machine can be used.
Set the pattern so that the light density side is on the left side.
Place 5 sheets of white paper on the color patch image
(adjustment pattern).
This procedure must not be executed when the copy color bal-

the same color balance as the factory color balance target)
This procedure must not be executed when the copy color balance
was adjusted with SIM 67-25 to a unique color balance requested
by the user and it was registered as the service color balance tar-
get with SIM 67-27.
When the factory color balance target is changed with SIM 67-26,
be sure to execute this procedure.

replaced.
* When the CCD unit is replaced.
* When the scanner (reading) section is disassembled.
* When the scanner (reading) unit is replaced.
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.
* The scanner control PWB has been replaced.
* The EEPROM on the scanner control PWB has been replaced.
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
(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-
matic copy color balance and density adjustment (SIM46-24) and
the automatic printer color balance and density adjustment (SIM67-
24). It saves considerable time when compared with performing
each of the auto copy/printer color balance and the density adjust-
ment individually.
The color balance adjustment (automatic adjustment) is used to
adjust the copy density of each of Cyan, Magenta, Yellow, and
Black automatically.
When this adjustment is executed, the color balance adjustments
of all the copy/printer modes are revised.
