摘要:
While the print head is reduced in size, the adverse effect of air flows produced by ink droplets as they are ejected from a small number of ejection opening arrays is minimized. A small number of first ejection opening arrays eject one of three primary colors—cyan, magenta and yellow—and a large number of second and third ejection opening arrays eject the remaining two primary colors. A fourth ejection opening array is disposed between the first ejection opening array and the second or third ejection opening array.
