Before Using the Scanner
1. 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 where a considerable amount of dust accumulates.
• 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 where ammonia gas is emitted.
• Avoid locations near volatile or flammable materials, such as alcohol or
paint thinner.

• 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: 10 °C to 32.5 °C (50 °F to 90.5 °F)
Humidity:
20% to 80% RH
