Adjustment. 3 Color balance
The color balance is adjusted by adjusting the density of each color at the Full Color Mode. The adjustment is performed by selecting its density area from the following: low density, medium density and high density.
Adjustment Mode (05)
| Color | Text/ Photo | Text | Printed Image | Photo | Map | user custom | Item to be adjusted | Remarks |
|---|---|---|---|---|---|---|---|---|
| Yellow | 1779-0 | 1780-0 | 1781-0 | 1782-0 | 1783-0 | 7980-0 | Low density | The larger the value is, the darker the color to be adjusted becomes. Acceptable values: 0 to 255 (Default: 128) |
| 1779-1 | 1780-1 | 1781-1 | 1782-1 | 1783-1 | 7980-1 | Medium density | ||

Make a test copy and compare the image obtained with the current settings; if necessary, make adjustments according to the following procedure.
Notes:
- Be sure that this adjustment is made after performing "3.2.1 Automatic gamma adjustment".
- Changing the adjustment setting influences the adjacent density area slightly. E.g.: When the value of the medium density is larger, the adjacent areas in the low density and high density range will become slightly darker.
Procedure
- While pressing [0] and [5] simultaneously, turn the power ON.
- Key in the code of the mode to be adjusted (color and original mode) and press the [START] button.
- Select the density area to be adjusted with digital keys (0, 1 or 2), and press the [START] button.
0: Low density
1: Medium density
2: High density - Key in an adjustment value. (To correct the value once keyed in, press the [CLEAR] button.)
- Press the [ENTER] or [INTERRUPT] button to store the value in memory. → The equipment goes back to the ready state.
- For resetting the value, repeat step (2) to (5).
- Press the [FAX] button and then press the [START] button to make a test copy.
- If the desired image quality has not been attained, repeat step (2) to (7).
Range of the density area (low density, medium density, high density)
The color from 10 to 30 (low density), from 40 to 70 (medium density) and from 80 to 100 (high density) in No. TCC-1 chart can be used as a guide for the range of the density area influenced by the change of the adjustment value (low density, medium density, high density).
