Installing the optics wire
CAUTION Be sure the power cord has

When winding the optics
wire around the pulley, be
sure to run the wire tightly
so that it does not ride on
the side of the pulley.
Then re-tensioning or
replacing the optics wire,
be sure to use the optics
positioning tool.
Be sure to perform image
adjustment after replacing
or re-installing the wire.
