Abstract:
A liquid ejection apparatus to eject liquid droplets includes an inkjet head that is an ejection head including a plurality of nozzles and a plurality of driving elements, a driving signal outputter, an ejection nozzle setter, and a timing setter to set timing at which the driving elements receive a driving signal. The driving signal outputter outputs, in common, a voltage change signal being a signal whose voltage changes with passage of time, as at least a part of the driving signal, to the plurality of nozzles. The timing setter individually sets, for each of the driving elements, a time period during which the driving elements receive the voltage change signal. The nozzles respectively eject liquid droplets by inkjet technology according to the driving signal in which the time period to receive the voltage change signal is individually set.

Claim (Index 3):
The liquid ejection apparatus according to  claim 2 , wherein\n the driving signal outputter outputs, as at least a part of the driving signal,\n a first pull signal that is a voltage signal causing the piezo element to be displaced so as to pull a liquid into an ink chamber of a preceding stage of the nozzle, \n a push signal that is a voltage signal causing the piezo element to be displaced so as to push out the liquid pulled in according to the first pull signal, and \n a second pull signal that is a signal causing the piezo element to be displaced so as to push back a part of the liquid pushed out of the nozzle according to the push signal, \n wherein each of the driving elements causes liquid droplets to be ejected from the nozzle corresponding to the driving element by sequentially receiving the first pull signal, the push signal, and the second pull signal, wherein the timing setter sets timing at which each of the driving elements receives the first pull signal, the push signal, and the second pull signal, and wherein the voltage change signal is at least one of the first pull signal, the push signal, and the second pull signal.
