a. General
SIM46-74 is used to perform the automatic copy color balance and
density adjustment (SIM46-24) and the automatic printer color bal-
ance and density adjustment (SIM67-24) continuously.
Since it is desirable to perform the copy color balance adjustment
Since it is desirable to perform the copy color balance adjustment
(automatic adjustment) before the automatic printer color balance
and density adjustment, it is advisable to perform the adjustment in
this mode.
This mode is also advisable to effectively perform both of the auto-
This mode is also advisable to effectively perform both of the auto-
matic copy color balance and density adjustment (SIM46-24) and
the automatic printer color balance and density adjustment (SIM67-
24). It saves considerable time w hen compared with per forming
each of the auto copy/printer color balance and the density adjust-
ment individually.
The color balance adjustment (automatic adjustment) is used to
The color balance adjustment (automatic adjustment) is used to
adjust the co py density of each of Cyan, Magenta, Yellow, and
Black automatically.
