    摘要： An ink jet printer includes a distance adjust mechanism for adjusting in two steps a distance between a liquid nozzle-formed face of a print unit and the recording surface, and a unit having first and second cleaning members with different free end positions, lengths and/or thicknesses are arranged movable relative to the face and adapted to wipe a substance adhering to the face off of the face with a predetermined engagement condition. The substance is wiped off of the face by the first and second cleaning members having different engagement conditions when the face is a first distance from a recording surface, and is wiped off with the engagement condition of a wipe portion of the first cleaning member virtually equal to the engagement condition of a wipe portion of the second cleaning member associated with the first distance when the face is a second distance from the medium. Further, a height difference between the cleaning members is set almost equal to the distance the face is moved by the distance adjust mechanism.

    摘要： A printing method capable of printing a high-quality image at a high speed and low cost and a corresponding printing apparatus are disclosed. In this printing apparatus, a shading-corrected mask pattern for multipass printing control in consideration of the characteristics of each printing element of a printhead is generated. The size of the mask pattern in the conveyance direction of the printing medium is set to be an integer multiple of the conveyance amount of the printing medium per scanning of the printhead. Image data masked using the mask pattern is transferred to the printhead and printed. Alternatively, the conveyance-direction size of the mask pattern for masking print data in accordance with each pass printing of multipass printing is set to be equivalent to the number of nozzles of an ink-jet printhead having a plurality of nozzles arrayed in the conveyance direction of the printing medium, and the mask pattern is dividedly used for each pass printing. Any error of the position of a dot printed on the printing medium by an ink droplet discharged from each nozzle is detected in units of nozzles. Printing may be performed using a mask pattern generated such that a printing element with a small error is frequently used in accordance with the detection result, or performed such that the positions of print data are exchanged.

    摘要： By performing printing by a reduced number of main scanning times and by a bind pitch of a period which is imperceptible to human vision, a printing apparatus and a printing method for forming an image of visually imperceptible banding artifacts is provided. For this purpose, in a printing apparatus wherein a printing head is scanned for a plurality of times in a main scanning direction and at each scanning the printing head is divided into a plurality of blocks and printing is made to a region corresponding to each of the blocks by multi-scanning printing, the region is formed by printing one divided region in each of the plurality of scans in a transporting direction.
