  • Publication number: 20210155001
    Abstract: Provided is an inkjet recording apparatus that causes a recording head to execute appropriate flushing based on the presence or absence of a non-ejecting nozzle in order to reduce deterioration of the image quality of recorded images or to improve the ejection failure of a non-ejecting nozzle at an early stage. When the recording head executes a first flushing, a control unit of the inkjet recording apparatus determines the presence or absence of a non-ejecting nozzle based on a detection result of an ejection detection unit. Then, based on the determination result, the control unit selects whether or not to perform a second flushing. In the second flushing, the recording head is caused to eject ink at timing at which a recording medium on the conveyor belt faces the recording head due to traveling of the conveyor belt.

  • Publication number: 20210138785
    Abstract: Provided is an inkjet recording apparatus that avoids deterioration of the image quality of recorded images due to flushing without reducing productivity even when the recording medium is placed at a position deviated from the normal position with respect to the opening of the transport belt. In the control unit of the inkjet recording apparatus, at least one recording medium is placed between two opening groups located in a preset pattern on a transport belt. In addition, based on the detection result of the second detection sensor, the recording medium supply unit supplies a plurality of recording media to the transport belt so that a tip of the leading recording medium is located at a specific position with respect to a reference opening group on the transport belt. This first control is performed.
