Important Precautions and Safety Information
When using this machine, these basic safety precautions should always be followed
to reduce risk of fire, electric shock and injury to people:
1. Read and understand all instructions.
2. Use common sense whenever operating electrical appliances.
3. Follow all warnings and instructions marked on the machine and in the literature
accompanying the machine.
4. If an operating instruction appears to conflict with safety information, heed the
safety information. You may have misunderstood the operating instruction. If you
cannot resolve the conflict, contact your sales or service representative for
assistance.
5. Unplug the machine from the AC wall socket and/or telephone jack before
cleaning. Do not use liquid or aerosol cleaners. Use only a damp cloth for
cleaning.
6. Do not place the machine on an unstable cart, stand or table. It may fall, causing
serious damage.
7. Your machine should never be placed on, near or over a radiator, heater, air
conditioner or ventilation duct.
8. Do not allow anything to rest on the power. Do not locate your machine where
the cords will be abused by persons walking on them.
9. Do not overload wall outlets and extension cords. This can diminish performance,
and may result in the risk of fire or electric shock.
10. Do not allow pets to chew on the AC power, telephone or PC interface cords.
11. Never push objects of any kind into the machine through case or cabinet
openings. They may touch dangerous voltage points, creating a risk of fire or
shock. Never spill liquid of any kind onto or into the machine.
12. Your machine may have a heavy cover for optimal pressure on the document for
the best scanning and/or faxing (usually the flatbed-type machine). In this case,
replace the cover after placing document on the scan glass, by holding and
moving it down slowly until it seats on its location.
13. To reduce the risk of electric shock, do not disassemble the machine. Take it to a
qualified service technician when repair work is required. Opening or removing
covers may expose you to dangerous voltages or other risks. Incorrect
reassembly could cause electric shock when the unit is subsequently used.
14. Unplug the machine from the telephone jack, PC and AC wall outlet and refer
servicing to qualified service personnel under the following conditions:
• When any part of the power cord, plug or connecting cable is damaged or
frayed.
• If liquid has been spilled into the machine.
• If the machine has been exposed to rain or water.
• If the machine does not operate properly after instructions have been followed.
• If the machine has been dropped, or the cabinet appears damaged.
• If the machine exhibits a sudden and distinct change in performance.
