Miscellaneous

Precautions

In addition to the following precautions, be sure to refer to 
the safety warnings and notices at the beginning of this 
manual.

Safety

If “CLEAN HEAD” appears on the LCD display

The message “CLEAN HEAD” appears on the LCD 
display when the number of printed pages reaches 1,000 
and it is time to clean the thermal head. For details about 
cleaning, see “Cleaning the thermal head” on page 22.
When the message “CLEAN HEAD” appears, you can 
cancel it by pressing any button on the front of the printer.
The message reappears each time you turn the printer on 
until cleaning has been performed.
Also, the “CLEAN HEAD” message display setting can be 
turned on or off in the setup menu (page 18).

If “CLEAN ROLL” appears on the LCD display

If all paper in the paper feed tray is used up during a 
printing operation, the printer executes automatic paper 
feed roller cleaning. If the internal sensor detects an 
excessive amount of dust on the paper feed roller, 
“CLEAN ROLL” appears on the LCD display. In this case, 
perform manual paper feed roller cleaning. For details, see 
“Manual paper feed roller cleaning” on page 22.
The message about roller cleaning appears at the end of 
printing if the paper feeding power is low.

Installation

Avoid placing the unit in a location subject to:
• direct or excessive sunlight
• high humidity
• extremely high or low temperatures
• mechanical vibration
• excessive dust
• instability
Do not obstruct the ventilation holes on the side of the unit, 
as it may damage the unit or cause a fire hazard.
For safety, do not place an object, such as a computer 
monitor, on top of the unit.

Transportation

When transporting the printer, follow the steps below to 
remove all accessories and repack the unit in its original 
packaging. Transporting the printer with the accessories 
installed may damage the printer.

1

Remove the ink ribbon and paper feed tray.

2

Lock the internal thermal head.

1

Press the 

!

 POWER switch to turn on the printer.

2

Simultaneously press 

<

, 

,

, and the MENU 

button. 
The printer operation sound continues for 
approximately 2 seconds, and the message 
“WAIT” appears on the LCD display.

3

When the printer operation sound stops and the 
message “TRANS MODE” appears in the 
display, press the 

!

 POWER switch to turn off 

the printer. 
The thermal head is locked.

To unlock the thermal head

Turn on the printer again. The thermal head unlocks, and 
the ink ribbon can be loaded.

When the printer will be inactive for a long time

• Press the 

!

 POWER switch to turn off the printer, and 

then disconnect the power cord.

• Remove the partially used paper and ink ribbon from the 

printer, reseal them in their original bags, and store them 
in a cool, dark location. Before unsealing and reusing the 
stored paper and ink ribbon, allow them to return to room 
temperature to prevent water condensation.

On condensation

• If the printer is subjected to wide and 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 quantities 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 moisture 
condensation forms, turn off the power and leave the 
printer standing for at least one hour.

• If the printing pack is subjected to wide and sudden 

changes in temperature, condensation may form on the 
ink ribbon or paper inside. 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.

Cleaning

Note

Before you clean the printer, be sure to turn off the power 
and disconnect the power cord.

When the cabinet becomes dirty

Clean the cabinet, panel and controls with a soft dry cloth, 
or a soft cloth lightly moistened with a mild detergent 
solution.
Do not use any type of solvent, such as alcohol, benzene or 
a chemical cloth, which may damage the finish.
