2) Close the front cabinet.
3) Select a developing unit to be adjusted.
4) When [EXECUTE] key is press
ed, it is highlighted. The DV
roller rotates, and the toner density sensor detects toner den-
sity, and the output value is displayed.
The above operation is executed for 1.5 minutes, and the aver-
age value of the toner density  sensor detection level is set
(saved) as the reference toner density control value.
When the reference toner density control adjustment operation
is completed, [EXECUTE] key returns to normal from highlight.
This makes known about whether the adjustment operation is
completed or not.
The above operation is executed each of the lower speed
mode and the middle speed mode, and the reference toner
density control value is set for each of them.
If the operation is interrupted within 1.5 minutes, the adjust-
ment result is not reflected.
When [EXECUTE] key is pressed during the operation, the
operation is stopped and [EXECUTE] key returns to the normal
display.
If [EE-EU], [EE-EL], or [EE-EC] is displayed, setting of the ref-
erence toner density control value is not completed normally.
Troubleshoot the cause, remove the cause, and perform set-
ting again.
5) Cancel SIM 25-2.
6) Confirm that Install the toner cartridge is displayed, and install the toner cartridge by the following procedures.
7) Shake the toner cartridge horizontally several times.
8) Open the front cabinet, and insert each toner cartridge.
Be sure to install the color cartridges to their proper positions.
Avoid installation to a different color position. Do not forcibly insert the toner cartridge. 
Push it in until the cartridge is securely locked in place.
Developing units removed, be sure to remove the toner car-
tridges as well to prevent toner clogging.
Color toner cartridge positions
9) Close the front cabinet.
10) Confirm that Toner replenishment in progress is displayed, and wait until the display disappears. (It takes 30 sec - 6 min.)
This procedure is for checking  the toner supply operation from
the toner cartridge to the DV unit. The operation time differs
depending on the toner quantity in the toner cartridge, uneven
distribution of toner, and the internal state of the toner car-
tridge.
Do not perform operations which interrupt the above operation,
such as opening the front cover, entering the SIM mode, and
turning OFF/ON the power. If this precaution is ignored, Trou-
ble codes F2-40 - 43 or F2-64 - 67 or a over-toned condition
may occur.
When replacing developer, always r eplace all the three colors of
Yellow, Magenta, and Cyan. 
If only one color is replaced, color balance may be adversely
affected. Black developer can be replaced individually.
When developer is replaced, be sure to perform the color balance
adjustment.
When not replacing the developer, do not execute SIM25-2.

ADJ 3Image density sensor 
adjustment
Before executing this adjustment, check to confirm the following
items.
* Check to confirm that the colo r image density sensor (image reg-
istration sensor F) and the bl ack image density sensor (image
registration sensor R) are clean.
* Check to confirm that the image  density sensor calibration plate
is clean.
* Check to confirm that the tr ansfer belt is clean and free from
scratches.
 
3-A Image density sensor calibration
There are some parts variations in the image density sensor sec-
tion. Therefore, the absolute image  density detection level differs in
each machine. To correct this, calibration is executed.
This adjustment must be performed in the following cases:
* When the color image density sens or (image registration sensor
F) is replaced.
* When the image registration sensor unit is replace.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.
* The image density sensor and the standard reflection plate are cleaned.
Perform the color image density sensor (image registration sensor
F) calibration in one of the following methods.
Method 1
Color image density sensor (Image r egistration sensor F) calibra-
tion (SIM44-61)
When the image density sensor unit is replaced, perform the
adjustment by this procedure.
When the registration sensor unit is  replaced, the calibration value
is set manually with this method.  The calibration jig is not required.
Method 2
Color image density sensor (Image r egistration sensor F) calibra-
tion (SIM44-13)
When the color image density sens or (image registration sensor F)
is solely replaced, be sure to perfo rm the adjustment by this proce-
dure.
A calibration jig is required for this procedure.
The adjustment by this method must be performed in the following
cases:
• The SIM44-2 PCS_CL LED ADJ value is increased by aging and dirt of the image density sensor and the standard reflection plate.
• When the density of an output image is decreased and the differ- ence between the SIM44-2 PCS_CL LED ADJ value and the
SIM44-13 PCS_CL LED ADJ value is 30 or more, the image den-
sity sensor, the registration s ensor, and the standard reflection
plate may be dirtied.
In this case, clean the image dens ity sensor, the registration sen-
sor, and the standard reflection plate with dry cloth, and perform
calibration with SIM44-13 by using the calibration tool (UKOG-
0318FCZZ). a. Procedure by calibration (SIM44-61) of the color image 
density sensor (image registration sensor F)
1) Enter the SIM44-61 mode.
2) Select an adjustment item.
3) Enter the adjustment value with 10 key. As the adjustment value, enter  the value on the label attached
to the slot section of the toner cartridge (BK) of the sensor unit.
4) Press [OK] key.

b. Color image density sensor (Image registration sensor F) 
calibration (Method by SIM44-13)
1) Enter the SIM44-13 mode.
2) Open the front cover, and remove the waste toner box. Check to confirm that the belt tensi on of the primary transfer unit is
released (the separation lever of the primary transfer unit is as
shown in the figure).
If the belt tension is not released, turn the separation lever to
the state shown in the figure.
When the transfer belt tension of  the primary transfer unit is
released manually, turn on the power again after completion of
the work.
This procedure initializes the transfer roller to return it to the
home position.
3) Open the right paper transport unit, and remove the BK devel- oping unit, the BK OPC drum unit, and the primary transfer
unit. 4) Install the color image density sensor (image registration sen-
sor F) calibration jig (UKOG-0318FCZZ) to the sensor housing
section.
Engage the calibration jig with the projection of the sensor
housing, and slide it to the rear frame side.
5) Close the right paper transport unit, and manually turn ON the front door switch.
6) Press [EXECUTE] key. Color image density sensor (image registration sensor F) cali-
bration is automatically exec uted. When the operation is com-
pleted, the adjustment result is displayed and [EXECUTE] key
returns to the normal display.
If the adjustment is not completed normally, ERROR is dis-
played.
When an error occurs, the adjustment result is not revised.
In that case, check the following sections for any abnormality.
If any abnormality is found, repair and execute calibration
again.
* Color image density sensor (image registration sensor F)
* PCU PWB
* Image sensor calibration jig  (dirt, scratch, discoloration)
* Image density sensor standard  reflection plate (dirt, scratch, 
discoloration)
The message is displayed, indicating that the jig is removed
and the primary transfer unit is installed.
7) Remove the jig and install the BK developing unit, the BK OPC drum unit, and the primary transfer unit, and close the right
paper transport unit.
8) [EXECUTE] key is pressed again.
The image sensor calibration jig must be stored at lower tempera-
tures and low humidity without external lights.
When this adjustment is execut ed, perform the ADJ10B copy/
printer color balance adjustment with SIM46-74.

3-BImage density sensor adjustment
The image density sensor standard  reflection plate and the transfer
belt surface are used to make the sensitivity adjustment of the color
image density sensor (image regist ration sensor F) and the black
image density sensor (image registration sensor R).
This adjustment executes automatical ly at the outset of registration
adjustment operation and process control operation as well as
SIM44-2.
Normally, therefore, it is not r equired to perform this adjustment. It
is performed only when the sensor  is replaced or when the adjust-
ment result is checked.
1) Enter SIM44-2 mode.
2) Press [EXECUTE] key.
The sensitivity adjustments of the color image density sensor
(image registration sensor F)  and the black image density sen-
sor (image registration sensor R) are automatically performed.
After completion of the adjustment, the adjustment result is
displayed and [EXECUTE] key returns to the normal display.
If the adjustment is not completed normally, ERROR is dis-
played. When an error occurs, check the fo
llowing sections for any abnor-
mality.
• Color image density sensor  (image registration sensor F)
• Black image density sensor (i mage registration sensor R)
•PCU PWB
• Transfer belt (dirt, scratch)
• Transfer belt cleaner
• Image density sensor standard reflection plate (dirt, scratch, dis- coloration)
If any abnormality is found, repair and adjust again.
If an error occurs, the adjustment result is not revised.
