Notes:
1. Do not leave fingerprints or stain on the
slit glass [1] .
2. Pay close attention not to make an impact
or vibration on the laser optical unit
because it is a precise apparatus.
3. Place the removed laser optical unit so as
not to load on the polygonal motor.
4. Do not disassemble the laser optical unit
in the field because it is precisely
adjusted and very sensitive to dust and
stain.
5. Do not take off the laser driving board
(LDR board) [1] or the SNS board [2]
installed in the laser optical unit, or loosen
the screws.
