    Abstract: PROBLEM TO BE SOLVED: To provide a method for ejecting a fluid to a receiving medium. SOLUTION: In the method, each swath and at least one other swath overlap each other, whereby an overlapping region is formed to these swaths. The fluid is ejected into a plurality of swaths, and fluid ejection data to pixels in the overlapping region is changed for swaths which define the overlapping region. Based on a pixel position in the overlapping region and at least one of control values made corresponding to pixels, a quantity of the fluid to be ejected for each pixel in the overlapping region is reduced for at least one of the overlapping swaths.

    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus to remove fibers and fine particles(debris) in the vicinity of the nozzles of a print head.
    SOLUTION: The apparatus includes a print head protector 50 surrounding the print head, and has a first slot 60, a second slot 62 surrounding the first slot 60 and wider than the first slot. A positive pressure air supply source is connected to a suction port 64 communicating with the first slot, and an outlet 66 communicating with the second slot is connected to a negative pressure source. Air from the suction port 64 flows externally as if to separate from the print head through the first slot 60, eliminates fibers and fine particles (debris) from paper approaching the print head. The debris is captured by a negative pressure near to the second slot 62 and is removed from a printer through the outlet 66.

    Abstract: PROBLEM TO BE SOLVED: To reduce contamination of the interior of a printer with fine matter separated from a support (a printing medium/paper) by using a low-cost means.
    SOLUTION: A baffle 70 for protecting a printing head 11 against fine matter coming from a printing medium 28 is built below the printing medium 28 and above the printing head 11 in an imaging device 10 which prints an image 26 on a drum 14 as an image transfer member using the printing head 11 and transfers the image 2 to the printing medium 28 inside a support feeder route passing above the drum 14. Further, contaminants separated from the printing medium 28 can be captured before the contaminants could reach the printing head 11 by orienting one side surface 72 of the baffle 70 serving as a tacky surface in the almost printing medium 28 direction. Besides, also a fine substance discharged from the drum 14 and the fine matter emitted from the drum 14 can be captured with the help of the drum 14 side surface of the baffle 14 serving as the tacky surface.

    Abstract: PROBLEM TO BE SOLVED: To reduce or eliminate regular error at the stitch part of a print. SOLUTION: The method for ejecting liquid to a medium comprises a step for moving an ejection head 10 having a first die ejecting liquid drops from a plurality of nozzles toward a medium 30, a step for ejecting a plurality of first liquid drops from a plurality of first nozzles in first ejection sequence during movement of the ejection head 10 toward the medium 30, and a step for ejecting a plurality of second liquid drops from any one of the plurality of first nozzles or a plurality of second nozzles in the second die of the ejection head 10 in second sequence different from the first sequence during movement of the ejection head 10 toward the medium 30, wherein one of the plurality of first liquid drops is adjacent to one of the plurality of second liquid drops and the stitch error between one of the first liquid drops and one of the second liquid drops is smaller than that when the second sequence is identical to the first sequence.
