Important Safety Instructions
To ensure the safe operation of this scanner, be sure to read the
safety warnings and precautions described below.
Installation Location
The performance of this scanner is affected by the environment in which it
is installed. Make sure that the location where the scanner is installed
meets the following environmental requirements.
●
Provide adequate space around the
scanner for operation,
maintenance, and ventilation.
●
Avoid installing the scanner in
direct sunlight. If this is
unavoidable, use curtains to shade

dust.
4.3" (110 mm) or more
●
Avoid warm or humid locations,
such as in the vicinity of a water
faucet, water heater, or humidifier,
and avoid locations where the
fumes from ammonia, paint thinner,
or other volatile chemicals may be
present.
●
Avoid locations that are unstable or
subject to vibration.
●
Avoid exposing the scanner to rapid
changes in temperature. If the room
in which the scanner is installed is
cold but rapidly heated, water
droplets (condensation) may form
inside the scanner. This may result
in a noticeable degradation in
scanning quality. The following
conditions are recommended for
optimal scanning quality:
Room temperature: 50°F to 90.5°F
(10°C to 32.5°C)
Humidity: 20% to 80% RH

Avoid installing the scanner near
equipment that generates a
magnetic field (e.g., speakers,
televisions, or radios).
