3. Document size detection
1) Document size detection with the document set tray
When documents are set on the document set tray in the auto selec-
tion mode of paper/copy magnification ratio, the document size is
detected and paper and the copy magnification ratio are automatically
selected. When different sizes of documents are set, the max. size is
detected. The document width is detected by the document width sen-
sors (W1, W2, W3), and the document length is detected by the docu-
ment length sensors (L1, L2) to identify the document size. Judgement
of the document size is made in a certain timing after detecting the
document with the document set sensor (W0).

[6] ADJUSTMENTS
(1) RSPF sub scanning direction magnification
ratio adjustment
Note: When performing this adjustment, check that the CCD unit
is properly installed.
: When performing this adjustment, check that the OC mode
adjustment in copying is completed.
1) Place a scale on the document table as shown below, and make a
normal copy to make a test chart.
2) Set the test chart to the SPF and make a normal copy.
3) Compare the copy and the test chart.
If an adjustment is needed, perform the following procedures.
4) Execute SIM 8-5. The auto exposure lamp lights up.
5) After warming up, shading is performed. The current correction
value of the front surface sub scanning direction magnification ratio
is displayed on the display section in two digits.
6) Enter the set value, and press the START key.
The entered correction value is stored and a copy is made.
7) Change the duplex document mode to the simplex document
mode.
The MANUAL lamp lights up, and the current correction value of
the back surface sub scanning direction magnification ratio is dis-
played on the display section in two digits.
8) Enter the set value, and press the SATART key.
The entered correction value is stored and a copy is made.

(2) SPF document off center adjustment
Note: When performing this adjustment, check that the paper off-
center is properly adjusted.
1) Set the center position adjustment test chart (made by yourself) on
the RSPF.
<Adjustment specifications>
Draw a line in the center of paper. (In the scanning direction)
2) Make a normal copy from the manual feed tray, and compare the
copy and the test chart.
If an adjustment is required, perform the following procedures.
3) Execute SIM 50-16.
4) After warming up, shading is performed and the current off-center
adjustment value at each paper feed port is displayed on the dis-
play section in two digits.
5) Enter the set value and press the START key.
The entered correction value is started and a copy is made.
<Adjustment specifications>
Mode Specification SIM Set value
SIM
50-16 1 ~ 99
(3) SPF image lead edge position adjustment
1) Set a scale on the OC table as shown below.
2) Make a copy, and use the copied paper as the document and
make a copy from SPF again.
3) Check the copied paper. If an adjustment is required, perform the
following procedures.
4) Execute SIM 50-1.
5) Set the SPF lead edge position set value (Exposure display <MAN-
UAL> ON) so that the image similar to the adjusted image at the
OC image lead edge position described previously is printed.

Note: Since the printed paper is used as the test chart,
place the scale in parallel to both sides.
Note: Since the printed paper is used as the test chart,
place the scale in parallel to both sides.

(4) OC (SPF) open/close detection position
adjustment
1) Set a paper of A4 (8.5 x 11") on the OC table.
Check that the document size display on the operation panel is the
same as the set paper size.
2) Close the OC (SPF) so that your hand can be inserted, and re-
move the paper on the OC table.
The document size display does not change from 1).
3) Gradually open the OC (SPF) until the display on the operation
panel is changed. Measure the distance (A) in the figure below
when the display on the operation panel is changed (all document
size lamps are turned OFF).
<Specifications>
OC (SPF) open/close position A : 207 ~ 302mm
4) If the OC (SPF) open/close position A is not 207 ~ 302mm, adjust
the open/close sensor installing plate position shown in the figure
below.
