AR-5127 SIMULATION 8 - 34
Operation/procedure
Keep the OC cover open for execution of this test command.
If the adjustment is normally completed, the adjusted value is dis-
played and written into the EEPROM.
If the adjustment is abnormal, "ERR" is displayed and the value is not
written into the EEPROM.
For that which is not adjusted because of abnormality, "---" is dis-
played.
Operation/procedure
Pressing the [OK] key performs the LSU test.
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.)
Operation/procedure
Pressing the [OK] key performs shading, and displays the result (cen-
ter pixel).
Operation/procedure
Set the SPF unit OPEN, and press the [OK] key.
[ ] indicates the order number of the pixel of the white sheet for SPF
exposure correction in the SPF 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.
The SPF white correction start pixel = Displayed pixel position - 34
If the simulation is executed with the SPF unit closed, an error is
resulted.

Purpose Adjustment
Function
(Purpose) Used to adjust the mirror unit SPF scan position
automatically.
For the SPF scan position auto adjustment, the mirror
unit is shifted to 11mm before the SPF glass cover
edge and is moved by self-boost, and images are
scanned in each step, and the position from the glass
cover edge is automatically detected.
[Adjustment value]
Default: 50 Setting range: 1 to 99
Adjustment unit 1 = about 0.127mm
