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. 100mm (3.94") 100mm (3.94") 100mm (3.94") ● When scanning documents using the straight path, provide adequate space in back of the scanner for scanned document output. ● 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 as dust may adversely affect the inside of the scanner. ● Avoid warm or humid locations, such as in the vicinity of a water faucet, water heater, or humidifier. Avoid locations where ammonia gas is emitted. Avoid locations near volatile or flammable materials, such as alcohol or paint thinner. ● 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: 10 °C to 32.5 °C (50 °F to 90.5 °F) Humidity: 20% to 80% RH ● Avoid installing the scanner near equipment that generates a magnetic field (e.g. speakers, televisions, or radios.) AC Adapter ● Connect only to a power outlet of the rated voltage and power supply frequency (120 V, 60 Hz or 220-240 V, 50/60 Hz depending on your region). ● Do not connect other electrical equipment to the same power outlet to which the scanner is connected. Also, when using an extension cord, make sure that the extension cord is rated for the current requirements of the scanner. ● Never try to take the AC adapter apart or modify it in any way, as this is dangerous. ● The power cord may become damaged if it is often stepped on or if heavy objects are placed on it. ● Do not use the power cord while it is coiled. ● Do not pull directly on the power cord. When disconnecting the power cord, grasp the plug and remove it from the outlet. ● Keep the area around the power cord clear of objects so that the power cord can be disconnected easily in an emergency. ● Do not use an AC adapter other than the one provided with the scanner. Do not use the AC adapter provided with the scanner with other products. ● If you have any questions regarding the power supply, contact your local authorized Canon dealer or service representative for further information. 18
