When [START] key is pressed, the entered value is saved and the screen shifts to the sub code
input standby mode.

When the [START] key is pressed, HSYNC is performed and the polygon motor is rotated for 30 sec.
Every time when HSYNC is detected, the ZOOM indicator is lighted for 100msec.
The detection level of the white plate for shading is displayed.
(Operating procedure)
When the [START] key is pressed in the sub code input standby mode, the mirror base unit moves to
the white plate for shading and the copy lamp is lighted. Until the light quantity of the copy lamp is
stabilized, the sub code of "01" is displayed on the 7-seg display. When the light quantity of the copy
lamp is stabilized, it is revised every second, and the level of one pixel at the CCD center where no
correction is made is detected for 10 sec, and the detected level is displayed in hexadecimal on the
7-seg display. After completion of 10 sec detection, the machine goes into the sub code input
standby mode.
The SPF white correction start pixel position is automatically adjusted.
This is performed after replacement of the lens. Open the SPF unit and press the [START] key, and
the position (which pixel) of the white sheet for SPF exposure correction in the SPF position is
displayed on the 7-seg display.
If the value is 93 ~ 229, it is displayed on the 7-seg display and is written into the EEPROM.
If the value is 0 ~ 92 or 230 ~ 999, it is displayed on the 7-seg display but is not written into the
EEPROM.
If the value is 1000 or above, "-------" is displayed on the 7-seg display and is not written into the
EEPROM.
The pixel position -34 written into the EEPROM is considered as the SPF white correction start pixel
of the machine.
When shi simulation is executed with the SPF unit closed, an error will occur.
The optical system status is ignored and a self print is made. Also when a print command is sent
from the host, printing is performed.
(Operating procedure)
When this simulation is executed, warm-up is performed and the START indicator is lighted.
(However, the scanner is invalid and no initial operation is made.)
Enter the code number with the Numeric keys, and select a tray with the PAPER SELECT key and
press the [START] key. The selected tray start paper feed and printing is performed in the selected
pattern.
* Only the tray lamp and the online lamp are lighted, and no other lamps are lighted.

* When the destination is of AB series, print data are made in A3 size.
(Therefore, A3 paper is desirable.)
* When the destination is of inch series, print data are made in WLT size.
(Therefore, WLT paper is desirable.)
