<P>PROBLEM TO BE SOLVED: To highly accurately adjust a time point of jetting liquid from a nozzle of each nozzle array. <P>SOLUTION: A recording head 24 carries out relative movement to recording paper 200 in the x direction. A first nozzle train L1 containing a plurality of nozzles N arranged in the Y direction, and a second nozzle train L2 in which the plurality of nozzles N which are different from respective nozzles N of the first nozzle train L1 in positions of the Y direction are arranged in the Y direction, are formed with distance in x direction in parallel on a discharge surface 26 of a recording head 24. A driving signal generating part 64 generates a jet pulse PD 1 and a jet pulse PD 2. A diving circuit 32 injects an ink drop according to the jet pulse PD 1 from each nozzle N of a first nozzle train L1, and injects an ink drop according to the jet pulse PD 2 from each nozzle N of a second nozzle train L2. A control section 60 variably controls the time difference ΔT of the jet pulse PD 1 and the jet pulse PD 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
