The deflection amount of the ink rlV droplet 2 is detected based on the number, and the inkjet pump is operated based on the detection result.
The amount of deviation [t1] is corrected by adjusting the 11υ force, the weight of the ink liquid 71:'H2(7) belt', or the deflection voltage, thereby performing the Y9[constant printing operation.
