Abstract
A liquid discharge apparatus includes heads to discharge a liquid; caps to contact and move away from the plurality of heads, respectively; individual drain passages communicating with the plurality of caps, respectively; at least one common drain passage communicating with at least two of the individual drain passages; suction devices provided in the individual drain passages, respectively; and a controller. Each of the individual drain passages is to allow and shut off communication between the cap and the common drain passage. The controller causes the individual drain passage to allow the communication between the cap and the common drain passage when performing capping and decapping of the head. The controller caps the sucking target with the cap after shutting off each individual drain passage communicating with the cap corresponding to the head that is not a sucking target.
