MX3501N  ADJUSTMENTS  7 – 9

6)

Load the SPF adjustment pattern on the DSPF.

7)

Press [EXECUTE] key, and scanning of the SPF adjustment
pattern selected in step 2) is started.

8)

When [ALL] is selected, load the SPF adjustment pattern on
the DSPF again, and perform the adjustment of the back sur-
face in the similar procedures.

9)

The adjustment result screen is displayed.
The value of this time is displayed, and the value of the last
time is displayed in the parenthesis (  ).

* When [REPRINT] button is pressed, the display returns to

the cassette select screen to allow self-print of the SPF
adjustment pattern (front, back) again.

* When [RESCAN] button is pressed, the SPF adjustment

pattern (front, back) is scanned again.

* When [RETRY] button is pressed, the adjustment value is

not saved in EEPROM and RAM and shifted to the top menu
screen.

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

of the adjustment are displayed.

10) When [OK] button is pressed, the adjustment value is saved in

EEPROM and RAM and the display is shifted to the end
screen.

1)

Fold 2 or 3 sheets of A3 paper (recommendable paper for
color copy) as shown below.

2)

Open the lower door, place the folded sheets of paper as
shown, and close the lower door.

3)

Enter the simulation 63-2 mode.

5)

When [EXECUTE] button is pressed, it is highlighted and
shading is started.
* During execution, "SHADING EXECUTING..." is displayed.
* When [EXECUTE] button is pressed during execution, the

operation is interrupted.

* When shading is completed normally, [EXECUTE] button

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

* When [SYSTEM SETTINGS] key is pressed during other

than printing, the display returns to the sub number entry
screen.

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)

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.

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.
