Drive method of liquid discharging head and liquid discharging apparatus
Abstract:
Provided is a drive method of a liquid discharging head including a first step of acquiring physical property information indicating a physical property of liquid in the liquid discharging head, a second step of determining a waveform of a drive signal based on the physical property information, a third step of forming a first liquid column by supplying a first waveform, which is included in a first drive signal among the drive signals having the waveforms determined in the second step, to a drive element, and a fourth step of, when the first liquid column is formed, forming a second liquid column by supplying a second waveform, which is included in a second drive signal among the drive signals having the waveforms determined in the second step, to the drive element, and thereafter discharging a part or all of liquid constituting the second liquid column as a droplet.
