P OFST Y/M/C/K
M/C/Y/K DMAX Density Value (reference only)
If the value of C , M , Y , or K DMAX is lower than 75, a fault may be assumed in the development of the color
in question.
If all values of C , M , Y , and K DMAX are lower than 75, a fault may be assumed in transfer or fixing.
If the value of C , M , Y , or K DMAX is 120 or higher and copies have fogging, a fault is assumed in ATR of the
color in question.

Use it to set data for correction of the target value for high
density areas in auto gradation correction mode (i.e., to
correct variation of CCD readings).
You must enter the value recorded on the service label
once again if you have initialized the RAM on the DC
controller PCB, since initialization returns it to the
standard value. Set to optimum value at time of
shipment.
