AR-BC260 SETTING AND ADJUSTMENTS 8 - 21
(1) Note for the copy color balance/density adjustment
(Necessary conditions for execution of the copy color balance/density adjustment)
Before execution of the copy color balance/density adjustment, check that all the adjustments related to the copy color balance and density
have been completed properly.
The importance level is as shown below.
(Adjustment items which directly affect the copy color balance and density and must be checked or adjusted
before execution of the image quality adjustment)
1) Adjustment items: ADJ 2, ADJ 3, ADJ 4
The user color balance adjustment must be set to the center (default).
The set value of SIM 46-27 is set to the default.
The set value of the following simulation must be set to the default.
