2.2 To Closely Match the Color Balance of the Original
Before the adjustment After the adjustment
The copy image looks yellowish, compared
with the original.
The color balance of the copy image is closely
matched with that of the original.
Explanation
Depending on the color balance of the original, the copy image sometimes looks different from the original.
Perform image quality control, automatic calibration, color adjustment (color balance adjustment or RGB
adjustment) and the color density adjustment, in order to match the color balance of the copy image with that of
the original.
Procedures
* You can start with any of the procedures. But it is recommended to perform the procedures in order, as listed
below. You can use one procedure in conjunction with another. But if this changes the image quality more
than required or loses the effectiveness of the adjustment, restore the settings made in the previously used
procedure to the original ones. Then use other procedures.
* Only the service technician must use procedures (1) and (5).
* Both the service technician and the user can use procedures (2) to (4).
*Procedure (3) "Hue adjustment" cannot be selected concurrently with procedure (4) "Color balance/RGB
adjustments." Performing either of the adjustments and then another adjustment clears what has been previously
adjusted. For example, using procedure (3) and then procedure (4) clears the adjusted hue using procedure (3).
