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 selection
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 sensors (W1,
W2, W3), and the document length is detected by the document length
sensors (L1, L2) to identify the document size. Judgement of the docu-
ment size is made in a certain timing after detecting the document with
the document set sensor (W0).

[5] ADJUSTMENTS
1. Auto white correction pixel adjustment
1) Open the SPF (RSPF) unit.
2) Execute Sim63-7.
3) The 7-seg display indicates the order number of the pixel of the
white sheet for SPF (RSPF) exposure correction in the SPF (RSPF)
position.
position.
• It will display on 7-seg display, if values are 93-229, and data are writ-
ten into the EEPROM.
(In this case, it means that the adjustment has been normally com-
pleted.)
(In this case, it means that the adjustment has been normally com-
pleted.)
• It will display on 7-seg display, it values are 0-92 or 230-999, and data
are not written into the EEPROM.
• It will display "--" on 7-seg display, it values is 1000 or larger, and data
are not written into the EEPROM.
(In these cases, the adjustment has not been normally completed.
Troubleshoot the cause and perform the adjustment again. )
(In these cases, the adjustment has not been normally completed.
Troubleshoot the cause and perform the adjustment again. )
Note: If the operation is executed with the SPF unit closed, an error
occurs.
Also when the lens unit is replaced or when the optical axis of the
lens unit is shifted, an error occurs.
In this case, it is necessary to perform the adjustment of the lens
unit described in “SPF white correction pixel position adjustment”
of the Service Manual of the machine.
Also when the lens unit is replaced or when the optical axis of the
lens unit is shifted, an error occurs.
In this case, it is necessary to perform the adjustment of the lens
unit described in “SPF white correction pixel position adjustment”
of the Service Manual of the machine.
2. 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 (RSPF) 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 48-5.
5) The current correction value 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 TEXT mode.
The TEXT indicator lights up, and the current correction value of the
back surface sub scanning direction magnification ratio is displayed
on the display section in two digits.
back surface sub scanning direction magnification ratio is displayed
on the display section in two digits.
8) Enter the set value, and press the START key.
The entered correction value is stored and a copy is made.

3. 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 SPF (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.
If an adjustment is required, perform the following procedures.
3) Execute SIM 50-12.
4) The current off-center adjustment value is displayed on the display

4. 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 (RSPF) again.
3) Check the copied paper. If an adjustment is required, perform the
following procedures.
4) Execute SIM 50-6.
5) Set the SPF/RSPF lead edge position set value so that the image
