Title: Ink jet recorder
Inventor: KOJIMA MASATOMO
IPC: B41J2/175
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recorder in which a stabilized print quality can be guaranteed continuously by suppressing the quantity of ink to be discharged as much as possible while removing bubbles and solid matters surely. SOLUTION: An ink flow is formed sequentially through a manifold 40, a pressure chamber 41 and a nozzle 42 and the ink is discharged by increasing the pressure in an ink tank 22 by means of a pressure pump 32 at the time of purging. At the same time, an ink flow is formed sequentially through a first ink channel 24, a manifold 40 and a second ink channel 26 and the ink is collected in the ink tank 22. Since the resistance of a parallel channel of a plurality of pressure chambers 41 and nozzles 42 is set 1.5-3 times as high as that of the second ink channel 26, flow rate ink to be discharged and collected can be sustained at an appropriate level.
