USER’S GUIDE
CHAPTER 1–6
OPERATING AND STORAGE ENVIRONMENT
Please take note of the following before using the printer.
Power Supply
Use the printer within the specified power range.
AC power: ±10% of the rated power voltage in your country
Frequency: 50 Hz (220 V– 240 V) or 50/60 Hz (110–120 V)
The power cord, including extensions, should not exceed 5 meters (16.5
feet).
Do not share the same power circuit with other high-power appliances,
particularly an air conditioner, copier, shredder and so on. If it is
unavoidable that you must use the printer with these appliances, it is
recommended that you use an isolation transformer or a high-frequency
noise filter.
Use a voltage regulator if the power source is not stable.
Environment
The printer should be installed near a power outlet, which is easily
accessible.
Use the printer only within the following ranges of temperature and
humidity.
Ambient temperature: 10°C to 32.5°C (50°F to 90.5°F)
Ambient humidity: 20% to 80% (without condensation)
The printer should be used in a well ventilation room.
Place the printer on a flat, horizontal surface.
Keep the printer clean. Do not place the printer in a dusty place.
Do not place the printer where the ventilation hole of the printer is
blocked.
Do not place the printer where it is exposed to direct sunlight. Use a blind
or a heavy curtain to protect the printer from direct sunlight when the
printer is unavoidably set up near a window.
Do not place the printer near devices that contain magnets or generate
magnetic fields.
