Procedure
1. Turn off and unplug the reader.
2. Lift up the hinged door on the front of the reader. Grasp the filter cube and slide it to
the right to remove it from its chamber.
i
Handle with care. The mirrors are seated on a shelf in the bottom of the cube
and are not secured in place.
The Filters and Mirrors chapter shows how to remove and open the filter
cube. It also contains instructions for replacing its contents, if necessary.
3. Set the cube on a flat work surface (do not hold it in your hand). After you remove
the filter cube's top in step 4, the mirrors will fall out if the cube is not on a stable,
flat surface.
4. Using a 7/64" hex key, remove the screw and washer located between the two
emission filter positions (shown in Figure 4-5 on page 50 ). Carefully lift the top off
the filter cube.
5. Wearing linen or cloth gloves, grasp the mirror by its edges and lift it out of the cube.
6. Wet an absorbent towel (such as a Kimwipe, not lens paper) with anhydrous reagent-
grade ethanol. Wear gloves and use enough toweling so that solvents do not dissolve
oils from your hands that can seep through the toweling onto the coated surface.
7. Drag the trailing edge of the ethanol-soaked Kimwipe across the surface of the
mirror, moving in a single direction. A minimal amount of pressure can be applied
while wiping. However, too much pressure will damage the mirror.
8. Use the magnifying glass to inspect the surface; if debris is still visible, repeat with a
new Kimwipe.
9. To replace the mirror, hold it by its edges, turn it so that its label is face-up and
readable, and place it on the shelf in the filter cube. See Figure 4-3 on page 46 .
10. Place the filter cube top back onto the cube and replace the screw and washer.
11. Reinstall the filter cube in the reader.
