Precaution
Safety
• Operate the printer using the power source specified in
“Specifications” on page 58.
• Be careful not to damage the AC power cord by
placing or dropping heavy objects on it; it is dangerous
to use the unit with a damaged AC power cord.
• If you do not intend to use the unit for a long time,
disconnect the AC power cord.
• Unplug the AC power cord by grasping the plug, not
the cable itself.
• Do not disassemble the unit.
• Do not remove the cover. There is a danger of electric
shock from the internal parts.
• Be careful not to spill water or other liquids on the
unit, or to allow combustible or metallic material to
enter the cabinet. If used with foreign matter in the
cabinet, the unit is liable to fail, or present a risk of fire
or electric shock.
• Ventilation holes are provided to prevent the unit from
overheating. Be careful not to obstruct them with other
units or by covering the unit with a cloth, etc.
• If the unit malfunctions or if a foreign body falls into
the cabinet, disconnect the AC power cord
immediately and consult your Sony service facility or
your Sony dealer.
Installation
• Avoid placing the unit in a location subject to:
– mechanical vibration
– high humidity
– excessive dust
– direct or excessive sunlight
– extremely high or low temperatures
• Do not use other electronic equipment near the unit.
The unit will not work properly in strong
electromagnetic fields.
• Do not place a heavy object such as a monitor on the
printer.
Condensation
• If the printer is subject to wide or sudden changes in
temperature, such as when it is moved from a cold
room to a warm room or when it is left in a room with
a heater that tends to produce large amounts of
moisture, condensation may form inside the printer. In
such cases the printer will probably not work properly,
and may even develop a fault if you persist in using it.
If condensation forms, turn off the power and leave the
printer to stand for at least one hour.
• If the printing pack is subjected to wide or sudden
changes in temperature, condensation may form on
the ink ribbon or paper. This will cause the printer to
malfunction. Also, if the printing pack is used in this
state, spots are likely to appear on the printout.
Therefore, avoid storing the printing pack in locations
subject to wide or sudden changes of temperature.
• To store a half-used printing pack, replace it in its
original packing and reseal the package. If possible,
keep the sealed printing pack in a cool, dark location.
To subsequently use the printing pack, place it, in its
sealed package, in a warm room for several hours.
Doing so prevents condensation from forming when
the printing pack is removed from its package.
Location
To prevent internal heat built-up, leave enough room
around the printer for air to circulate through the vents
on the left hand side and top of the cabinet.
Before Transporting the Printer
Before transporting the printer, use the following
procedure to remove the supplied accessories and then
put them back into their original packing. Transporting
the printer with the supplied accessories still installed
may cause malfunctions.
1
Remove the ink ribbon and the paper tray.
2
Secure the internal thermal head, as follows:
1 Turn on the printer.
2 Press the G and g cursor keys and the MENU
button simultaneously.
The printer operating tone sounds for about two
seconds. For the UP-21MD, the message
“TRANSPORT MODE” appears on the printer
window display, too.
3 When the printer operation tone stops
sounding, turn off the power of the printer.
The thermal head is now secured.
To release the thermal head
Turn on the printer again. The thermal head moves so
that you can now install the ink ribbon again.
