Abstract
An air pressurization pump is driven to apply pressurized air pressure to a main tank storing ink. The pressurized air causes the ink to be supplied from the main tank to a recording head arranged on a carriage. A CPU of an inkjet recording apparatus selectively sets a drive control mode and a power saving control mode. The drive control mode operates the air pressurization pump, and the power saving control mode consumes less power than the drive control mode. If the drive control mode ends, the CPU shifts to the power saving control mode when a predetermined time elapses after the drive control mode ends and stops operating the gas pressurization pump.
