摘要：
An ink jet apparatus comprising an ink jet head (200); an ink container (201) for storing ink to be ejected out of the head; a carriage for mounting an exchangeable ink jet cartridge (202); a sucking device comprising a cap (101) to be placed in contact with the head when the ink is to be sucked out of the recording head of the cartridge and a pump (108) for generating a negative pressure, being connected to the cap; and a controller for controlling the sucking operation carried out by the sucking device; wherein the controller controls the cap to be held away from the head for a predetermined duration of time after carrying out the first sucking operation following the exchange of the ink container (201) by covering the head with the cap.
