Claims

[Claims for Utility Model Registration] A plurality of ink jet heads arranged in the circumferential direction or axial direction of a rotating drum form dots in each circumferential scanning line to print images such as characters and figures. This is a recording position adjustment device for an inkjet printer, which is installed in a rotating drum scanning type inkjet printer and adjusts the recording position of the recording dots of the inkjet head, and is adapted to compensate for dot misalignment caused by the characteristics and position of each inkhead. a correction setting means for setting, a head driving means for separately controlling the timing of driving the ink heads for each color, a memory means for storing printing data, and a correction setting means for reading data from the memory means and setting the ink head by the correction setting means. and means for outputting data to the head driving means after shifting by the amount of correction, and the correction setting means sets correction setting data in the memory storage means based on input from a switch means for inputting data provided on an operation panel. ,
A recording position adjustment device for an inkjet printer, characterized in that the position is adjusted according to the set value.
