发明名称 INK-JET PRINT HEAD, INK-JET PRINTER AND METHOD FOR MAINTAINING INK-JET PRINT HEAD
摘要 PROBLEM TO BE SOLVED: To provide an ink-jet printer and an ink-jet print head capable of jetting ink stably at all times, and jet ink stably at all times. SOLUTION: An ink feed member 11 having an ink feed pipe 12 for feeding ink to a common reservoir 6 is provided with a plurality of gas-holding parts 13 holding a gas thereinside and communicating only with the common reservoir 6. A pressure because of air bubbles generated at a heat-generating element 4 discharges ink from a nozzle 3 and is transmitted to the common reservoir 6 thereby to change an internal pressure. Moreover, an opposite pressure change is brought about when the ink is refilled. These pressure changes are absorbed by an expansion/shrinkage of the gas in the gas-holding parts 13, so that the pressure change in the common reservoir 6 is suppressed. At the same time, blanking, a density irregularity, etc., are prevented.
