Claim 0:
1. A liquid discharge apparatus comprising:
a liquid discharge unit configured to discharge liquid from one or more liquid discharge port which is arranged on a discharge surface;
a cap capable of switching between a close state in which the cap covers the discharge surface and an open state in which the cap does not cover the discharge surface;
a waste liquid containing unit configured to contain a waste liquid of the liquid;
a mount unit configured such that the waste liquid containing unit is mounted to be attached/detached; and
a control unit configured to control a discharge operation of a liquid from the discharge unit,
wherein
the liquid discharge unit is capable of performing recording processing for discharging liquid from the one or more discharge port onto a recording medium and preliminary discharge operation for discharging liquid from the one or more discharge port to the cap, and
the control unit controls based on that a state of the waste liquid containing unit has changed from a first state in which the waste liquid containing unit is mounted on the mount unit to a second state in which the waste liquid containing unit is not mounted on the mount unit during the execution of recording processing in which the discharge unit discharges liquid to recording medium, the discharging unit not to perform the preliminary discharge operation, and
the control unit controls, based on that a state of the waste liquid containing unit has changed from the second state to the first state, the discharging unit to perform recovery processing including the preliminary discharge operation in order to recover the liquid discharge unit the liquid discharge apparatus to execute a first recovery operation for restoring the discharge unit.
