Canon MF211 Manual page 8

This machine generates a slight amount of ozone, etc. during normal use. Although sensitivity to ozone, etc. may vary, this
amount is not harmful. Ozone, etc. may be more noticeable during extended use or long production runs, especially in poorly
ventilated rooms. It is recommended that the room where the machine operates be appropriately ventilated to maintain a
comfortable working environment. Also avoid locations where people would be exposed to emissions from the machine.
Do not install in a location where condensation occurs
Water droplets (condensation) may form inside the machine when the room where the machine is installed is heated rapidly, and
when the machine is moved from a cool or dry location to a hot or humid location. Using the machine under these conditions may
result in paper jams, poor print quality, or damage to the machine. Let the machine adjust to the ambient temperature and
humidity for at least 2 hours before use.
When using wireless LAN (MF212w)
Set the machine at a distance of 50 m or less from the wireless LAN router.
Do not set machine in a location where any object blocks communication. The signal may be degraded when passing through
walls or floors.
Keep the machine as far as possible from digital cordless phones, microwave ovens, or other equipment that emit radio waves.
In altitudes of 3,000 m or above sea level
Machines with a hard disk may not operate properly when used at high altitudes of about 3,000 meters above sea level, or
higher.
