Abstract
An ink jet apparatus includes a mounting section for exchangeably mounting a cartridge, devices for performing a recovery operation in order to improve the ink discharge condition of a recording head, and components for confirming the exchange history of the cartridge and a recording operation, these components having a confirmation result. A controller serves to control the recovery operation which is performed by the recovery means according to the confirmation result of the confirming elements. The controller makes the recovery devices operate when it is confirmed that a new cartridge is mounted on the mounting section.
