Abstract
A recording apparatus includes a recording head having discharge ports for discharging a liquid, a cap configured to cap the discharge ports, a switching unit configured to switch between a communication state where an inside of the cap communicates with the atmosphere and a non-communication state where the inside of the cap does not communicate with the atmosphere, and a depressurization unit configured to depressurize the inside of the cap. After driving of the depressurization unit is started while the cap is at a capping position for capping the discharge ports and is in the non-communication state, the switching unit switches the cap to the communication state and then the driving of the depressurization unit is stopped. Idle suction is performed by driving the depressurization unit while the cap is at the capping position and is in the communication state.
