Conditions for Power Supplies
• The following conditions apply to the power supplies of printers:
Alternate Current (AC) : 100 V ±10%
Power Supply Frequency : 50, or 60 ±2 Hz
• For unstable power supplies, use voltage regulators etc.
• The maximum power consumptions of printers are 1,500 W. Be sure power supplies have power
supply capacities adequate for the printers.
• Make sure to turn off printers before attaching and detaching power supply cords and grounding
wires to the printers. Keeping the power supply ON causes a fire or an electric shock.
• Grounding wires must be connected to dedicated grounding terminals. No grounding wires
causes a fire or an electric shock. Consult with a dealer if grounding wires is impossible.
• Never connect the ground wires to water or gas pipes, or telephone grounds, lightning conductors
or other lines. They cause a fire, an electric shock or a gas explosion.
• Always hold a plug while inserting or removing the power supply cord. Damaged cord is a result
of pulling it, which causes a fire or an electric shock.
• Do not insert or pull out power supply plugs with wet hands. Make sure the power supply cord is
well inserted. Otherwise causes a fire or electric shock.
• Do not insert or pull out the power supply plugs with wet hands. It causes an electric shock.
• Do not step on the power supply cord or put the things on them. Otherwise damages the cord and
causes a fire and an electric shock.
• Do not tie the power supply cords in a bundle in use of the printer. It heats up and damages the
cord, which is a result of a fire and an electric shock.
• Do not use the damaged power supply cords. It causes a fire or an electric shock.
• Do not use star-burst connections for printers.
• Do not connect a printer to the same receptacle outlet being used for electrical equipment other
than the printer. Connecting a printer such a receptacle outlet, particularly being used for air
conditioning, copying or shredding equipment, may cause a malfunction in the printer due to
electrical noises. If a printer is connected to such a receptacle outlet by necessity, use a
commercially available noise filter or noise-cut transformer.
• Do not use the extension cords. Normal printer operation may not be attained if using an extension
cord due to the decreased AC voltage. If necessary, select the cord, which is rating 100 V, 15 A
and more. Other types of cords cause a fire or an electric shock.
• Do not turn off the printer or pull out the power supply plugs while the printer are in use. It causes
of a broken down of printer or an electric shock.
• Please disconnect printers from the mains supply if they will not be used for an extended period
of time for safety.
• Use only those attached cord.
Using other types of cords cause a fire or an electric shock.
• Do not use an attached cord to other appliances due to a fire or an electric shock.
It may expose you to electric shocks or cause a fire.
Well explanation and showing the customers a user’s manual avoids any troubles.
