DENS-Y/M/C
Calculated value of the developer density (Y/M/C) (The difference to the target value is displayed
in %.)
Reference
The value is updated at the point when toner supply is performed after the main power switch was
turned on.
Correct value: -2.0 to 4.0%
1
REF-Y/M/C
Standard of the developer density on the developing cylinder (Y/M/C)
The value is updated at the point when toner supply is performed after the main power switch was
turned on.
Correct value: 464 to 560
1
SGNL-Y/M/C
Measurement value of the developer density (Y/M/C)
Measurement is performed every time when a job is entered.
Reference
The value is updated at the point when toner supply is performed after the main power switch was
turned on.
Correct value: 250 to 760
