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 detect ed
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 document set sensor (EMPS).

(2) RSPF 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 mak e a
normal copy to make a test chart.
Open the SPF unit and press the [START]
key. [ ] 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 displayed,
and data are written into the EEPROM.
The SPF white correction start pixel
= Displayed pixel position - 34
If the simulation is executed with the
SPF unit closed, an error is resulted.
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.

1) Set the center position adjustment test chart (made by yourself) on
the RSPF.

Draw a line in the center of paper. (In the scanning direction)
2) Make a normal copy from the manual feed tray, and compare t he

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) RSPF image lead edge position adjustment
1) Set a scale on the OC table as shown below.
Note: Since the printed paper is used as the test chart, place the
scale in parallel to the front edge of the copy glass.
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

things than the black
chart on the glass.
machine, check that the SPF
glass is covered completely
by the black chart.
(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.
Chart size: 310 x 470
Use a cutting sheet No. 791 (Black) or an equivalent for
making a chart.
Reason: To protect against erroneous detection caused by dis-
turbed lights of fluorescent lamps, etc.
2) Enter SIM 53-08, and press the COPY button.
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.
Caution:
• A fter 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.
How to place the black chart
Cover this area.
• Since SPF scan is made around the center in the main scanning
direction, take care not to allow external lights to enter the section.
