There is provided a transmission device arranged in an electronic apparatus having a circuit board for input andor output and a conductive body. The position of the top of ejection orifices in a second ejection orifice row for ejecting color ink is spaced a length away from a first ejection orifice row for ejecting black ink. If so, the system uses the previously calculated solution as an initial input to the iterative process that produces the solution for the target cell. At least one of a concentration of the non-reactive zero gas and a concentration of the span gas is varied in the calibration mixture as a function of time.
