2-3. Handling Care
1. Be careful not to drop paper clips, pins or other foreign matter into the unit
as these cause the printer to malfunction.
2. Do not attempt to print when either paper or ribbon cartridge is not located
in the printer, otherwise the print head can be damaged.
3. Do not open the cover while printing.
4. Do not touch the print head immediately aer printing as it gets very hot.
5. Use only roll paper that is not glued to the core.
6. When the paper end mark appears on the paper, replace the roll paper before
it runs out.
WARNING
PShut down your equipment immediately if it produces smoke, a strange
odor, or unusual noise. Immediately unplug the equipment and contact
your dealer for advice.
PNever attempt to repair this product yourself. Improper repair work can be
dangerous.
PNever disassemble or modify this product. Tampering with this product
may result in injury, re, or electric shock.
PDuring and immediately aer printing, the area around the print head is
very hot. Do not touch it, as you could be burned.
CAUTION
P
We recommend that you unplug the printer from the power outlet
whenever you do not plan to use it for long periods. Because of this, you
should locate the printer so that the power outlet it is plugged into is
nearby and easy to access.
P
If the voltage shown on the label on the of your printer does not match the
voltage for your area, contact your dealer immediately.
P
Make sure that the printer is turned o and unplugged from the AC outlet
and that the computer is turned o before making connections.
P
Do not connect a telephone line into the modular connector.
PDo not pull out paper while the printer cover is closed.
PIf liquids, foreign objects (coins and paper clips), and so on enter the
printer, turn o the printer, unplug it from the AC outlet, and contact your
dealer for advice. Continued use could cause a short circuit, which may
result in re or electric shock.

2-4. Maintenance
Essentially, your printer is a robust piece of equipment, but should be treated
with a modicum of care in order to avoid malfunctions. For example:
1. Keep your printer in a “comfortable” environment. Roughly speaking, if you
feel comfortable, then the environment is suitable for your printer.
2. Do not subject the printer to physical shocks or excessive vibration.
3. Avoid over-dusty environments. Dust is the enemy of all precision
mechanical devices.
4. To clean the exterior of the printer, use a cloth barely dampened with either
water with a little detergent or a little alcohol, but do not allow any liquid to
fall inside the printer.
5. The interior of the printer may be cleaned with a small cleaner or a
compressed-air aerosol (sold for this purpose). When performing this
operation, be sure not to bend or damage any cable connections or electronic
components.
