Abstract:
A droplet ejecting head includes a board, a pressure chamber, a nozzle, and an actuator configured to cause a pressure change in the pressure chamber in response to an electrical signal supplied from a drive circuit. The drive circuit is configured to set the electrical signal at a first voltage level, change the electrical signal to a second voltage level, set the electrical signal to a third voltage level during a time period after changing the electrical signal from the first voltage level to the second voltage level, the time period being equal to a primary natural oscillation period of the actuator when the pressure chamber and the nozzle are filled with solution, and set the electrical signal to the first voltage level after the time period has elapsed. The third voltage level is between the first and second voltage levels or equal to the second voltage level.
