Laser Optics Housing Unit
First, prepare the new laser optics housing unit.
Then, before you switch the machine off, you must make
some SP adjustments.
These adjustments move the 2nd mirror positioning motors
back to home position.
If this is not done, the motors in the new unit will be at the
home position, but the SP setting could be different. This
could cause errors in skew correction.
After you install the new unit, you will do the forced line
position adjustment, and this will set up the motors and SPs
correctly.
Note: If you forget to do these SP adjustments, there is a
recovery procedure in the manual.
Then you can remove the old unit and install a new one.
After you install the new unit, do the SP adjustments, and
the line position adjustment, as explained in the manual.
