The color balance adjustment (automatic adjustment) is used to
adjust the copy density of each of Cyan, Magenta, Yellow, and

When this adjustment is executed, the color balance adjustments
of all the copy modes are revised.
The color balance adjustment (automatic adjustment) is used to

2)
Auto color balance adjustment by the user (The user program
mode is used.) (The color balance target is the service target.)
The auto color balance adjustment by the user is provided to
reduce the number of service calls.
If the copy color balance is lost for some reason, the user can
use this color balance adjustment to recover the balance.
When, however, the machine has a fatal problem or when the
machine condition is greatly changed, this function does not
work effectively.
If the machine condition is dramatically changed, a fatal prob-
lem occurs, or the normal color targets cannot be obtained,
service must recalibrate the machine to specification.
To perform the adjustment, the above difference must be fully
understood.
