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.
It may expose you to electric shocks or cause a fire.
• 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.
