    • Even in the case where preliminary ejection is performed by a recording head having an array of pigment ink ejection outlets and an array of dye ink ejection outlets in which a length of the pigment ink ejection outlet array is longer than a length of the dye ink ejection outlet array, deposition of preliminarily ejected pigment ink at a preliminary ejection receiving portion is effectively prevented by providing an inclined surface at the preliminary ejection receiving portion so that ink from the dye ink ejection outlets is received at an upstream position of the inclined surface and ink from the pigment ink ejection outlets is received at a downstream position of the inclined surface in a direction of gravity.
    • 即使在通过具有颜料墨喷出口阵列的记录头和染料墨喷射出口阵列执行预喷射的情况下,颜料墨喷射出口阵列的长度长于染料墨喷射的长度 出口阵列,通过在预喷射接收部分处设置倾斜表面,使得来自染料墨喷射出口的墨水被接收在倾斜表面的上游位置并且墨水 颜料墨喷出口在倾斜方向的下游位置被接收。
