AR-SP10/RP10 ADJUSTMENTS

– 5 –

1) Open the SPF (RSPF) unit.

2) Execute Sim63-7.

3) The 7-seg display 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-seg display, if values are 93-229, and data are writ-

ten into the EEPROM.
(In this case, it means that the adjustment has been normally com-
pleted.)

•  It will display on 7-seg display, it values are 0-92 or 230-999, and data

are not written into the EEPROM.

•  It will display "--" on 7-seg display, it values is 1000 or larger, and data

are not written into the EEPROM.
(In these cases, the adjustment has not been normally completed.
Troubleshoot the cause and perform the adjustment again. )

Note: If the operation is executed with the SPF unit closed, an error

occurs. 
Also when the lens unit is replaced or when the optical axis of the
lens unit is shifted, an error occurs. 
In this case, it is necessary to perform the adjustment of the lens
unit described in “SPF white correction pixel position adjustment”
of the Service Manual of the machine. 

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 (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 indicator 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.
