Patent number: 11964489Abstract: An inkjet recording apparatus includes a recording head including a plurality of nozzles for ejecting ink, a conveyor belt that has a plurality of apertures and conveys recording media one by one, a control unit, an ink receiver, and a pipe-shaped ink discharge flow path. The control unit controls drive of the recording head and the conveyor belt to perform flushing, in which the ink is ejected from the nozzle of the recording head to pass through one of the apertures, at a timing different from a timing contributing to image recording. The ink receiver is disposed to face the recording head sandwiching the conveyor belt therebetween, to receive the ink after passing through the aperture when the flushing is performed. The ink discharge flow path is connected to the ink receiver. When the flushing is performed, a predetermined amount of liquid is stored in the ink receiver.Type: GrantFiled: March 21, 2022Date of Patent: April 23, 2024Assignee: KYOCERA Document Solutions Inc.Inventors: Takashi Somete, Chikara Ishihara, Noriaki Furukawa, Takuma Araki, Jun Nakano, Hiroomi Nakatsuji, Issei Nakano
