Ink jet recording apparatus capable of increasing a monochrome print speed without causing ink supply shortage to an image

摘要: An ink jet recording apparatus capable of increasing a monochrome print speed without causing supply shortage to an image includes carriage, plurality heads mounted on the carriage and including first, second, successive for making dots in colors, respectively. The further head drive circuit selectively driving at variable frequency, speed, mode selecting multiple-head which is formed such way that dot first color least one second colors are positioned alternating sequence, control controlling generate adjust said frequency from level different equal or lower than exceeds level, when selected by circuit.
