This is a page printer which operates by means of a laser. There is no
possibility of danger from the laser, provided the printer is operated
according to the instructions in this manual.
Since radiation emitted by the laser is completely confined within protective housing,the laser beam cannot escape from the machine during
any phase of user operation.
Internal Laser Radiation
Maximum Radiation Power:
1.03 mW at laser aperture of the print head unit
Wavelength:
770–810 nm
This product employs Class IIIb Laser Diode that emits an invisible
laser bea m.
Laser Diode and Scanning Polygon Mirror are incorporated in the print
head unit.
The print head unit is not a field service item.
Therefore, the print head unit should not be opened under any circum-
stance.

limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates,
uses a nd ca n radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that
interferencewill not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interface by one or more of the following measures:
• Reorient or relocate t he receiving antenna.
• Increase the separation between the equipment and the
receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for
help.
This device m ust be used with a shielded interface cable and shielded
network cable. The use of non-shield cables is likely to result in interference with radio communications and is prohibited under FCC rules.

Installation Precautions
Note the following important precautions when selecting a location for
the printer and when c onnecting it to a power source.
Selecting a Location for the Printer
A proper location helps to ensure that your printer provides you with
the long se rvice life for which it is designed. Double-check to make
sure that the location you select has the following c haracteristics.
• Choose a location that is well-ventilated.
• Make sure there is no chance of ammonia or other organic gasses
being generated in the area.
• The power outlet you plan to connect to for power should be nearby
and unobstructed.
• Make sure that the printer is not exposed to direct sunlight.
• Avoid areas in the direct airflow of air conditioners, heaters, or ventilators, and areas subjected to temperature and humidity extremes.
• Choose a sturdy, level surface where the printer will not be exposed
to strong vibration.
• Keep the printer away from any objects that m ight block its heat
vents.
• Do not locate the printer near curtains or other combustible objects.
• Choose an area where there is no possibility of the printer being
splashed with wa ter or other liquids.
• Make sure that the surrounding area is c lean, dry, and free of dust.

Installation Precautions
Power Source
The following are the power source requirements for this printer.
Power supply:
220-240 V at 50–60 Hz
Voltage fluctuation:
220-240 V, ± 10%
Frequency fluctuation:
Within ±3Hz
Note
◆ Use a power source with minimal voltage and frequency fluctuation.
◆ Only use an outlet that i s rated for the voltage capacity specified for this
printer.
◆ Be s ure to plug the power cord all the way into the outlet. The outlet
should be located near the printer and be easily accessible so you can
unplug the power cord immediately should any problem occur.
◆ Make sure the outlet you use is visible, and not hidden behind the printer
or any other object.
◆ If any other e lectrical equipment is plugged into the same outlet, make
sure that the capacity of the outlet is not exceeded.
◆ If you use an e xtension c ord, make sure its capacity is greater than the
power consumption of the printer. Using an extension cord with a lower
capacity creates the danger of fire.
◆ Never use a multiple socket to connect other appliances or machines to
the same outlet being used to power the printer.
