Definitions

  • the ink-jet recording apparatus is equipped with a capping member for sealing the nozzle orifices of the recording head while the recording apparatus is in a non-printing mode, and a cleaning device for cleaning a nozzle plate, as required.
  • the cleaning operation is performed when a printing operation is resumed after the recording apparatus has remained in an idle mode for a long period of time or when the user actuates a cleaning switch for eliminating degradation in the quality of a recorded image.
  • the cleaning operation involves removal of ink droplets from the recording head by means of negative pressure applied through suction, and wiping of the surface of the recording head by means of a wiping blade formed from rubber or an elastic plate.
  • the recording head may be flushed within the capping member 10 or in the flushing region 13A constituted of the aperture formed in the paper guide member 8.
  • the recording head is flushed within the flushing region in order to prevent an overflow of ink, which would otherwise be caused when ink droplets are continuously ejected after the capping member 10 has already been filled with ink.
  • the related ink-jet recording apparatus is required to temporarily suspend a printing operation in order to flush the recording head, move the carriage to the capping member or the flushing region, return the carriage to the position where the printing operation was interrupted, after flushing of the recording head is completed, and resume the printing operation.
  • the related recording apparatus encounters technological problems; i.e., a deterioration in throughput associated with the flushing operation; and an increase in print time.
  • ink droplets ejected from the nozzle orifices of the recording head turn into mist as a result of air resistance and are suspended in air before arrival at the ink-absorbing member 14, thus staining the surroundings.
  • Ink droplets ejected from the nozzle orifices are electrically charged to a considerably degree.
  • the ink droplets are affected by the electrostatic charge developed in a drive section of the recording apparatus and are accelerated by an air flow induced by an exhaust fan disposed for preventing an increase in the internal temperature of the recording apparatus or an air flow resulting from movement of the carriage, thus staining as well the (external) area surrounding the recording apparatus.
  • a processing routine employed for the flushing operation comprises a step of deactivating a carriage motor within a predetermined flushing region and flushing a recording head, and a step of performing a print operation. As mentioned above, such a processing routine encounters a difficulty in increasing throughput.
  • an ink-jet recording apparatus comprising:
  • a distance between the porous sheet member and a surface on which the nozzle orifices are formed is set within a domain of 1 to 5 mm when the flushing operation is performed.
  • the periphery of the porous sheet member is enclosed by a case.
  • the ink ejected during flushing operation flows along the interior of the case and is absorbed by the ink absorbing member.
  • the lower end of the porous sheet member is partially notched such that an opening is defined by the notch and the inner face of the casing.
  • the porous sheet member is secured to the casing by a fixing member.
  • the fixing member is situated so as not to face the nozzle forming surface when the flushing operation is performed.
  • the present invention enables solving of a problem; i.e., staining of the interior or exterior of the ink-jet recording apparatus, which would otherwise be caused by the mist.
  • the first flushing is performed without stopping the carriage.
  • the flushing method is particularly desirable because it can prevent cumulative deposition of ink by changing the first and second positions.
  • the respective apertures are larger than a size of surface on which the nozzle orifices are formed.
  • the ink ejected from the recording head 5 for flushing purpose within the flushing region 13A or 13B is absorbed by the ink-absorbing member 14 housed in the waste-ink tank 15.
  • the ink adhering to the slant surface 20a becomes ink droplets as a result of the water-repellent layer formed on the slant surface 20a and falls to the ink-absorbing member 14. Accordingly, the ink-absorbing member 14 can be made compact.
  • the ink receiver unit 127 is attached to the recording apparatus such that an axial line 131 c of the second cylindrical body 131b is aligned substantially normal to the recording apparatus.
  • the present invention is not limited to such a specific type of recording apparatus. Needless to say, the same working-effect can be yielded even when the present invention is applied to another type of ink-jet recording apparatus.
  • black ink has a higher solid concentration than do yellow ink, cyan ink, and magenta ink, the black ink is susceptible to an increase in viscosity and is likely to solidify when solvent contained in the black ink evaporates.
  • the flushing controller 32 sends a control signal to the carriage position controller 37, which in turn sends a control signal, thus activating the pulse motor for moving the carriage 1.
  • the carriage 1 is moved to position B shown in Fig. 12 (called a second position), where the carriage 1 is stopped.
  • the carriage position controller 37 sends a control signal to the flushing controller 32, whereupon the nozzle orifices 5b, 5c, and 5d, which are assigned to yellow ink, cyan ink, and magenta ink, respectively, eject these colors of ink.
  • One end of the area over which the recording heads 112a and 112b mounted on the carriage 111 travel corresponds to a non-print region (the home position), where capping member 121 is disposed.
  • the flushing positions of recording heads may be determined by means similar to those mentioned previously, even in the case of a recording apparatus equipped with three or more recording heads.
