When replacing the DC Controller PCB, enter the ATR-INIT value
peculiar to each drum unit.
Use case - When identifying the cause at the occurrence of an image density
failure
- When replacing the DC Controller PCB
Display/adj/set range 0 to 255
Default value 0

DMAX-Y Adj D-max ctrl Y-color dens target VL
Lv.2 Details An image failure might occur because the density target value of the
D-max control becomes out of the setting table due to environment
change.
Adjust the offset of the Y-color density target value of D-max control.
The offset is reset when D-max control (full adjustment) is executed.
Use case When an image failure occurs due to environment change
Adj/set/operate method 1) Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
