DMAX-S-L
Vcont/dens/trgtVL in D-max cntrl: coatPP
Lv.2 Details
Displaying a list of Vcont, patch detection density, density target
value by the latest D-max control with coated paper group.
The list consists of the maximum Vcont, patch detection density
(DENS) 1 to 5 while D-max control is executed.
Use case
To separate the cause in the case of failure in maximum density or
gradation. It is available to figure out characteristic of V-D (Vcont and
density) and also easy to separate the cause such as failure in high
voltage or laser.
Adj/set/operate method N/A (display only)
Display/adjust/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
