Abstract
A liquid ejecting system includes a head unit that includes a pressure chamber, a drive element driven by an applied drive waveform, a vibration plate that vibrates by drive of the drive element, and a nozzle through which a liquid is ejected by a pressure applied in the pressure chamber by vibration of the vibration plate, and an input portion to which an input parameter for detecting an ejection failure of the liquid based on residual vibration of the vibration plate is input from a server through a network connection portion.

A liquid ejecting system comprising:
- a head unit that includes a pressure chamber, a drive element driven by an applied drive waveform, a vibration plate that vibrates by drive of the drive element, and a nozzle through which a liquid is ejected by a pressure applied in the pressure chamber by vibration of the vibration plate;
- and
- an input portion to which an input parameter for detecting an ejection failure of the liquid based on residual vibration of the vibration plate is input from a server through a network connection portion, the input parameter includes a first input parameter regarding a threshold value to be compared with a potential indicating an amplitude of the residual vibration, and the first input parameter is set so that the threshold value becomes smaller as deterioration of the drive element increases.
