Safety advice
Your printer has been developed with the utmost care to ensure
safe, reliable operation over many years. Like all electrical devices,
there are a few basic precautions you need to observe. These pre-
cautions are necessary in the first instance for your own safety but
also protect the printer against any damage. Please read through
the manual carefully and keep it handy.
Make sure...
●the printer is standing on a stable, flat surface. To prevent over-
heating, there should be free space all around the printer; open-
ings should not be covered. Never place the printer directly next
to a radiator or the air outlet of an air-conditioning system. Do
not expose the printer to direct sunlight;
●the printer does not come into direct contact with liquids.
●no objects are pushed into the ventilation slots of the printer as
you run the risk of an electrical shock or could cause a fire;
●you only perform the routine maintenance on the printer de-
scribed in the manual. Opening the case can result in an electri-
cal shock or other harm. Make sure you always remove the plug
from the mains socket before opening the printer case. Do not
alter the printer in any way not described in the manual - this
may cause damage to the printer and result in repairs for which
you will be liable.
Like all electronic devices, the printer can be damaged by electro-
static charges. Static charges can form when walking on unsuitable
floor coverings, for example, and are then transferred to the device
by touching the case. Bear this in mind when choosing the location
for the printer.
Setting up the
printer

XVI
Power supply Ensure yourself ...
●that the ratings of the power supply match the ratings shown on
the back of the printer. If in doubt, ask your supplier;
●that the printer is connected to an earthed mains socket with the
cable supplied;
●when using an extension cable or multiple socket that you do
not exceed the maximum electrical load for this;
●all reasonable precautions have been taken to prevent damage
to the power cable. Do not place objects on the cable and make
sure it is routed so that nobody walks on it or trips over it;
●that a damaged cable is replaced immediately;
●before cleaning the printer or the case, that the power cable is
removed from the power supply. Use only a clean cloth for
cleaning. Do not use liquids or aerosol cleaners;
●you have removed the plug from the mains outlet to ensure
complete isolation from the mains supply. The mains outlet you
are using must be located close to the printer and be easily
accessible.
The three wires of the power cable are colour coded. The earth wire
is yellow-green, the neutral wire is blue and the live current is on
the brown wire.
Servicing / maintenance
Any servicing work on the machine that goes beyond the mainte-
nance described in the manual should be carried out by an author-
ised supplier. We are not liable for damage arising due to unauthor-
ised servicing or through improper maintenance by unauthorised
personnel.

Advice and warning symbols
Observe all warnings and instructions stated on the product itself
and in the accompanying documentation. At particularly impor-
tant points in the manual, warnings are marked with appropriate
symbols.
NOTE: text passages marked thus contain supplementary informa-
tion or instructions.
WARNING - damage: this symbol indicates a possible cause of
damage. Follow all instructions to prevent damage.
CAUTION - risk of injury: this symbol indicates a possible source
of danger. Follow all instructions to prevent injury.
CAUTION - electricity: this symbol indicates a possible source of
danger. Follow all instructions to prevent injury through an electri-
cal shock.
CAUTION - hot: this symbol indicates a possible source of danger.
Follow all instructions to prevent injury through heat.
Should you wish to replace the
ribbon, do not touch the print
head until it has stopped mov-
ing and has cooled down.

XVIII
Meaning of text styles in the manual
To emphasise important passages in the text or differentiate
between the meaning of a printer function and a printer message,
the following text styles or emphases are used in the manual:
●BOLD BLOCK CAPITALS represent the display lamps of the
control panel.
●Bold letters indicate the groups, positions and settings of the
printer menu.
●BLOCK CAPITALS indicate the mode of the printer.
●Italic BLOCK CAPITALS indicate the buttons of the control
panel.
●»Brackets« highlight a printer function.
Consumables / accessories
To ensure that the printer operates perfectly and provides the
proper print quality, we recommend you use only original ribbons
or accessories supplied by us. We accept no liability for damage
resulting from the use of non-original ribbons or accessories which
would have been avoided by using original ribbons or accessories.
Original ribbons and accessories can be purchased from your
supplier.
To ensure good printing results, make sure you keep ribbons and
printing materials (paper, transparencies, etc.) for the shortest time
possible. Materials should be kept no longer than one year.

XIX
Machine-readable fonts
The perfect readability of fonts such as OCR-A, OCR-B or bar codes
(EAN, UPC, Zip) by machines is affected by ...
●the printing technique (resolution, edge sharpness);
●the technical state of the printer;
●the quality of the printing medium (toner, ink ribbon);
●the state of the print material (glossiness, smoothness, coating,
age, reflection, surface uniformity);
●the technical state of the reading device.
Further information
●Leave your printer components in their packing until the manu-
al expressly describes when and how to install them.
●Do not fit or use the serial and parallel interface cables at the
same time.
●Only use a clean cloth to clean the control panel and case.
●The oiling and greasing of moving parts by the user is unneces-
sary.
●If the machine is damaged, switch it off and remove the plug
from the outlet socket. Immediately arrange for it to be repaired.
●Before contacting your supplier’s customer service department,
read the notes in Chapter 6. You may incur costs even during the
warranty period if you call on customer service when the cus-
tomer is expected to remedy the fault or defect himself as
described in Chapter 6.
●When sending off the machine, the carrier or insurer will not
accept responsibility for damage due to unsuitable packing.
