Abstract:
PROBLEM TO BE SOLVED: To provide a cleaning method and a control method, preventing printing quality deterioration caused from ink adhering to the surrounding of a nozzle opening of an inkjet.SOLUTION: A cleaning method in an inkjet method discharges ink from a plurality of nozzle discharge ports by pressurizing the ink in an ink chamber communicated with a nozzle. The nozzle cleaning method in the inkjet method includes a suction step of sucking the ink from the nozzle discharge port into the inside, and an overflow step of drawing the ink from the nozzle discharge port to the outside. In the suction step, a pressure force is decreased so as not to allow air to go into from the nozzle discharge port, and in the overflow step, a pressure force is increased so as not to allow the ink to jump out from the nozzle discharge port.
