Precaution

56

• Operate the printer using the power source specified in 

• 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.

• 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.

• 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.

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, 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.

Remove the ink ribbon and the paper tray.

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.

Turn on the printer again. The thermal head moves so 
that you can now install the ink ribbon again.
