Abstract
Abstract Translated from Japanese (57)【要約】 【課題】 1パス記録モードにおける境界部での紙送り 誤差による白すじ発生と、マルチパス記録モードにおけ る境界部での白すじ及び黒すじの発生を防止し得るよう にする。 【解決手段】 インクを吐出するノズルを所定のノズル ピッチで配列した記録ヘッドと、記録ヘッドを所定の主 走査方向に沿って移動させるヘッド移動手段と、主走査 方向と交差する副走査方向に沿って所定の搬送量で記録 媒体を搬送する記録媒体搬送手段と、を備え、前記記録 ヘッドは、主走査記録に用いる所定数のノズル群の副走 査方向における長さが前記搬送量より長くなるよう、前 記所定のノズルピッチが長く設定される。 (57) [Problem] To prevent the occurrence of white streaks due to a paper feed error at the border in the one-pass printing mode and the occurrence of white streaks and black streaks at the border in the multi-pass printing mode. . SOLUTION: A recording head in which nozzles for ejecting ink are arranged at a predetermined nozzle pitch, a head moving means for moving the recording head along a predetermined main scanning direction, and a sub-scanning direction intersecting the main scanning direction Recording medium transport means for transporting a recording medium by a predetermined transport amount, wherein the printhead is configured such that the length in the sub-scanning direction of a predetermined number of nozzle groups used for main scanning printing is longer than the transport amount. The predetermined nozzle pitch is set long.
