COPIER > ADJUST > COLOR
Adjust the color balance for users. (Y/M/C/K color)
Adjustment method
- When you set a larger value, the image density becomes darker.
- When you set a smaller value, the image density becomes lighter.
Adjustment range: -8 to +8
[Factory setting value / Value after RAM clear: 0]
Adjust the density and color balance of a bright section. (Y/M/C/K color)
Adjustment method
- When you set a smaller value, fogging is reduced.
Adjustment range: -32 to +32
[Factory setting value / Value after RAM clear: 0]
Adjust the color balance of low-density area. (Y/M/C/K color)
Adjustment range: -8 to +8
[Factory setting value / Value after RAM clear: 0]
Use of this mode must be avoided as much as possible when the machine has been operating
normally.
Adjust the color balance of middle-density area. (Y/M/C/K color)
Adjustment range: -8 to +8
