Patent attributes
The present invention provides an ink jet recording apparatus having high printing quality, in which each nozzle array is driven using a plurality of driver ICs. Assuming that the input terminal nozzles Y (n-3), M (n-2), C (n-1), and Bkn of four actuators form a group n, a group 4 (G4) is formed from input terminals spanning four stages, i.e. Y1, M2, C3, Bk4, and from a group 5 onward, similar groups are formed repeatedly. Input terminals of different colors are connected in succession to a driver IC 26a according to a color cycle of C→Y→Bk→M. Meanwhile, input terminals of different colors are connected in succession to a driver IC 26b according to a color cycle of Bk→M→C→Y. In all of the nozzle arrays, the driver ICs which drive the nozzles are connected alternately in staggered form.
