5. CONFIRM OPTICAL POWER SETTING PARAMETER
LD Test result is ok, but Loader performance is bad.
1. Check ALPC parameter value
1) Press button to open ‘Results Display’ dialog.
2) Press button.
- We can see optical power setting value.
- Write optical Power Setting value to paper.
- Adjust power setting again.
- Compare original parameter to new parameter.
- if parameter value is different highly, original
value is wrong or optical power may change.
- But pick-up LD test is all ok , just adjust optical
power setting again.
Normal range of ALPC parameter
Optical power value which has been saved in the
EEPROM
