QAR-SP6N (SPF) 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. Judgment of the docu-
ment size is made in a certain timing after detecting the document with
the document set sensor (W0).

– 7 –
[6] ADJUSTMENTS
(1) Auto white correction pixel adjustment
1) Open the SPF fully.
2) Execute SIM63-7.
3) When the process is completed, "COMPLETE" is displayed on the
LCD.
4) When "EROR" is displayed, perform the following procedures.
QWhen the display is "- - -"
• Is the SPF closed?
• Is the lamp lighted? (If the lamp is not lighted, check the connector.)
• Is the CCD harness properly connected to the MCU connector?
QWhen the display is 281 or above:
1) Remove the table glass.
2) Remove the dark box.
3) Slide the lens unit to the front side and install it. Execute the simulation.
QWhen the display is 143 or below:
1) Remove the table glass.
2) Remove the dark box.
3) Slide the lens unit to the rear side and install it. Execute the simulation.
*When the lens unit is moved, execute the OC main scanning direction
magnification ratio adjustment SIM48-1 and SIM48-3, and execute
the SPF document off-center adjustment.
*This adjustment is basically completed with SIM63-7.
(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 OC 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) After completion of warming up, shading is performed.
6) Check to confirm that "RSPF(SIDE1)" mode is selected with the
cross cursor.
7) Enter the set value, and press the START key.
The entered correction value is stored and a copy is made.

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 50-12.
4) The current off-center adjustment value is displayed on the display
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>
(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
similar to the adjusted image at the OC image lead edge position
described previously is printed.
