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
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 document size is made in a certain timing after
detecting the document with the document set sensor (W0).

[Function]

The SPF white correction start pixel position is automatically adjusted.
This adjustment is performed after the lens unit is replaced.

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 8-1. The auto exposure lamp lights up.

[OK] key: Shifts to the execution menu.

Interruption is inhibited during execution.

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

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 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.

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.
