DMAX-STS Display of D-max control execution state
Lv.1 Details To display the D-max control execution state.
Use case - At periodical maintenance
- When a density failure occurs
- When an alarm or error occurs
Adj/set/operate method N/A (Display only)
Display/adj/set range 0 to 2
0: During execution
1: D-max control is not reflected due to failure in Patch Sensor output
value. (Only potential control is executed.)
2: Not executed (D-max control is OFF with DMAX-SW, DMAXS-
SW).
Appropriate target value 0
Default value 0

DMAX-N Dis of uncoated paper group dev contrast
Lv.1 Details To display the developing contrast Vcont determined by D-max
control for uncoated paper group.
This value is reflected to VCONT-N, but when the offset adjustment
is performed with DUPDWN-N, this value becomes different.
Use case When any error occurs on the maximum density or gradation, identify
the cause with this mode.
Adj/set/operate method N/A (Display only)

DMAX-N-L Uncoat ppr D-max ctrl Vcont, dens/tgt VL
Lv.2 Details To display the list of uncoated paper group's D-max control Vcont,
patch detection density and target density value at the latest.
This list consists of maximum Vcont during D-max control and patch
detection density (DENS) 1 to 5.
Use case When any error occurs on the maximum density or gradation, identify
the cause with this mode. Characteristics of V-D (Vcont and density)
can be grasped, and it is easily identified as high voltage error, laser
error, etc.
Adj/set/operate method N/A (Display only)
Display/adj/set range Vcont: 50 to 300
Patch detection density: 0 to 1023
Unit Vcont: V
Patch detection density: None
Appropriate target value Vcont: 150 to 250
Patch detection density: 500 to 1023

P-LED Patch sensor LED light correction result
Lv.2 Details Displaying the LED light intensity correction result (DA value) of the
patch sensor
The correction result is used for D-max control or D-half control.
Use case To separate the cause in the case of failure in maximum density or
gradation.
Adj/set/operate method N/A (display only)

P-B-AVE ETB background dtct result average VL
Lv.2 Details To display the average value of ETB background detection result by
Patch Sensor.
Detection result is used for D-max control and D-half control.
Use case When any error occurs on the maximum density or gradation, identify
the cause with this mode.
