DRIVE CONTROLLING METHOD OF LIQUID-DROPLET DISCHARGING HEAD, DRIVE CONTROLLER OF LIQUID-DROPLET DISCHARGING HEAD AND LIQUID-DROPLET DISCHARGING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a drive controlling method of liquid-droplet discharging head capable of suppressing effectively the residual vibration of an electrostatic-actuator vibrating-plate section and preventing a surplus liquid-droplet from being discharged and performing a high-speed printing operation, a liquid-droplet discharging-head drive controller using the same method and a liquid-droplet discharging device. SOLUTION: After having applied a driving voltage pulse Pw which makes the liquid-droplet discharged, the vibrating plate part displaced by the residual vibration applies an auxiliary voltage pulse Pwa suppressing the residual vibration of the vibrating plate part to time zones t4-t7 with a rate or acceleration which makes the liquid running out of a nozzle further pressurized in the discharging direction.
