MX-7040N  SIMULATION  6 – 127

 

63-4

Adjustment/Setting/Operation data check

Used to display the SIT chart patch density.

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 patch of the SIT chart is scanned.

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

4)

Select a data display mode.

Select an target display color with [R] [G] [B] keys.

 

63-5

Adjustment/Setup

Used to perform the scanner (CCD) color
balance and gamma default setting.

1)

Press [EXECUTE] key, and press [YES] key

2)

The scanner (CCD) color balance and gamma are set to the
default.

 

63-6

Adjustment/Setting/Operation data check

Used to display the scan level and the den-
sity level of the copy color balance adjust-
ment patch.

1)

Set the color balance adjustment pattern sheet printed with
SIM46-21 on the document table.

2)

Press [EXECUTE] key.

The patch image of the adjustment pattern sheet is scanned.

Select a target color with [C] [M] [Y] [K] key.

 

63-7

Adjustment/Setup

Used to register the service target of the
copy mode auto color balance adjustment.

1)

Press [SETUP] key on the touch panel.

2)

Set the color balance adjustment pattern sheet printed with
SIM46-21 on the document table.

3)

Press [EXECUTE] key.

The patch image of the adjustment pattern sheet is scanned.

4)

Press [OK] key.

The service target of the copy mode automatic color balance
adjustment is registered according to the patch image of the
scanned adjustment pattern sheet.

The registered color balance and the density are displayed.

Select a target color with [C] [M] [Y] [K] key.

NOTE: This simulation is executed only when the copy color bal-

ance is manually adjusted.

 

63-8

Adjustment/Setup

Used to set the default of the service target
of the copy mode auto color balance adjust-
ment.

1)

Press [EXECUTE] key.

2)

Press [YES] key.

The service target of the copy mode automatic color balance
adjustment is set to the default.

The service color balance target and the color balance target
for the user color balance adjustment are set to the same color
balance as the factory color balance target.

 

63-11

Adjustment/Setup

Used to set the target color balance of the
copy mode auto color balance adjustment.

1)

Select the target color balance with the touch panel.

color 
balance

DEF1

The engine color balance adjustment target 
in the automatic color balance operation is 
slightly shifted to Magenta. When this target 
is selected, the color balance is converted 
into natural gray color balance by the color 
table in an actual copy mode and print is 
made.

DEF 1

DEF2

The engine color balance adjustment target 
in the automatic color balance operation is 
slightly shifted to natural gray color balance. 
When this target is selected, the color 
balance is slightly shifted to Cyan by the 
color table in an actual copy mode and print 
is made.

DEF3

The engine color balance adjustment target 
in the automatic color balance operation is 
slightly shifted to Cyan. When this target is 
selected, the color balance is converted into 
the color balance with enhanced Cyan by 
the color table in an actual copy mode and 
print is made.
