LEV0 V/D OUT YMC
V1=***H
V1DA=***H
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]

V2DA=***H
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
V3DA=***H
V3=***H: Detected voltage value when the
LED current of YMC density sensor is 0[A].

Value after subtracting V1 from the CMY
sensor output [HEX]
If a value after subtracting is a negative
value, it is regarded as ‘0’.
SRAM
LEV0 V/D OUT K
V5=***H
Value after subtracting V1 from the K
sensor output [HEX]
If a value after subtracting is a negative
value, it is regarded as ‘0’.
