Abstract
The liquid discharge apparatus includes a liquid discharge head having nozzles formed therein, to discharge liquid from the nozzles and a cap to contact with or separate from the liquid discharge head to maintain the liquid discharge head. The liquid discharge head includes a common chamber connected to the nozzles, a liquid supply port provided at one end of the liquid discharge head in a longitudinal direction of the liquid discharge head to supply liquid to one end of the common chamber, and a liquid discharge port provided at another end of the liquid discharge head in the longitudinal direction to discharge liquid, which flows through the common chamber and is not discharged from the nozzles, from another end of the common chamber. The cap includes a drainage supply port to be connected with the liquid discharge port of the liquid discharge head with a connection path.
