2) Enter the SIM 63-3 mode and press [EXECUTE] key.
The automatic operation is started. During the adjustment,
[EXECUTE] is highlighted. After completion of the adjustment,
[EXECUTE] returns to the normal display.
NOTE: Since the SIT chart (UKOG-0280FCZZ or UKOG-0280FC
Z1) is easily discolored by sunlight (especially ultraviolet
rays) and humidity and temperature, put it in a bag (such
as a dark file) and store in a dark place of low temperature
and low humidity.
20-A (2)
CCD gamma adjustment (CCD calibration)
(DSPF mode)
This adjustment is required in the following cases:
* When the CCD unit is replaced.
* When a U2 trouble occurs.
* When the scanner control PWB is replaced.
* When the EEPROM on the scanner control PWB is replaced.
(1) Note before adjustment
1) Check to insure that there is no dirt or dust on the SPF scan-
ning glass, the mirror, and the lens surface. (If there is, clean it
with alcohol.)
2) Check to confirm that the patches in BK1 and BK2 arrays of
the SIT chart (UKOG-0280FCZZ or UKOG-0280FCZ1) are
free from dirt and scratches.
If they are dirty, clean them.
If they are scratched or streaked, replace with new one.
NOTE:
Since the SIT chart (UKOG-0280FCZZ) is easily discolored by
sunlight (especially ultraviolet rays) and humidity and tempera-
ture, put it in a bag such as a clear file) and store in a dark
place of low temperature and low humidity.
(2) Adjustment procedures
1) Set the SIT chart (UKOG-0280FCZZ or UKOG-0280FCZ1)
face-down in the DSPF paper feed tray.
If the SIT chart is not available, execute SIM 63-5 to set the
CCD gamma to the default. In this case, however, the adjust-
ment accuracy is lower when compared with the adjustment
method using the SIT chart.
NOTE: UKOG-0280FCZZ is equivalent to UKOG-0280FCZ1.
2) Enter the SIM 63-03 mode.
3) When a color button is selected, the adjustment value of the
selected color is displayed.
* When [B] (Blue), [G] (Green), or [R] (Red) button is selected,
the selected button is highlighted and the adjustment value
of the selected color is displayed.
* Only one color button can be selected, and the selected but-
ton is highlighted. In the initial state, [B] is selected.
* If there is a page over [↑], an active display is shown and the
page moves up. If there is no page upward, the display
grays out and the operation is invalid.
If there is a page under [↓], an active display is shown and
the page moves down. If there is no page downward, the
display grays out and the operation is invalid.
