User guide Introduction
Introduction
Printer features Your printer is a high speed and rugged design for easy use and heavy
duty operation. It is designed for service-free PC, network and mini system operations.
At top speeds of up to 500 cps the LA550N and LA550 keep pace with
the bustling, demanding world where printing is time sensitive and critical. Engineered for printing under adverse conditions, these devices
produce multi-part invoices, shipping documents or bar code labels at
a rate of up to 26,000 pages per month.
The printer handles up to 5-part forms with no skewing or jamming; it
automatically adjusts for different forms thickness. The straight paper
path is easy to access, for reliable forms handling.
The LA550N/LA550W optionally is configured with an optional tractor
(front). A straight paper path on the front tractors results in jam-free
operation and flawless 24-wire impressions on up to 5-part forms. Both
models offer fully automated gap adjustment, paper parking, loading,
etc.
With extensive connectivity alternatives and popular emulations, the
printer is ideal for a variety of industrial or business applications.
Symbols used Important information is highlighted in this manual by two symbols.
CAUTION highlights information which must be observed in order to

Place your printer on a solid surface (see Placing
your printer, page 7).
Make sure that the “Up” symbols point in the correct direction.
Open the packaging, take out the accessory cassette and unpack it. 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 (c)
the Quick start guide (d), the power cable (e), the

Placing your printer
Place the printer on a solid, flat, surface, ensuring
that the printer is positioned in such a way that it
can not topple, and that there is easy access to the
control panel and paper input devices. Also ensure that there is sufficient space for the printed
output.
If you expect that frequent forward and reverse
feeds will occur, you should place the printer as
shown in the figure, if possible.
STOP
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.
When selecting the printer location, observe the
following additional instructions:
STOP
Never place the printer in the vicinity of
inflammable gas or explosive substances.
Do not expose the printer to direct sunlight. If you cannot avo id 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 Interface specifications
,
page 112).
Ensure sufficient distance between the printer and any heating radiators.

STOP
Make sure that the device has been set to the correct voltage (e.g.
120 V in the USA, 230 V in Europe). 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 place the printer on its back side.

User guide Changing the ribbon cassette

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.
Cautiously slide the print head carriage to the left
stop (viewed from the printer front).
STOP
The print head heats up during printing. Let it cool down before touching, if
necessary.
11
User guide Changing the ribbon cassette
Raise the printer bar cover.
Remove the used cassette.
We recommend use of genuine ribbon
cassettes only.
Turn the coloured ribbon feed knob at the right of
the new ribbon cassette in the direction of the arrow in order to take up slack of the ribbon.
12
User guide Changing the ribbon cassette
Slightly tilt the ribbon cassette forwards in such a
way that it is parallel to the housing top and thread
in the ribbon in front of the print head.
Locate the two projections in the left and right
guide rails of the printer and gently press down on
both sides until it clicks into place. In this way, the
cartridge is automatically positioned correctly.
Use the knob on the right side of the cassette to
take up slack of the ribbon again. Thereby the ribbon will slide over the plastic noses on the left and
right of the print head into the correct positon.
Press the printer bar cover down until it clicks into
place, remount the top cover, making sure that the
projections on the cover are inserted correctly into
the recesses of the printer housing, and close it.

Mode) (page 86).
The printer drivers either support the printer font Draft or Draft
Copy, not both. Selection, which kind of draft font is used, has
to be made in the printers menu mode (see Selecting font (Font)
page 49). If you want to switch between print qualities NLQ
(Near Letter Quality) and LQ (Letter Quality), you also have to
make this selection in menu mode.
,
Other operating systems
The printer can also be used with other operating systems such as
Linux or Unix. In this case, set the printer to the Epson emulation or
IBM emulation for which default drivers are available in most operating systems.

The control p anel
The control panel keys are used for controlling your work with the
printer. The control panel is located on the front right 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 (display message: Ready) is the printer’s normal
operating mode. Data from your computer can be received and printed.
` In the Offline mode (display message: Pause) the link between prin-
ter 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 (for
example adjustments, character density, font, paper path, adjustments i.e. head gap) directly without having to enter them via the
menu. The settings for the parameters character density and font
are lost when the printer is switched off. They can be selected permanently in the menu mode of the printer.
` In the Menu mode further printer settings (line spacing, size of the
interface buffer etc.) can be altered and saved permanently.
