PRECAUTIONS WHEN INSTALLING THE PRINTER
Prior to operation, read the safety instructions carefully and observe them.
Do not use or store the printer near fire, excessive moisture, in direct sunlight, near an
air conditioner or heater or other source of unusually high or low temperature or
humidity or excessive dust.
Do not place the printer where chemical reactions occur, such as in a laboratory.
Do not place the printer where air is mixed with salt or gas.
The printer must sit on a firm, level surface where there is ample ventilation. Never
allow the printer’s air vent to be blocked by a wall or other object.
Do not put anything on the top of printer.
Do not place the printer near a radio or television, and do not use the same wall outlet
for the printer and radio or television. Radio or television reception could be adversely
affected.
Do not use a power voltage or frequency other than those specified.
Do not put anything on the power cord or step on it.
Do not drag or carry the printer with the power cord or interface cable.
Avoid plugging the power cord into an outlet with many loads.
Do not bundle the power cord when inserting the plug.
Always grip the plug housing, not the cord, to plug/unplug the power cord.
Make certain the power is turned off before connecting/disconnecting the interface
cable.
Avoid lengthening the signal cable or connecting it to any noise-producing device. If it
is unavoidable, use the shielded cable or twisted pair for each signal.
Place the printer near the outlet where the power cord can be unplugged easily to shut
off power.
Use the AC outlet that accepts a three-pronged plug. Otherwise, static electricity may
be generated and there will be danger of electric shock.
MAKING THE EQUIPMENT ELECTRICALLY SAFE
1.
Put the main power switch of the equipment to the "O" (OFF) position, to power
down the equipment.
2.
Disconnect the printer power cord from the power supply grid outlet of
the site or from the printer power socket.
