Abstract
An inkjet recording apparatus includes: exchangeable first and second ink cartridges; a recording head which jets ink to a recording medium; an intermediate tank which receives the ink from the ink cartridge and supplies the ink to the recording head; a detecting sensor which detects whether ink residual quantity of an ink cartridge is not more than predetermined quantity based on ink quantity in the intermediate tank; a switching section which, if the ink residual quantity is not more than the predetermined quantity, switches the ink cartridge for supplying the ink to the intermediate tank; a first detector which detects the reset of the first ink cartridge; a second detector which detects the reset of the second ink cartridge; and a controller which, if the first ink cartridge is reset, controls the switching section to switch the second ink cartridge to the first ink cartridge, for supplying the ink.
