Details
V1=***H: Color density sensor output when
the LED current of the density sensor is
0[A]. [HEX]
V1DA=***:DA setting value of the LED
current of the density sensor at the color
density detection determined by the color
calibration of the density sensor. [HEX]
V2=***H: Black density sensor output when
the LED current of the density sensor is
0[A]. [HEX]
V1DA=***:DA setting value of the LED
current of the density sensor at the black
density detection determined by the black
calibration of the density sensor. [HEX]
V3=***H: Detected voltage value when the
LED current of YMC density sensor is 0[A].
[HEX]
V3DA=***: DAC setting value at YMC
multiple points [HEX]
Value after subtracting V1 from the CMY
sensor output [HEX]
If a value after subtracting is a negative
value, it is regarded as '0'.
Value after subtracting V1 from the K
sensor output [HEX]
If a value after subtracting is a negative
value, it is regarded as '0'.
