摘要： An air removal unit (36) is disposed in a conduit (35) leading from an ink reservoir (34) to an ink ejection head (37). The amount of entrained air in the ink in the head (37) is sensed, and a heater (39) connected to the removal unit (36) is energized to heat the ink and boost the air removal efficiency when the amount of entrained air is above a certain value. The air removal unit (36) includes a container (47) and partitions (51), (52) provided in the container (47) to define chambers. The ink flows upwardly and downwardly through the chambers and the entrained air rises into a collection chamber (54) from which it is vented to the atmosphere.

摘要： In the pressure, on-demand type ink-jet printers or the like, the driving voltages applied to respective electrostrictive means of print head or nozzle units are shifted in time so that constructive interferences of sound waves produced by the pressure waves which in turn are generated bu respective print head or nozzle units may be avoided, whereby the over-all intensity of sound waves and consequently noise may be remarkably suppressed.

摘要： An ink receptacle for an on-demand type ink jet printer in which an ink reservoir for storing ink which is to be ejected from an ink jet head is mounted on a carriage. A relatively thick flat housing which is made of non-flexible resin and open at one surface and a single flexible film are bonded together, the film covering the open side of the housing. The housing and the film cooperate to define a relatively large first ink chamber having an opening which is open to the outside and a relatively small second ink chamber also having an opening which is open to the outside. That part of the film which covers the first chamber is deformable to vary the volume of the first chamber corresponding to an amount of ink remaining in the chamber.

摘要： An ink jet printing apparatus capable of removing bubbles introduced into ink which is routed from an ink supply cartridge to a plurality of nozzles. A head holder adapted to support a head, which has the nozzles, is formed with an ink supply path for delivering ink from the ink supply cartridge to the nozzles. The ink supply path branches into an upwardly extending passageway and a downwardly extending passageway. The ink is supplied to the nozzles by way of the downward passageway. A check valve is positioned in the upward passageway for trapping bubbles entrained by the ink. The bubbles trapped by the check valve are discharged by a suction pump.

摘要： An ink clog is automatically sensed in an ink ejection nozzle (14). The clog is cleared by moving a cap (28) into covering engagement with the nozzle orifice, causing solvent to flow through the nozzle (14) from the cap (28) to dissolve the clogged ink and subsequently causing air to flow through the cap (28) and nozzle (14) to purge solvent therefrom.

摘要： In one embodiment of the present invention an ink manifold is divided into a first ink chamber communicated with an ink drop issuing nozzle and a second ink chamber communicated with an ink source and the first ink chamber through a narrow passage. First and second piezoelectric elements are mounted in opposed relationship with the first and second ink chambers, respectively. The second piezoelectric element is normally applied with such a second driving voltage that the ink will not issue through the nozzle. The frequency of a first driving voltage applied to the first piezoelectric element is twice as high as that of the second driving voltage, and the first driving voltage is selectively applied in synchronism with the second driving voltage only during the positive going half cycle thereof so that an ink drop may be issued through the nozzle during the positive going half cycle of the first driving voltage. In another embodiment of the present invention a plurality of ink drop generating cells substantially similar in construction to the ink drop generator described above are assembled to provide an ink drop generator having an array of nozzle matrix.
