摘要： A printer using a line-type ink jet recording head. The line-type head has pressure producing chambers formed by dividing nozzle openings extending in a recording paper width direction with vertical side walls and upper and lower ink flow paths which communicate with each other through the pressure producing chambers and extend in a horizontal direction. Each ink flow path has an inlet for replenishing ink and an outlet for discharging the ink. A plurality of pressure producing elements are provided for applying varied pressures to the pressure producing chambers for jetting ink droplets. A sealing member selectively seals the nozzle openings by abutting on the nozzle openings when the recording head has been evacuated to a predetermined position. An ink tank is connected to the inlets and the outlets through pipes, and an ink stream producing device is arranged in the pipes, for producing streams causing the ink to flow from the ink tank to the lower ink flow path and then to the upper ink flow path through the pressure producing chambers.

摘要： An ink jet printer in which hardened ink is readily and reliably removed from a nozzle plate. The ink jet printer includes a print head having a plural number of nozzle openings arrayed in the width direction of a recording paper, a head drive circuit for selectively outputting a first signal to cause a stream of ink droplets at a speed suitable for print and a second signal to cause ink to ooze through each nozzle opening, and a cleaning device with a rubbing function and which is usually positioned in a nonprinting region, but is movable in the longitudinal direction of the print head and with respect to a nozzle plate. In a cleaning mode, the cleaning device is operated while oozing ink from the nozzle openings. The hardened ink on the nozzle plate is dissolved by the oozing ink, and then removed therefrom through the rubbing and wiping operations of the cleaning device.

摘要： Disclosed is an ink-jet type recording device that includes drive signal generation circuit 84 for generating a trapezoidal drive signal in synchronization with a timing signal applied from an external device, switching transistors respectively for outputting a drive signal to piezoelectric vibrators in accordance with a printing signal applied from an external device, and control signal generation means for generating a pulse signal to turn on the switching transistors so that only a portion of the drive signal is output to any piezoelectric vibrators set in a non-printing condition in synchronization with a timing signal. This portion of the drive signal is applied to the piezoelectric vibrators belonging to those nozzle openings that should not jet out ink droplets in accordance with the pulse signal, so that menisci in the nozzle openings are merely vibrated slightly, respectively. As a result of this, ink existing in a pressure generation chamber and ink existing in the neighborhood of the nozzle openings are mixed together and thus solvent is supplemented to the ink existing in the neighborhood of the nozzle opening, thereby preventing formation of an ink film due to evaporation of the solvent. Also, even in the non-printing period, the piezoelectric vibrators respectively generate heat to thereby be able to prevent absorption of humidity from the peripheral environment.

摘要： The recording device of an ink jet type comprises a drive voltage generation circuit which, in synchronization with a timing signal given from outside, generates a first drive voltage having a trapezoidal wave form, a drive circuit which outputs a first drive voltage to a piezo-vibrator in accordance with a printing signal given from outside and also, in synchronization with the timing signal, outputs a second drive voltage, which is used to generate such a small pulse that cannot jet out ink drops from a nozzle opening, to the piezo-vibrator in which a non-printing condition has continued for one or more cycles, and control means which stops the application of the small pulse when the time of application of the small pulse after completion of a printing operation exceeds a given time. When the ink drops have not been jetted out for one or more cycles, the small pulse is applied to thereby vibrate menisci in the neighborhood of the nozzle opening, in order to prevent the nozzle opening from being clogged up without causing any ink mist. At the same time, at the time when the printing operation is interrupted and the application of the small pulse continues for a given time or longer, the application of the small pulse is stopped to thereby prevent an unnecessary increase in the viscosity of the ink in the nozzle opening which can occur due to the slight vibrations of the menisci.

摘要： With an ink jet recording head (8) comprising two common ink chambers (26) and (27) communicating with both sides of a pressure generation chamber (24) and ink supply ports (30) and (31) where ink flows into the common ink chambers (26) and (27) from the outside, one ink supply port (30) is connected to a subtank (10) and the other ink supply port (31) is connected to an ink cartridge (6). The subtank (10) is replenished with ink through the ink jet recording head (8). Since ink reversely flows into the ink cartridge (6) via the recording head (8) from the subtank (10) due to the head difference, ink in the recording head (8) can be forcibly circulated without complicating a flow passage configuration.
