ADJUSTMENTS

– 7 –

[Function]

The white correction start pixel position is automatically adjusted.

This adjustment is performed after the lens unit is replaced.

[Operation]

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.

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) 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>

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).

<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.

<Adjustment specifications>

1) Set a scale on the OC table as shown below.

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.

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 SPF white correction start pixel = Displayed pixel position - 34

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

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

Interruption is inhibited during execution.

Note: Since the printed paper is used as the test chart,
