Purpose Adjustment
Function Used to adjust the SPF/RSPF scan position of the
(Purpose) mirror unit automatically. For the SPF/RSPF scan
position automatic adjustment, the mirror unit is shifted
to 11mm before the SPF/RSPF glass cover edge, and
is operated automatically to scan images by the unit of
1 step, detecting the position up to the glass cover
automatically.
(Adjustment value)
Default: 50, Adjustment range: 1 - 99
Adjustment unit: 1 = about 0.12mm
Operation/Procedure
With the SPF/RSPF or the OC cover open, put a black background
chart on the OC glass (the SPF/RSPF glass surface is included for the
SPF/RSPF standard model), and press the [START] key.
If the adjustment is executed normally, the adjustment value is dis-
played and saved in the EEPROM. If an error occurs, "ERR" is dis-
played and the value is not saved in the EEPROM.
If the adjustment is not performed because of abnormality, "---" is dis-
played.
During execution of the adjustment, the operation cannot be inter-
rupted.

Operation/procedure
Press the [START] key, and the LSU test is performed.
Used to set the LSU to ON state and check that the sync signal
(HSYNC/) is outputted or not.
After operation for 30 sec, the result is displayed. (Interruption cannot
be made for 5 sec after starting the operation.)

This adjustment is performed after the lens unit is
replaced.
Section Scanner
Item Operation
Operation/procedure
Set the SPF/RSPF unit OPEN, and press the [START] key.
[ ] indicates the order number of the pixel of the white sheet for SPF/
RSPF exposure correction in the SPF/RSPF position.
If the adjustment is normally completed, "COMPLETE" is displayed
and data are written into the EEPROM.
In case of an abnormality, "ERROR" is displayed and no data is written
into the EEPROM.

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