3. LASER
Laser Output Adjustment
*If you replaced the laser scaner unit, enter the value on the laser scaner unit.
Sub item
PVE-OFST
Used to enter the adjusted value of the laser irradiation position.
Adjustment method
- If you have cleared the DC controller PCB's RAM or replaced the DC controller PCB, enter
the value on the service label.
Adjustment range -25 to 25 [Factory default/After RAM clear: 0]
Reference:
This item is to enable input of the factory-adjusted value, and should not be adjusted in the
market.
LDADJ1-Y*
A-B laser reproduction ratio (Y)
B laser reproduction adjustment value (Y) based on the A laser reproduction ratio of the laser
scanner unit
Unless an appropriate value is entered here, reproduction ratios of the laser A and B become
different, resulting in exposed images of different reproduction ratios.
Setting range: -512 ~ 511
[Factory default value /post-RAM clear value: 0]
LDADJ2-Y*
A-C laser reproduction ratio (Y)
C laser reproduction adjustment value (Y) based on the A laser reproduction ratio of the laser
scanner unit
Unless an appropriate value is entered here, reproduction ratios of the laser A and C become
different, resulting in exposed images of different reproduction ratios.
Setting range: -512 ~ 511
[Factory default value /post-RAM clear value: 0]
LDADJ3-Y*
A-C laser reproduction ratio (Y)
C laser reproduction adjustment value (Y) based on the A laser reproduction ratio of the laser
scanner unit
Unless an appropriate value is entered here, reproduction ratios of the laser A and C become
different, resulting in exposed images of different reproduction ratios.
Setting range: -512 ~ 511
[Factory default value /post-RAM clear value: 0]A-D laser reproduction ratio (Y)
D laser reproduction adjustment value (Y) based on the A laser reproduction ratio of the laser
scanner unit
Unless an appropriate value is entered here, reproduction ratios the laser of A and D become
different, resulting in exposed images of different reproduction ratios.
Setting range: -512 ~ 511
[Factory default value /post-RAM clear value: 0]
LDADJ4-Y*
A-D laser reproduction ratio (Y)
D laser reproduction adjustment value (Y) based on the A laser reproduction ratio of the laser
scanner unit
Unless an appropriate value is entered here, reproduction ratios the laser of A and D become
different, resulting in exposed images of different reproduction ratios.
Setting range: -512 ~ 511
[Factory default value /post-RAM clear value: 0]A-B laser phase difference (Y)
A-B inter-laser phase difference (exposure start timing) adjustment value (Y) of the laser
scanner unit
Unless an appropriate value is entered here, A and B laser phases (exposure starting position)
become different, resulting in faulty exposed image
Setting range: 0 ~ 1023
[Factory default value /post-RAM clear value: 0]
