CHAPTER TWO
Assembly
Whenever you transport the MFC, use the packing materials that came
with your MFC and pack the MFC correctly.

6CHAPTER TWO
Choosing a Location
Place your MFC on a flat, stable surface, such as a desk. Select a place
that is free of vibration and shocks. Locate the MFC near a standard,
earthed electrical socket. Choose a location where the temperature
remains between 10°C and 32.5°C.
Avoid placing your MFC where it may be knocked. Do not place near
heaters, air conditioners, water, chemicals, or refrigerators. Do not
expose the MFC to direct sunlight, excessive heat, moisture, or dust. Do
not connect your MFC to electrical outlets on the same circuit as large
appliances or other equipment that might disrupt the power supply. Avoid
interference sources, such as speakers or the base units of cordless
phones. Ensure the airflow from the fan on the right hand side of the
MFC is not impeded.
Caution
Keep the MFC out of strong light such as direct sunlight.
