To adjust the focus to a distance other than that quoted in the above table,
rotate the focusing ring to the required intermediate position.
8)
When you have focused the scanner to the required distance, there will be a
hole in the Focusing ring that aligns with the hole in the Clamping plate (you
may need to adjust the Focusing ring slightly). Insert and tighten the screw
through the Clamping plate to secure the Focusing ring in position.
9)
Ensure that no combustible dust has entered the enclosure. Check that
the sealing ring is fitted to the end cover and undamaged. Refit and evenly
tighten the four M6 cap head screws and spring washers.
10) Replace the cover panel.
The scanner is now focused.
