5.1 OPTICS ANTI-CONDENSATION HEATER INSTALLATION
(OPTION)
[B]
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
Unplug the copier power cord before starting the following procedure.
1. Remove the rear cover. (See "Replacement and Adjustment - Exterior
Cover Removal".)
2. Remove the exposure glass. (See "Replacement and Adjustment -
Exposure Glass Removal".)
3. By using the timing belt [A], manually move the 1st and 2nd scanner units
away from the home position.
NOTE: Move the scanners by using the timing belt as shown in the
diagram. Do not handle the scanners directly.
