Laser Cartridge Installation
1) Make sure that your power cord IS NOT
plugged in at this time. Press on the backside of
the two hinges to release the latch. Gently fold
back the rear cover.
3) Observe the "V" groove along the upper (3)
and lower (2) part of the laser cartridge and the
alignment plate (1) at the end.
INSTALLATION
2) Visually locate the two mounting blocks (1),
the laser latch (2), alignment fork (3), and power
connector (7). Notice that the alignment fork has
two plates, one small (4) and one large (5).
Locate the gap between the two plates (6).
4) Pick up the laser cartridge by the sides and
tilt it downward on a 30-degree angle. Mount
the cartridge onto the mounting blocks by
placing the upper "V" groove on top of the
mounting blocks. Slide the cartridge to the right
until the OUTER EDGE of the alignment plate
contacts the INSIDE EDGE of the large plate of
the alignment fork.
