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

[6] ADJUSTMENTS

(1) Auto white correction pixel adjustment

[Function] The white correction start pixel position is automatically adjusted.

This adjustment is performed after the lens unit is replaced. [Operation]

Open the SPF (RSPF) unit and press the [OK] key. 7-segment indicates the order number of the pixel of the white sheet for SPF (RSPF) exposure correction in the SPF (RSPF) position.

It will display on 7-segment, if values are 93-299, and data are written into the EEPROM. It will display on 7-segment, it values are 0-92 or 230-999, and data are not written into the EEPROM.

It will display "--" on 7-segment, it values is 1000 or larger, and data are not written into the EEPROM..

[CA] key: Cancels the test command. [Interruption] key: Shifts to the sub code entry menu.

The SPF white correction start pixel = Displayed pixel position - 34

Interruption is inhibited during execution.

If the simulation is executed with the SPF unit closed, an error is resulted.

During execution,"EXEC" is highlighted

(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 be low, and make a normal copy to make a test chart.

(3) 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 SPF (RSPF).

Draw a line in the center of paper. (In the scanning direction)

2) Make a normal copy from the manual feed tray, and co mpare 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.

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 both sides.

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 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.

3) Check the copied paper. If an adjustment is required, perform the following procedures.

4) Execute SIM 50-6.
