Abstract:
A liquid discharge head includes an actuator and a drive circuit. The actuator is configured to expand and contract a pressure chamber corresponding thereto. The drive circuit is configured to, during a dot formation cycle apply a first discharge pulse to the actuator to cause a first droplet to be discharged from the pressure chamber, and after a predetermined rest period, during which no discharge pulse is applied to the actuator, has elapsed from application of the first discharge pulse, apply a second discharge pulse to the actuator to cause a second droplet to be discharged from the pressure chamber.
