PRECAUTIONS FOR INSTALLATION

• Do not use or store the equipment in a place exposed to fire, moisture, or direct sunshine, or in a

place near a heater or 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 or use 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.

• Install the printer on a flat, stable desk or table that is free from vibration, in a well-ventilated place.

• Do not install the printer at a location where its operation could be hindered.

• Do not place anything on the printer or leave small objects, like a clip or pin, around it. A foreign

object could cause trouble if it gets inside.

• Do not use any sharp-pointed object, such as a pen, for example, to touch the operation panel of the

printer. It could cause trouble.

• 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 the equipment only at the specified power supply, voltage and frequency. Otherwise, it may

emit smoke and catch fire or cause other problems.

• Connect only the specified power source. Use of an unspecified power source could cause trouble

or smoke/fire.

• Confirm that a plug socket used for connection has sufficient capacity.

• Avoid connecting a power cable to a plug socket shared by other devices or extending the wiring

too far. It may result in the cable catching fire or a power outage. Also, do not step on or apply an
excessive force (Pull, load) to the cable, and do not use the printer with such a force applied to it.

• Never connect a grounding cable (Frame ground) to a gas pipe. There is a danger of explosion.

When connecting or disconnecting the grounding cable, be sure to disconnect the power cable and
the power plug from the plug socket.

• When connecting/disconnecting the cables, be sure to turn off the power first, including the

connected side, and then connect/disconnect them, holding a plug and a connector. Pulling the
cable itself could cause it to snap or become damaged.

• Connect a power cable or a connector cable securely. If a reverse-polarity connection is made,

internal elements may be broken or a mating device may be adversely affected.

• Use a shielding wire or twisted pair wire for a signal line, in order to minimize noise effect. Do not

route the cable too long or connect it to a noisy device. Connection to a noisy device could cause
erroneous printing due to corrupt data, and so on.

• 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.

• When the equipment will not be used for a long period of time, unplug it and remove the paper roll

from it.
