NOTE: The optics anti-condensation heater keeps water from condensing on the
copier's mirrors.
Such condensation occurs at cold temperatures with high humidity, and
causes the first few copies of the day to be dark, or even black.
The heater is available as a service part. (See the parts catalog.)
CAUTION

1. Remove the exposure glass. (See "Replacement and Adjustment - Exposure
Glass Removal".)
2. Remove the rear cover. (See "Replacement and Adjustment - Outer Cover
Removal".)
3. Insert the two clamps [A] as shown.
4. Mount the anti-condensation heater [B] (2 screws).
5. Pass the connector [C] through the opening [D].
6. Clamp the harness [E] to the two clamps [A].
