ment pattern (front, back) again.

* When [RESCAN] key is pressed, the SPF adjustment pat-

tern (front, back) is scanned again.

* When [RETRY] key is pressed, the adjustment value is not

saved in EEPROM and RAM and shifted to the top menu
screen.

* When [DATA] key is pressed, the data used in execution of

the adjustment are displayed.

screen.

 

1)

Open the lower door, and insert the white reference sheet
DSPF (PSHEP5668FCZZ). Close the lower door.

* When inserting the white reference sheet DSPF, insert it

straight along the rear edge frame so that the rear edge of
the white reference sheet DSPF comes at the root of the
actuator as shown in the mark {.

2)

Enter the simulation 63-2 mode.

3)

Select, [DSPF SHADING].

4)

When [EXECUTE] key is pressed, it is highlighted and shading
is started.
* When the operation is executed, the document is trans-

ported by about 25mm, and shading data are obtained dur-
ing transport.

* During execution, "SHADING EXECUTING..." is displayed.
* When [EXECUTE] key is pressed during execution, the

operation is interrupted.

* When shading is completed normally, [EXECUTE] key

returns to the normal display and "COMPLETED" is dis-
played.

* When [SYSTEM SETTINGS] key is pressed during other
