Abstract
A solvent consumption amount in head cleaning is reduced, and the convenience of an inkjet recording apparatus is enhanced. An inkjet recording apparatus is a continuous inkjet recording apparatus including: a print head that accommodates a nozzle, a charging electrode, a deflection electrode, and a gutter therein; an ink supply unit that supplies ink to the print head; a solvent supply unit that supplies a solvent to the print head; and a control unit that controls ink supply from the ink supply unit to the print head and controls solvent supply from the solvent supply unit to the print head, in which the print head includes an assist unit that assists cleaning when cleaning a component accommodated inside the print head with a solvent supplied from the solvent supply unit.
Claims20
A continuous inkjet recording apparatus comprising:
- a print head that accommodates therein, a nozzle that ejects particulate ink, a charging electrode that charges the particulate ink ejected from the nozzle, a deflection electrode that deflects a flying direction of the ink charged by the charging electrode, and a gutter that recovers ink not deflected by the deflection electrode, and ejects the ink deflected by the deflection electrode to an outside;
- an ink supply unit that supplies ink to the print head;
- a solvent supply unit that supplies a solvent to the print head;
- and
- a control unit that controls ink supply from the ink supply unit to the print head, and controls solvent supply from the solvent supply unit to the print head, wherein
- printing is performed by causing the ink ejected from the print head to land on a printing target object, and
- the print head includes an assist unit that assists cleaning of a component accommodated inside the print head when the cleaning is performed by a solvent supplied from the solvent supply unit.
An inkjet recording system comprising:
- a continuous inkjet recording apparatus including:
- a print head that accommodates therein, a nozzle that ejects particulate ink, a charging electrode that charges the particulate ink ejected from the nozzle, a deflection electrode that deflects a flying direction of the ink charged by the charging electrode, and a gutter that recovers ink not deflected by the deflection electrode, and ejects the ink deflected by the deflection electrode to an outside;
- an ink supply unit that supplies ink to the print head;
- a solvent supply unit that supplies a solvent to the print head;
- and a control unit that controls ink supply from the ink supply unit to the print head, and controls solvent supply from the solvent supply unit to the print head, printing being performed by causing the ink ejected from the print head to land on a printing target object;
- and
- a cleaning apparatus mounted to the print head and including an assist unit that assists cleaning when cleaning a component accommodated inside the print head with a solvent supplied from the solvent supply unit.
