6)
Set the color patch image (adjustment pattern) printed in the
procedure 5) on the document table.
Set the color patch image (adjustment pattern) printed in the
procedure 2) on the document table. Place the color patch
image so that the fine lines are on the left side. At that time,
place 5 sheets of white paper on the printed color patch image
(adjustment pattern).
7)
Select [FACTORY] target, and press [EXECUTE] key.
When the color balance is customized with the manual color
balance adjustment (SIM 67-25) according to the user's
request and the color balance is registered as the service tar-
get with SIM 67-27, if the color balance is adjusted to that color
balance, select the [SERVICE] target.
The printer color balance adjustment (step 1) is automatically
performed and the color balance check patch image is printed

9) Wait until [EXECUTE] key is displayed. When it is displayed,
press it.
The halftone image correction is performed.
10) When "COMPLETED THIS PROCEDURE" is displayed, the
adjustment operation is completed.  Cancel the simulation.
11) Check the copy color balance and density.
(Refer to the item of the copy color balance and density
check.)
When satisfactory color balance and density are not obtained
from the automatic adjustment by selecting the factory target in
procedure 4), change the factory color balance target with SIM
63-11 and repeat the procedures from 1).
If a satisfactory result is not obtained with the above proce-
dure, perform the manual color balance adjustment.
Also when the service target is selected in procedure 4) to exe-
cute the automatic adjustment and a satisfactory result is not
obtained, perform the manual color balance adjustment.
12) Check the printer color balance and density.
(Refer to the item of the printer color balance and density
check.)
When satisfactory color balance and density are not obtained
from the automatic adjustment by selecting the factory target in
procedure 7), change the factory color balance target with SIM
67-26 and repeat the procedures from 1).  If a satisfactory
result is not obtained with the above procedure, perform the
manual color balance adjustment.  Also when the service tar-
get is selected in procedure 7) to execute the automatic adjust-
ment and a satisfactory result is not obtained, perform the
manual color balance adjustment.
If the color balance or density is not in the satisfactory level
even after execution of the automatic and manual adjustments,
there may be another cause.
Troubleshoot the cause, repair or perform necessary works,
and repeat the adjustment from the beginning.

Copy quality adjustment (Basic adjustment)
This adjustment must be performed in the following cases:
• When a consumable part (developer, OPC drum, transfer belt) is
replaced.
• The CCD unit has been replaced.
• When the scanner (reading) section is disassembled.
• When the scanner (reading) unit is replaced.
• U2 trouble has occurred.
• When the SCN-MFP control PWB is replaced.
• When the EEPROM on the SCN-MFP control PWB is replaced.

Copy color balance and density adjustment 
(Automatic adjustment)
a. General
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 modes are revised.
There are following two modes in the auto color balance adjust-
ment.
1)
Auto color balance adjustment by the serviceman (SIM 46-24
is used.)
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.
