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 machine in direct sunlight. If
this is unavoidable, use curtains to shade the
scanner.
● Avoid locations with excessive dust or cigarette
smoke. Dust and smoke can have negative effects
on the inner parts of the scanner.
● 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 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: 15 °C to 30 °C (59 °F to
86 °F)
Humidity: 25% to 80% RH
● Avoid installing the scanner near equipment that
generates a magnetic field (e.g. speakers,
televisions, or radios).
Removing the Transportation Screw
Three transportation screws are preinstalled at the factory to
secure the scanner’s optical unit and protect it from damage
caused by vibration and shock during shipment. Make sure to
remove these screws before using the scanner.
