Use it to indicate the concentration of the developer inside the developing machine.
DENS-Y/M/C/K
Indicates the measurement of the developer concentration.
Indicates the difference from the target value in %.
Optimum: -1.5% to 1.5%
DMAX-Y/M/C/K
Indicates the measurement of the density of solid areas.
Indicates the average of test pattern densities showing the degree of differ-
ence from the target value of the solid density read at time of auto gradation
correction in user mode.
Optimum: DMAX-Y: 188 to 245
DMAX-M: 207 to 265
DMAX-C: 227 to 283
DMAX-K: 226 to 284
VRATE-Y/M/C/K
Indicates the correction value of the contrast potential.
Indicates the degree of correction to be made to the contrast potential (in %)
as a result of executing auto gradation correction.
Optimum: 70% to 130%
INIT-SIG-Y/M/C/K
Indicates the density signal level of initial developer.
Indicates the initial developer concentration signal level at last printing
(concentration signal level is corrected to suit the environment and wear).
Optimum: 104 to 188
