Abstract: A liquid discharge apparatus includes a liquid discharge head, circuitry, and an image detector. The liquid discharge head includes multiple nozzles and discharges a liquid from the multiple nozzles. The circuitry causes the liquid discharge head to discharge the liquid onto a recording medium to form an image in an image area of the recording medium in a printing operation. The image detector reads the image formed on the recording medium. The circuitry further causes the liquid discharge head to discharge the liquid onto at least one of a leading end or a trailing end of the recording medium to form a flushing pattern different from the image in a flushing operation, causes the image detector to read the flushing pattern, detect a defective part in the flushing pattern read by the image detector, and identify a defective nozzle among the multiple nozzles based on defective part.
