Installing a new Laser Optics Housing Unit
A new laser optics housing unit has a bracket to protect the LD units. When you
install the new unit, do not remove the bracket until near the end of the installation
procedure (the correct time is stated in the manual).
This bracket protects a capacitor on the unit. If the bracket is removed too early,
you could break the capacitor on the corner of the mainframe when you install the
new unit.
1. Push the new laser optics housing unit [A] slowly into the mainframe until the bracket
[B] bumps against the frame of the mainframe.
2. Remove the bracket [B], and then push the new laser optics housing unit fully into the
mainframe ( x 2, All 's, = x 3).
3. Reassemble the mainframe.
