Installation
➤ Unpacking the printer
Place your printer on a solid base (see
Placing your
printer
).
Make sure that the “Up” symbols point to the correct
direction.
Open the packaging and take out the ribbon cassette. Pull the printer out of the cardboard box towards
you and remove the remaining packaging material.
Check the printer for any visible transport damage
and completeness. Apart from this CD-ROM (➀), the
Operator’s Manual (➁), the power cable (➂), the ribbon (➃) and the paper support (➄) must be included.
If you find any transport damage or if any accessories are missing, please contact your dealer.

➤ Placing your printer
Place the printer on a solid, flat and non-slip surface
in such a way that it cannot fall down. Make sure to
facilitate access to the control panel and the paper input trays and to leave sufficient space for the paper
ejected.
When selecting the printer location, observe the following additional instructions:
Never place the printer in the vicinity of easily inflammable gas or
explosive substances.
The power supply cable may be damaged
if the paper edges constantly chafe the
insulating sheath. The user must always
ensure that there is sufficient distance
between the power supply cable and the
paper.

Do not expose the printer to direct sunlight. If you cannot avoid placing the
printer near a window, protect it from the sunlight with a curtain.
When connecting the computer with the printer, make sure not to exceed the
permitted cable length (see
Technical specifications
).
Ensure sufficient distance between the printer and any heating radiators.
Avoid exposing the printer to extreme temperature or air humidity
fluctuations. Protect the printer from dust.
It may be recommended to install the printer in a place which is acoustically
isolated from the workplace because of the noise it may produce.

➤ Checking the printer
voltage
Make sure that the device has been set to the correct voltage (e.g. 230 V
in Europe, 120 V in the USA). To do this, check the type plate above the
power inlet at the back of the printer. Contact your dealer if the setting is
incorrect.
Never switch on the printer if the voltage setting is incorrect, since
this may result in severe damage.
You can set the printer to the correct mains voltage
yourself. To do this, cautiously tilt the printer to the
rear.

The control panel
The control panel with its keys is used for controlling your work with the
printer. The control panel is located on the front left side of your printer
and consists of a two-line LC display and six keys.
The functions of the keys depend on the printer’s current mode (status).
There are four basic modes.
The
Online mode
is the printer’s normal operating status. Data from your
computer can be received and printed.
In the
Offline mode
the link between printer and computer is interrupted,
i.e. no data can be received and printed.
In the
Setup mode
you can either select the printer menu or carry out the
so-called quick-switch function. The quick-switch option was included so
that you can change the most important parameters (adjustments,
character density, font, paper path, adjustments i.e. head gap) directly
without having to enter them via the menu. The character density and
font parameters can also be set permanently in the printer menu mode.
In the
Menu mode
further printer settings (line spacing, size of the inter-
face buffer etc.) can be altered and saved permanently.

➤ The LC display The LC display tells you all the important printer settings and informs you
which functions are currently assigned to which keys.
In Normal mode the upper line tells you the printer’s status (
Online
or
Offline
mode – in the example below the printer is in the Online mode),
and the selected paperpath (below: Tractor1 = tractor mode).
The second line informs you which functions are currently assigned to
which keys. The word or symbol directly above a key tells you the
current function of the key. In our example the right key is assigned with
the Tear function. If you were to press this key the loaded fanfold paper
would be advanced to the tear position.

You can activate one of the functions below by keeping the corresponding key or key combination pressed while turning on the printer:
If you keep the Online key depressed while turning on the printer, you
enter the printer’s Self-Test mode. The Self-Test mode is described in
the section
Test functions
of this manual.
If you keep the Setup key depressed while turning on the printer, you regain access to the printer menu if you had locked it before with the help
of the MenLock function. The MenLock function is described in the

If you keep the key 4 depressed while turning on the printer, a
status page is printed out from the active paper source with the
selected settings of all menus (see Printing status page).

Changing the ribbon cassette
The ribbon consists of a dense synthetic fabric saturated with ink. When
printing, the needles hit the ribbon and transfer the ink particles on to the
paper. After printing several million characters, the ink is consumed and
the fabric worn out.
Remove all the paper from the printer and make
sure that the printer is switched off before opening
the cover.
Press the two slide latches, raise the top cover to an
angle of 90 degrees relative to the top cover of the
printer and remove it.
