PRECAUTIONS FOR INSTALLATION
• Do not use or store the equipment in a place exposed to fire, moisture, or direct sunlight, or in a place
near a heater or a thermal device where the prescribed operating temperature and humidity are not met,
or in a place exposed to much oil, iron powder, or dust. The equipment may become out of order, emit
smoke, or catch fire.
• Do not install the equipment in a place like a laboratory where chemical reactions are expected, or in a
place where salt or gases are contained in the air. There is a danger of fire or electric shock.
• Firmly secure the equipment onto a flat and stable mounting panel free from vibrations and angled at 0°
to 90° in a well-ventilated place.
• Do not install or use the equipment in a place where its operation could be hindered.
• Do not place anything on the equipment, as it can lead to problems.
• Use accessory fittings and screws to secure the equipment. Tighten the screws firmly and properly.
Excessive tightening can result in problems or damage.
• Do not use the equipment near a radio or TV receiver. Do not share the power from a plug socket a
radio or TV receiver is connected to. It may cause a reception problem.
• Use only power of the specified voltage and current capacity. Be careful not to mistake polarity.
The equipment may become out of order, emit smoke, or catch fire.
• Confirm that a plug socket used for connection has sufficient capacity.
• Avoid composite wiring with a power cable or excessively extended wiring. Excessive electric current
may cause heat generation/ignition of the supply line or shut off the power. Do not step on a cable or
use the equipment with excessive force (tension, load) applied to it.
• Never connect a grounding cable to a gas pipe. There is a danger of explosion. When connecting or
disconnecting the grounding cable, be sure to disconnect the power plug from the plug socket.
• When disconnecting/reconnecting the cables, be sure to turn off the power, including the mating side.
• Connect a connector cable securely. If a reverse-polarity connection is made, internal elements may be
broken or a mating device may be adversely affected.
• Avoid routing a signal line too long or connecting to any noisy device, to protect against such effects as
data deformation due to noise.
• Use the equipment in an environment where there is a plug socket near the main body and you can
easily disconnect the power plug from it, to shut off the power.
• Keep the equipment in the printing-head-up state when transporting the equipment or when it will not
be used for a long time.
• When transporting the equipment, remove the rolled paper from it.
