PROBLEM TO BE SOLVED: To provide a structure for filling a head with ink while pressurizing through a relatively simple structure. SOLUTION: A reinforcing plate is fixed to the film surface so that the film of an air damper is not damaged with a pressure when the head is filled with ink while pressurizing. Since inflation of the film is suppressed by the reinforcing plate, the pressure is transmitted efficiently and the head can be filled with ink easily. Since air in the head can be removed under pressurization, failure of ejection can be eliminated. COPYRIGHT: (C)2004,JPO |
