MX-7500N  SIMULATION  6 – 125

 

61-4

Adjustment

Used to print the print image skew adjust-

ment pattern. (LSU unit)

Operation/Procedure
1) Select a target item with scroll key on the touch panel.
2) Enter the print conditions setting value with 10-key.
3) Press [EXECUTE] key.

The print image skew adjustment pattern is printed.

 

61-11

Adjustment

Used  to  correct  the  laser  power  automati-

cally.

Operation/Procedure
1) Select a target item with touch panel key.

2) Press [AUTO CORRECTION] key.
3) Select the adjustment density pattern.
4) Press [EXECUTE] key.
5) The adjustment pattern is printed out.
6) Place  the  printed  adjustment  pattern  on  the  document  table

(A4R direction), and press [EXECUTE] key.
The automatic correction of the laser power is performed, and

then the adjustment result pattern is outputted.

7) To perform the correction again, press [RETRY] key.
8) When [DATA] key is pressed on the initial screen, the display is

shifted to the automatic adjustment result display screen.

 

61-12

Adjustment

Laser power manual correction

Operation/Procedure
Press an item button to be adjusted.
When [MEASURING INSTRUMENT] is pressed:
1) Select the adjustment density pattern.
2) Press [EXECUTE] key.
3) The adjustment pattern is printed out.
4) Enter the adjustment value by the density meter.
5) Press [EXECUTE] key.

Execute  the  manual  correction  of  the  laser  power.  Then  the

adjustment  result  pattern  is  outputted  and  the  data  are  dis-

played.

6) To perform the correction again, press [RETRY] key.
When [VISUAL INSPECTION] is pressed:
1) Select the adjustment density pattern.
2) Press [EXECUTE] key.
3) The adjustment pattern is printed out.
4) Press [4POINT CORRECTION] or [31POINT CORRECTION].
5) Enter an adjustment value.
6) Press [EXECUTE] key.

Execute  the  manual  correction  of  the  laser  power.  Then  the

adjustment  result  pattern  is  outputted  and  the  data  are  dis-

played. 

7) To perform the correction again, press [RETRY] key.
When [DATA] is pressed:
The  display  is  shifted  to  the  manual  adjustment  result  display

screen.

*: Since a special tool is required for measurement, this simulation

 is executed only in the factory.

 

61-13

Adjustment

Used  to  clear  the  laser  power  correction

value.

Operation/Procedure
1) Press [EXECUTE] key.
2) Press [YES] key.
