SET M1 Auto color balance adjustment target
setup
A. Outline
Auto color balance adjustment is performed with a certain color
balance (gamma) as a target. There are following two kinds of tar-
gets:
Only the service target among them allows optional setup of a color
balance (gamma) target.
1) Service target
This is provided to correct the shift in the reference color balance
(gamma) due to the machine fluctuations.
An optional color balance (gamma) target can be set according to
the user’s request.
In addition, the default target can be used as the service target.
Normally this is set to the standard color balance (gamma).
2) Factory target
This is the color balance (gamma) target which is set in the fac-
tory.
It is set to the standard color balance (gamma), and can be used
when the service target falls in an abnormal state by some
reasons.
It cannot be changed in the market.
When shipping from the factory, the service setup and the factory
setup are the same color balance (gamma) target.
This setup must be performed in the following cases:
•When the copy color balance and the density adjustment is
manually performed. (SIM 46-21)
•When a U2 trouble occurs.
•When the ICU main PWB is replaced.
•When the EEPROM on the ICU main PWB is replaced.
B. Setup procedure
(Procedure to set the standard color balance (gamma) or
an optional color balance (gamma) as the service target)
1) Two sheets of color patch image (adjustment pattern) are out-
putted in the copy color balance adjustment (manual adjustment)
(SIM 46-21). (ADJ M17/ADJ3)
At that time, when the color balance is shifted from the standard,
an adjustment is required. If not, there is no need to adjust.
If an optional color balance is required according to the user’s re-
quest, an adjustment is required.
2) Enter the SIM 63-7 mode.
3) Press the SETUP key.
4) Set the color patch image (adjustment pattern) paper printed in
the copy color balance adjustment (manual adjustment) (SIM 46-
21) (ADJ M17/ADJ3) on the original table.
Set the paper on the original table so that the darker density side
comes on the left side. Then place 5 sheets of white paper on the
color patch image (adjustment pattern).
5) Press the EXECUTE key.
The color patch image (adjustment pattern) is read.
6) Press the REPEAT key and set the second color patch image (ad-
justment pattern) on the original table.
7) Press the OK key.
The color balance (gamma) corresponding to the color patch
image (adjustment pattern) printed in the copy color balance ad-
justment (manual adjustment) (ADJ M17/ADJ3) is set as the ser-
vice target.
(Procedure to set the default (standard) color balance
(gamma) as the service target)
1) Enter the SIM 63-8 mode.
2) Press the EXECUTE key.
3) Press the YES key.
The service target becomes the same as the default (standard)
target.
NOTE: To reset to the original service target, SET M1 must be per-
formed.

ADJ M6 Image density sensor adjustment
ADJ 1 Image density sensor calibration
This adjustment must be performed in the following cases:
•When the image density sensor is replaced.
•When the transfer belt is replaced.
•When a U2 trouble occurs.
•When the PCU main PWB is replaced.
•When the EEPROM of the PCU main PWB is replaced.
The process control sensor gain adjustment means: The detection
level differs between machines due to variations in density detection
sensors and parts. To prevent against this, attach a seal of a certain
density on the belt to calibrate the sensor.
1) With the power OFF, open the right cover of the machine.
2) Pull out the transfer unit, and attach the adjustment sheet (UKOG-
0281FCZZ) to the belt.
(The attachment position is between the two separation pawls of
the fusing unit.)
3) Return the transfer unit. With the front cover open, turn on the
power.
4) Enter the SIM 44-13 mode.
5) Close the front cover.
6) Press the [EXECUTE] key.
The adjustment is automatically performed. When the adjustment
is completed, the [EXECUTE] key returns to the normal display.
7) Check that the SIM 44-13 values are within the specifications.
Check content Spec
PCLEDC (Sensor current in color calibration) 128 or below
DARK ID (Color image density sensor dark
voltage) 50 or below
P_PSI (Read value of calibration sheet) 102 ±5
P_CYI (Read value of calibration plate) 80 ±15
∗When an error message is displayed, clean the sensor and the
calibration plate, and adjust again.
∗If the above procedure cannot cancel the error, replace the
sensor and the calibration plate.
8) Turn off the power.
9) Pull out the transfer unit, and remove the adjustment sheet.
(The adjustment sheet is positioned in front of the cleaning blade
at the back of the unit as the transfer belt rotates.)
10) Return the transfer unit.
NOTE: If the motor drive power is turned on immediately after at-
taching the adjustment sheet to the transfer belt, the adjust-
ment sheet does not stop at the specified position and the
transfer belt keeps rotating.
As a result, the adjustment sheet may be damaged by the
transfer cleaning blade or the transfer cleaning blade may be
damaged by the adjustment sheet.
To prevent against this, be sure to observe the following.
1) Before entering the SIM 44-13 mode, open the right cover of
the machine to open the motor drive power line.
2) After completion of the adjustment, remove the adjustment
sheet from the transfer belt.
ADJ 2 Image density sensor sensing position
adjustment
This adjustment must be performed in the following cases:
•When the image density sensor is replaced.
•When the image density sensor section is replaced.
•When a U2 trouble occurs.
•When the PCU main PWB is replaced.
•When the EEPROM of the PCU main PWB is replaced.
1) Enter the SIM 44-23 mode.
2) Press the [EXECUTE] key. The adjustment is automatically per-
formed, and the average data is displayed.
When the operation is completed, the [EXECUTE] key is high-
lighted.
In case of an abnormal end, "ERROR" is displayed.

the [EXECUTE] key is pressed, printing is performed. Paper is
selected by the set item E.
3) Check the distortion of the printed image.
If the right-angle level of the traverse print line is 0.5mm or less for
the longitudinal print line of paper, there is no need to adjust.
4) If the image is distorted, loosen the red screw for the holder on the
chassis side, and adjust the LSU inclination with the black LSU
adjustment screw (set screw). (The LSU at the right end is black.)
After completion of the adjustment, fix the holder with the red
screw.
5) Enter the SIM 61-4 mode.
6) Select 11×17 paper and press the [EXECUTE] key. Paper is
selected by the set item B.

∗Use the paper tray at the bottom.
7) Check that the center shift between the Y/M/C print color patters is
within 0 ±1 step.
(Check the shift between the print patterns of the same color.
Even though there is some shift between different colors, there is
no problem.)
If the above condition is not satisfied, loosen the red screw for the
holder on the front side of the chassis, and adjust the LSU adjust-
ment screw (set screw) to adjust the LSU inclination.
After completion of the adjustment, fix the holder with the red
screw.
