06
Copy lead edge position 
adjustment (SPF/RSPF) 
(SPF/RSPF EDGE) 
(Disabled when set to OC) 
(Executable only when the 
SPF/RSPF is installed.)
[Function]
Used to adjust the SPF copy lead edge.
When the adjustment value of the document scan position adjustment is increased by 1, the scan
start timing is advanced by 0.1mm. 
The print result is shifted to the opposite direction of the scan start position.
The adjustment mode can be changed by pressing [
/
] key. (Adjustment range: 1 – 99, Default:50)
When scanning a back surface of document, the mode must be changed to operate the RSPF by
pressing [2-SIDED COPY] key.
(*) : Support for the installation models. For non-installation models, skip.
When there is no document in the SPF, copy is inhibited.
When paper is discharged, the shifter is operated.
[Operation]
The operation is similar to test command 46-01.
10
Print center offset 
adjustment (PRT.OFF-
CENTER)
[Function]
Used to adjust the center offset position of copy images on copy paper and that in scanning docu-
ment.
When this test command is executed, the current set value is displayed.
Enter the adjustment value and press [START] key to save the setting and make a copy. (When the
set value is changed by 1, the center is shifted by 0.1mm.)
When the adjustment value is increased, the center is shifted to right. When decreased, the center is
shifted to left.
The modes can be selected by pressing [
/
] key.
When the set value is changed largely, the area outside the shading area may be scanned to cause
black streaks on the edges. When the RSPF is used, select the mode for use of the RSPF by [2-
SIDED COPY] key.
(*) : Support for the installation models. For non-installation models, skip.
In the 2nd print center offset adjustment, print is made forcibly as 1to2/Short Edge from OC regard-
less of duplex setting.
When paper is discharged, the shifter is operated.
[Operation]
The operation is similar to test command 46-01.

Memory reverse position 
adjustment in duplex copy 
(DPLX REVERSE) (Enabled 
when Duplex setting is ON 
with OC or SPF set) 
(Executable only when the 
RSPF is installed.)
[Function]
When this test command is executed, the current set correction value is displayed.
Enter the correction value and press [START] key to save the entered correction value. (Correction
value range; 1 – 99, Default: 50)
For S-D mode front surface print and print of even paged in D-S mode, reverse memory copy opera-
tion is performed from the rear edge of documents.
When, therefore, the print position adjustment of output images is required, adjust as follows:
In the reverse memory coping, when the document scan is made in the arrow direction, the output
image is printed from the rear edge of scan image,
When, therefore, the print lead edge is shifted, set the reference chart so that the reference position is
on the rear edge, and use this test command to adjust the set value so that the print lead edge is
matched.
Since printing is made from the image data most lately stored in memory to the lead edge data from
the print start position, the image lead edge adjustment is made by changing the end data position
stored in memory by the set value of this test command.
Since it is performed by changing the scan end position, the image position adjustment is made by
changing the scan end position and the end data stored in memory.
The initial value of duplex setting is "1to2/Long Edge" for the duplex model, or "2to1" for the simplex
model.
When paper is discharged, the shifter is operated.
[Operation]
The operation is similar to test command 46-01.
19
Duplex copy rear edge void 
adjustment (DPLX END 
EDGE) (Enabled when 
Duplex setting is ON) 
(Executable only when the 
RSPF is installed.)
[Function]
Used to adjust the rear edge void amount in duplex copy. 
When this test command is executed, the current set value is displayed in 2 digits. (Center value: 50.)
The adjustment modes can be selected by pressing [
/
] key. (Adjustment range; 1 – 99)
Enter the adjustment value and press [START] key to save the set value and make a copy. (The
paper information is cleared for every copy.)
When the set value is increased by 1, the void amount is increased by about 0.1mm.
The initial value for duplex setting is "1to2/Short Edge" for the OC/SPF setting, or "2to2" for the
RSPF setting.
When paper is discharged, the shifter is operated.
[Operation]
The operation is similar to test command 46-01.

Resist amount adjustment 
(RESIST ADJ.)
[Function]
Used to adjust the contact pressure of the main unit resist roller and the RSPF resist roller onto paper.
When this test command is executed, the current set value is displayed. 
The adjustment modes can be selected by pressing [
/
] key.
Enter the adjustment value with [10KEY] and press [START] key to save the set value and make a
copy.

SPF scan position automatic 
adjustment (SPF AUTO) 
(Disabled when set to OC) 
(Executable only when the 
SPF is installed.)
[Function]
Place a black chart so that it covers the SPF scan glass and the OC glass together, and close the OC
cover.
When this test command is executed, the current adjustment value is displayed as the initial display.
Default is 1. Adjustment range is 1 – 99. Adjustment unit 1 = about 0.127mm
If the values are kept as the default values, SPF scan is not performed properly. The front area of
the proper scan position may be scanned.
In case of AUTO, press [START] key, and the mirror unit scans from the home position to the SPF
scan position with the adjustment value displayed. The SPF glass cover edge position is calculated
from the difference between the SPFG glass cover edge and the OC side document glass CCD out-
put level. If the adjustment is normal, the adjusted value is displayed. If abnormal, the error LED lights
up with the current set value displayed. 
During the error LED is lighted, when [START] key is pressed again, execution is performed again.
[Operation]
The operation is similar to test command 46-01.  (In MANUAL)

[Function]
When [OK (ENTER)/START] key is pressed, HSYNC is performed and the polygon motor is rotated 
for 30sec. 
At that time, the COPY mode lamp is lighted for 100msec every time when HSYNC is detected.

Shading check (SHADING 
CHK)
[Function]
Used to display the detection level of white plate for shading.
When [OK (ENTER)/START] key is pressed, the mirror base unit moves to the white plate for shading
and the copy lamp is lighted.
When the light quantity is stabilized, revision is made for every second, and the level of one pixel at
the center of CCD which is not corrected is detected and the value is displayed in decimal values on
the LCD. (3 digits)
[Operation]

Black level automatic 
correction (BLACK LEVEL)
[Function]
Used to acquire the black level target value used for the black level adjustment of white balance.
When this test command is executed, the current correction value is displayed in 3 digits of 12bit
hexadecimal number.
Place the gray gradation chart (UKOG-0162FCZZ) used as the correction document so that the den-
sity 10 (black side) comes on the left side and that the chart is upside down at the center of the plate
left center.
When [OK (ENTER)/START] key is pressed, the mirror base unit scans the chart and calculates the
correction value.
After completion of correction, the corrected value is displayed on the LCD.
Default: 0
If the value is set to the default, operation is made with 0x60.
