlling the pressure generating element. The control unit is able to generate a maintenance drive pulse (300) for ejecting a bubble together with the fluid from the pressure chamber. The maintenance drive pulse includes a first pulse portion (Pwc) that drives the pressure generating element to cause the pressure chamber to expand into an expanded state and a second pulse portion (Pwd) that causes the pressure chamber to contract from the expanded state. The width of the second pulse portion is equal to or smaller than half the Helmholtz resonance period of the fluid with which the pressure chamber is filled.
