ABSTRACT:
According to a method of controlling a head in an image recording apparatus, a valve body made of a diaphragm is brought into tight contact with a valve seat having a nozzle hole. Pressurized ink is supplied to a contact portion between the valve body and the valve seat. A gap formed between the valve body and the valve seat upon supply of the pressurized ink is controlled by an actuator. The pressurized ink is discharged from the nozzle hole through the gap controlled by the actuator.
