Abstract: A method is provided which is intended to reduce a visibility of ink dots ejected onto a print medium during a preliminary ejection operation to produce a satisfactory printed image. Preliminary ejection data is compared with image data. When the preliminary ejection is necessarily performed on a pixel that has no image data, image data of a pixel close to the pixel being processed is searched. When image data exists, the image data is moved to a pixel that has preliminary ejection data. The preliminary ejection data is added to the image data one scan at a time to perform printing.

Abstract: In both a full-line and a serial printer, the amount of ink passing through nozzles of print heads is sometimes decreased below a normal value before and during actual printing. In the printer of the present invention, a preliminary ejecting operation is performed taking the opportunity in which the amount of ink passing through nozzles is decreased below a normal value. Then, the amount of ink passing through nozzles recovers to the normal value in ink ejection after the preliminary ejecting operation. Since only a small amount of ink is ejected through the nozzles during the preliminary ejection operation, dots formed on a print sheet are not noticeable. Further, it is unnecessary to move the print heads to a home position where an ejection recovering process is executed to remove ink having an increased viscosity.

Abstract: In an ink jet recording apparatus, it is detected whether or not an ejection has been performed at least one time while printing an image, with respect to each nozzle, within a predetermined period (preliminary on-paper ejection cycle corresponding to the checking area C1), and the nozzle which has performed the ejection at least one time is excluded from a target of preliminary ejection within a second predetermined period (preliminary on-paper ejection cycle corresponding to the checking area C2) subsequent to the above predetermined period. As for the nozzle not excluded from the preliminary ejection target, the preliminary ejection is performed at least one time onto paper (preliminary on-paper ejection area R2) as to each nozzle at a predetermined timing within the second predetermined period (preliminary on-paper ejection cycle corresponding to the checking area C2).

Abstract: In a print head having arrays of large nozzles and small nozzles with different ink ejection volumes that are connected to a common ink chamber, the preliminary ejection operation is performed 29,000 times first on only the large nozzles at an ejection frequency of 10 kHz to discharge viscous or mixed color ink from ink chambers. After the preliminary ejection operation of the large nozzles is finished, only the small nozzles are made to perform the preliminary ejection operation 2,000 times at an ejection frequency of 10 kHz. Reducing the number of preliminary ejections from the small nozzles in this manner can minimize the generation of stray mist. Further, by performing the preliminary ejection operation on the large nozzles first, it is possible to discharge enough viscous ink from the ink chamber.

Abstract: This invention allows images to be printed up to the edges of printing paper while preventing ink droplets from depositing on the platen. Ink droplets Ip are ejected from a print head 28 and printing is started when printing paper P is fed in the sub-scanning direction by upstream paper feed rollers 25a and 25b, and the front edge Pf reaches a position above a downstream slot 26r. Since printing is started when the front edge Pf of printing paper P has reached a position behind nozzle No. 1, images can be printed without forming blank spaces up to the front edge Pf of the printing paper P by causing the nozzles to eject ink droplets Ip irrespective of whether the nozzles are above the printing paper. When images are formed in the vicinity of the front edge Pf of printing paper P, the paper is repeatedly fed in small increments in the sub-scanning direction, and printing is carried out.
