Abstract:
1. A liquid discharge method for discharging a liquid with a head, the head comprising a plurality of nozzles, a liquid discharge section associated with one of each nozzle, a discharge deflection amount calculation circuit, a data table for defining the discharge deflection amount of the liquid to be discharged from each nozzle, and a discharge deflection means associated with each liquid discharge section, each discharge deflection means comprising two adjacent devices configured to emit energy, the liquid discharge method comprising the steps of: continuously detecting a distance between a liquid discharge surface of the head and a liquid landing surface of a liquid discharge target when the direction of the liquid discharge from a nozzle of each of the liquid discharge sections is to be deflected and sequentially transmitting the distance to the discharge defection amount calculation circuit; determining an amount of liquid discharge deflection in accordance with the result of the distance detection for each of the liquid discharge sections via the discharge deflection amount calculation circuit for the liquid corresponding to the liquid discharge section from (1) said detected distance, (2) the liquid landing target position, and (3) a predetermined discharge deflection amount in the data table; generating a heat timing differential between the adjacent devices configured to emit energy effective to deflect the direction of a liquid within the liquid discharge section to a desired deflection angle; and discharging the liquid within the discharge sections at the desired deflection angle, and then discharging the liquid via the nozzle.
