Insert the power plug of the copier to the outlet and turn on
the main switch of the copier.
8. Adjust the RSPF white correction pixel.
• Open the RSPF and execute SIM 63-7 to adjust the RSPF auto white
correction pixel.
1) Open the SPF unit and press the START key.
2) Shading position adjustment is performed. (Cannot interrupt)
If the simulation is executed with the SPF unit closed,an error is resulted.
3) [ ] indicates the order number of the pixel of the white sheet for SPF
exposure correction in the SPF position.
When the adjustment is completed normally, “COMPLETE” is dis-
played, and data are written into the EEPROM.
When the adjustment is completed abnormally, “ERROR” is dis-
played and data are not written into the EEPROM.
*The SPF white correction start pixel = Displayed pixel position -34.
9. Adjust the document guide width (Sim53-6)
Caution: If this adjustment is not performed, the document size display
remains special.
1) With the document guide opened to the full, set A/3 (A/4) (WLT (LT)
in the inch system) paper and adjust the guide.
Press the start key.
2) Set to A4R (LTR) size, adjust the guide and press the start key.
3) Fold the A/4 (LTR) paper in half, set to the A5R (Invoice R) size,
adjust the guide and press the start key.
4) Adjust the guide to the minimum width and press the start key.
5) Make sure the indicator reads 60 before pressing the start key.
6) Make sure the indicator reads 40 before pressing the start key.
7) Make sure the document size is correctly shown in Sim2-2.
10. Check the copy magnification ratio.
• Set an original on the document glass and copy it.
Then, set an original in the document feeder tray and copy it.
• If the magnification ratio of the copy from the RSPF is different from
that of the copy from the document glass, carry out adjustment refer-
ring to the service manual.
11. Check the center displacement.
• Set an original on the document glass and copy it.
Then, set an original in the document feeder tray and copy it.
• If the center of the copy image from the RSPF is different from that of
the copy image from the document glass, carry out adjustment refer-
ring to the service manual.
12. Check the top end position.
• Set an original on the document glass and copy it.
Then, set an original in the document feeder tray and copy it.
• If the top end position of the copy image from the RSPF is different
from that of the copy image from the document glass, carry out
adjustment referring to the service manual.
13. Check the open/close detection position.
• If the open/close detection position measured with the open/close
detection position adjustment method described in the service man-
ual does not conform to the specifications, carry out adjustment refer-
ring to the service manual.
Installation of RSPF is now complete.

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 (SWD),
and the document length is detected by the document length sensors
(L1, L2) to identify the document size. Judgment of the document size is
made in a certain timing after detecting the document with the docu-
ment set sensor (EMPS).

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 RSPF and make a normal copy.
3) Compare the copy and the test chart.
If an adjustment is needed, perform the following procedures.

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 lamp 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.
8) Enter the set value, and press the START key.
The entered correction value is stored and a copy is made.
<Adjustment specifications>
(3) RSPF document off center adjustment
Note: When performing this adjustment, check that the paper off-cen-
ter 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 50-12.
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.

(4) RSPF 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 RSPF again.
3) Check the copied paper. If an adjustment is required, perform the
following procedures.
4) Execute SIM 50-6.
5) Set the 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.
<Adjustment specifications>
(5) SPF scan position automatic adjustment
The SPF scan position is automatically adjusted.
1) With the SPF or the OC cover open, place a black background chart
on the OC glass. (The SPF standard model includes the SPF glass
surface.)
*Use a black chart UKOG-0011QSZZ, or make a chart as shown
below and use it.
2) Enter SIM 53-08, and press the COPY button.
Caution:
• After completion of the SPF scan position automatic adjustment,
perform the SPF lead edge adjustment (both surfaces).
• Place no other things than the black chart on the glass.
• Since SPF scan is made around the center in the main scanning
direction, take care not to allow external lights to enter the section.
3) Check that the lead edge is not shifted. (Both surfaces)
(If the precedent lead edge adjustment was complete, the lead
edge follows automatically after changing the scan position.)

Use a cutting sheet No. 791 (Black) or an equivalent for

Reason: To protect against erroneous detection caused by dis-
turbed lights of fluorescent lamps, etc.
Outline of SIM: The optical unit is moved to recognize the boundary
between the OS glass and the SPF glass. The SPF
scan position is automatically adjusted with the
boundary position as the reference.
Note: Since the printed paper is used as the test chart, place the
scale in parallel to the front edge of the copy glass.
Place no other
things than the black
chart on the glass.
For the SPF standard
machine, check that the SPF
glass is covered completely
by the black chart.
