Method for Controlling Inkjet Recording Device

A method for controlling an inkjet recording device comprising:

• providing a print head that receives a supply of ink to perform printing;
• providing a main body that includes an ink container to contain the ink and a solvent container to contain a solvent, and that supplies the ink in the ink container to the print head;
• wherein
• the print head includes a nozzle that discharges the ink as ink particles, a charging electrode that charges the ink particles discharged from the nozzle a deflection electrode that changes a flight direction of the charged ink particles, and a gutter that recovers the ink particles making no contribution to the printing,
• the inkjet recording device comprises a head cleaning unit in which the print head is set to clean the print head;
• providing a recovery container at the bottom portion of the head cleaning unit;
• detecting, using a sensor, whether or not the print head is set in the head cleaning unit;
• and
• controlling, using a control unit, the supply of ink;
• controlling, when the print head is set in the head cleaning unit, the supply of the ink to the nozzle and the recovery of the discharged ink from the gutter, wherein the gutter is located between the nozzle and recovery container;
• providing a plurality of ink circulation paths;
• and
• connecting, a pump to the circulation paths;
• and
• circulating, using the pump, the ink in a state where the print head is set in the head cleaning unit.
