Abstract

This inkjet recording apparatus is provided with: a plurality of heads (3) that discharge the same color of ink onto a recording medium; an ink tank (84) that stores ink to be supplied to each of the plurality of heads; and a fluid delivery unit (850) that delivers ink from the ink tank to the head side. Each of the heads includes a manifold that is filled with ink and a first and a second ports (341, 342) in communication with the manifold (34) . Ink flow paths respectively connected to the first port and the second port of each head are fitted with open / close switchable valves (874, 875), and a control unit (9) that individually controls the opening and closing of the valves respectively connected to the first and the second ports of each head is provided. The heads can discharge ink individually such that maintenance can be performed quickly while ink consumption is suppressed.

Description

technical field [0001] The present invention relates to an inkjet recording device having an ink supply device for supplying ink to an inkjet head. Background technique [0002] As a recording device capable of forming images on various recording media such as plain paper and plastic sheets, there is an inkjet printer. An inkjet printer has an inkjet head that ejects ink from nozzle holes. An image is formed on the recording medium by ejecting ink as fine droplets from the nozzle holes of the inkjet head toward the recording medium. [0003] The inkjet head is connected to a cartridge storing ink, and ink is supplied from the cartridge to the inkjet head. [0004] At this time, if the ink is mixed with dissolved gas, air bubbles, or foreign matter such as dust is mixed in the ink, it will become the cause of poor ejection. head for maintenance. [0005] When maintaining the inkjet head, make the cover shell of the gland part that is arranged at the initial position close...
