MX-7040N  SIMULATION  6 – 126

 

63-2

Adjustment

Used to perform shading.

• DSPF-installed model

1)

Select [OC SHADING] key or [DSPF SHADING] key, and
press [EXECUTE] key.

Used to perform shading.

When the operation is completed, [EXECUTE] key returns to the
normal display.

 

63-3

Adjustment

Used to perform scanner (CCD) color bal-
ance and gamma auto adjustment.

Scanner

1)

Place the SIT chart (UKOG-0280FCZZ or UKOG-0280FCZ1)
on the reference position of the left rear frame side of the doc-
ument table. For the DSPF mode, put the SIT chart backside
up on the DSPF tray.

2)

Select [OC] key or [DSPF] key.

3)

Press [EXECUTE] key.

The scanner (CCD) color balance automatic adjustment is per-
formed.

When the operation is completed, [EXECUTE] key returns to the
normal display.

After completion of the operation, press [RESULT] key, and the
adjustment data are displayed. At that time, the target color of data
display can be selected with [R] [G] [B] key.
