GENERAL PRECAUTIONS
• Head cleaning liquid (if supplied) is flammable. Never
heat it or throw it into a fire. Keep it out of children’s
reach to avoid accidental consumption. Should this
occur, consult a doctor immediately.
• When opening/closing the cover, beware of getting
your fingers caught. Also, hold the opening/closing
cover well so that it will not slip and fall on your hand.
• After printing, the print head remains hot. When
replacing paper or cleaning the printer immediately
after printing, be careful not to burn yourself.
• Touching even the edge of the printer head may
cause injuries. When replacing paper or cleaning the
printer, be careful not to hurt yourself.
• If the printer will not be used for extended periods of
time, disconnect the power cable for safety.
• When releasing and locking down the printer head,
be careful not to catch any other foreign matter in it
except label paper.
• Do not disassemble or perform modifications to
the printer, as this renders the product unsafe.
For maintenance, troubleshooting and repairs,
consult a sales outlet, dealer, or service center
for help, instead of attempting to perform this
yourself. Renewable annual service contracts
are available.
• When maintaining or cleaning the printer,
always disconnect the power cable for safety.
• Do not insert your hand or other objects into the
cutter.
• When loading roll paper, be careful not to catch
your fingers between the paper and the feeder.
• Be careful not to hurt yourself when detaching
the back cover of the fanfold through the hole
and attaching it.
• The simplified cutter (where installed) is structured as a blade. Be careful not to cut yourself.

About the Head Check function
• The head check function detects the integrity of the heating elements in the thermal
print head. However, malfunctions cannot be detected instantaneously—a few
printed labels may start showing printing defects before the printer warns of a print
head error.
• After detection of a print head error, use a scanner to check all affected labels.
• When a head check error occurs during normal printing (barcodes, text and graphics), press and hold down the FEED button for five seconds. At the next screen,
select NORMAL and then press and hold down the LINE and FEED buttons for five
seconds to cause printing to resume. If the head check error occurs again, set the
type of head check to BARCODE and see if printing can be resumed normally.
• Although restricting the head check type to BARCODE allows you to continue printing, you should only do so in order to complete an urgent print job. Check the
printed labels to make sure the output is usable in spite of the head error. As soon
as possible, stop using the print head to prevent further damage. If necessary, get
the print head replaced.

3.12 UNDERSTANDING DISPENSER AND CONTINUOUS PRINT OPERATION
Two modes — Dispenser and Continuous Print operation — are available for use in the Lt408
print engine. The difference between the two operations is in the way the label paper is ejected.
Here are the details:
Dispenser Operation (Default)
In this method of operation, after printing,
the printer feeds the first (outermost) label
so that its bottom edge rests at the position
of the dispenser area. This label can then
removed. Printing does not resume until
this label is removed.
Dispenser Operation
The label behind the dispensed label is
now the first label. Its position has gone
beyond the print head. Therefore, a
backfeed is performed (optional). When the
label is in position, printing begins.
It is then dispensed and printing stops
while the printer waits for the dispensed
label to be removed. The option to set
Backfeed is in the Advanced Mode>Backfeed Motion menu (See page 3-13) .
You can disable the Backfeed or set it to occur BEFORE or AFTER print.
Continuous Print Operation
In this method of operation, whenever a
print job has been completed (or when a
sheet of paper is fed) the paper is ejected
outwards until the second label from the
front is placed just in front of the print head.
The first label will not be completely
ejected, and cannot be torn off neatly.

CLEANING AND MAINTENANCE
4.1 INTRODUCTION
4
This section provides information on user maintenance for the Lt printe engine. The
following information is covered here:
• Cleaning the Print Head, Platen and Rollers
• Adjusting print quality
4.2 CLEANING THE PRINT HEAD, PLATEN AND ROLLERS
The print head not only generates printouts of barcodes, but also graphics and text. To produce
optimal printing, it must be kept clean in spite of the dirt and adhesive that constantly
accumulates on its print surface. Furthermore, dirt can accumulated along the label path,
affecting parts like sensors and guides, and reducing their performance.
Therefore, it is important to clean these important components periodically. Depending on the
region you are in, the Lt print engine may already come supplied with a cleaning kit or set of
cleaning sheets. If any of the cleaning items need replacement, contact your authorized SATO
dealer.
When to clean with a cleaning kit
♦ For the print head, platen roller, paper sensor, and label guide: clean after using up every other
roll of paper, or each time after printing 150 m.
♦ For other parts: clean after finishing every six rolls of paper, or every time after printing 900 m.
When to clean with the cleaning sheet
♦ For the print head, platen roller: clean after using every six rolls of paper, or every time after
printing 900 m.

4.4 HOW TO CLEAN THE PRINTER (CLEANING SHEET)
The cleaning sheet is used for cleaning the print head and platen roller.
1. Lift up the front cover.
2. Unlatch the print head unit using the purple Head
Lock lever and head release latch.
The print head is now accessible.
3. Remove the label and ribbon.
4. Put the head cleaning sheet between the print head
and the platen roller. The coarse side of the cleaning
sheet should face the surface of the print head elements.
5. Fasten the Head Lock lever to mount the print head.
6. Using both hands, pull the cleaning sheet outwards, toward your body. This will
remove any dirt stuck to the print head. (See generic figure on the right)
7. When the cleaning sheet has been removed, perform steps 2 to 6 to repeat the cleaning procedure one or two more times.
8. When no more additional dirt appears on the cleaning sheet after it has been pulled
out, you can stop cleaning with the sheet.
9. Unlatch the print head and use the cleaning cloth from the cleaning kit to gently
remove any remaining dirt from the print head.
Caution
• Be sure to turn off the power before cleaning.
• The suggested cleaning schedule here are just guidelines. If necessary, clean as appropriate depending
on the degree of contamination.
• Use a cleaning pen or cotton cloth to clean the printer units.
• Use only soft, lint-free materials for cleaning. Avoid using hard objects for the cleaning process, as they
will damage the components.

4.5 ADJUSTING PRINT QUALITY
Print quality can be optimized with regular cleaning and maintenance of the print head and
components along the label path. Additionally, you can fine-tune print quality by adjusting print
darkness and print speed settings.
4.5.1 Adjusting Print Darkness
This adjustment allows the user to control (within a specified range) the amount of power applied
to the individual print head heat elements. It is important to find a proper print darkness level
based on your particular label and ribbon combination. The printed images should not be too light
nor should the ink from the ribbon “bleed.” The edges of each image should be crisp and well
defined.
LCD Panel — The Print Darkness can be set from the configuration
panel or by sending the Print Darkness software command from a
computer. There are five settings, from 1 (lightest) to 5 (darkest).
The default setting is 3.
Once the range has been selected, the Darkness Potentiometer on
the front panel can be used to make finer adjustments. For
instructions on setting Print Darkness, refer to Section 3,
Configuration.
Darkness Potentiometer — The fine
adjustment for Print Darkness is the
Darkness Potentiometer hidden behind
the front panel. It provides a continuous
FEED
range of adjustment, allowing you to
make precise changes. Use a small
cross-point screwdriver, turning
loudness
clockwise for darker print and
counterclockwise for lighter print. See
Section 3: Configuration for
instructions on performing potentiometer adjustments.

darkness
Note
The PRINT potentiometer adjustment will affect the darkness in all of the command code speed
ranges, i.e., if the PRINT potentiometer is adjusted for lighter print, the darkness will be lighter in
all speed ranges selected by the command code.

5.10 X-ON/X-OFF
This transmission protocol informs the host if the print engine can receive data or not, by sending
the "XON" (Hex 11H) or "XOFF" (Hex 13H) code.
Data received cannot be guaranteed, when print data (ESC+"A"~ESC+"Z") is sent from the host,
under the following conditions:
1) When the print engine is Offline
2) When an error has occurred in the print engine

A low level pulse signal will be output when data
scanning is complete to inform the host.
“High” will be maintained when the Reception buffer
has reached full or when an error occurs in the printer,
and “Low” will be output when the printer is ready to
receive.
The level will become “High” when labels have run out
and none have been set.
The signal will be in “High” level when reception is
possible, otherwise it will be “Low” level.

TROUBLESHOOTING
If you are unable to produce printouts on the LT Series print engine,
use this section to make sure the basics have been checked, before
deciding you are unable to proceed any further. The section is divided
into seven parts:

Observations
Initial Checklist
Checklist for the Centronics Parallel Interface
Checklist for the RS232C Serial Interface
Understanding ON LINE, RIBBON, LABEL indicators
Understanding the LCD error messages
Understanding the LCD warning messages
General Troubleshooting Guide
6.1 INITIAL CHECKLIST
1. Is the print engine powered up and ON LINE?
2. Is the ERROR light on the front panel OFF? If this light
is ON, it may mean the print head assembly is open or
another error condition is present.
3. Are the Label Hold-Down and Print Head Assembly in
the latched position?
6.2 USING THE CENTRONICS (PARALLEL) INTERFACE
1. Is the IBM parallel printer cable connected securely to
your parallel port (DB-25S Female) on the PC and to
the parallel port on the print engine?
2. Is there more than one parallel interface port on your
PC (LPT1, LPT2, etc.)? If so, make sure you are sending data out the correct port.
3. When you send the print job to the print engine, and it
does not respond, do you get an error message on
your PC that says “Device Fault” or something similar?
This may mean that the computer doesn’t know the
print engine is there. Verify that:
a. Both ends of the cable are securely inserted into
their respective connectors.
b The print engine is ONLINE.
c. The cable is not defective. There are other things
that can cause this error message on your computer, but at this stage, a defective cable may be
one of the reasons.
Lt408 Operator’s Manual
Page 6-1
Section 6: Troubleshooting
6.2 USING THE CENTRONICS (PARALLEL) INTERFACE (CONT’D)
4. When you send the print job to the print engine and
it does not respond, and there is no error message
on the PC:
A. Check your data stream for some of the basics.
Is your job framed as follows?
<ESC>A—DATA—<ESC>Z
B. Verify that you’ve included all required parameters in the data stream.
C. Verify the following:
• You have not typed a “0” (zero) for an “O”
(letter) or vice-versa.
• You have not missed any <ESC> characters
where they’re needed.
• Make sure all print engine command codes
are capital letters.
• Your protocol codes are set for Standard or
Non-Standard and your data stream is consistent with these.
Observations
5. If you’ve checked all of the above and the print engine still
isn’t printing, you may want to try a Receive Buffer Hex
Dump to determine what (if anything) the print engine is
receiving from your computer. To print Hex Dumps see
page 3-19, Configuration and Operation.
The parallel port is now listening for incoming data. Send
your print job. The print engine will now print (only once) a
Hexadecimal (Hex) Dump of everything it received from the
host computer. Each 2-digit hexadecimal character represents a character the print engine received. It may be
tedious, but now you can analyze and troubleshoot the data
stream.
6. While checking the Hex Dump printout, look out for the
sequence 0D 0A, which is a combination of Carriage Return
and Line Feed characters. The command string should be
continuous, and you should not see CR or LF characters
between the Start Command (<ESC>A ) and the Stop Command (<ESC>Z ).
If you are using BASIC, it may be adding these characters
automatically as the line wraps. Adding a “width” statement
to your program can help to suppress these extra 0D 0A
characters by expanding the line length up to 255 characters.
See the beginning of the Programming Reference, under
Command Codes, for details on writing a program in BASIC.
If you are not programming in BASIC, check to see if you
have an equivalent statement in the language you’re using,
to suppress extra carriage returns and line feeds from your
data being sent out to the print engine. The data stream
should be one complete line going to the print engine.
Page 6-2
Lt408 Operator’s Manual
Section 6: Troubleshooting
6.3 USING THE RS232C (SERIAL) INTERFACE
1. Is the RS232C Serial cable connected securely to
your serial port on the PC (DB- 25S Male) and to
the RS232C connector on the print engine?
Observations
2. Is the cable defective? At the very least, you should
be using a “Null Modem Cable,” which crosses pins
in a specific manner. This should enable your print
engine to print. But we recommend that you eventually use a cable built to specifications as described
in Section 5: Interface Specifications
3. Check for obvious errors in the data stream.
Remember that all print jobs for serial data must be
framed by an STX and ETX. Again, see the Section
5: Interface Specifications if necessary.
4. If after sending your job to the print engine, it only
“beeps” indicating a “framing error” message, you
may have a configuration problem. There may be
some inconsistencies with the Baud Rate, Parity,
Data Bits, or Stop Bits in relation to your host computer. If you are confused as to what the print
engine’s current RS232 settings are, you may
choose the SATO defaults (all DIP switches in the
OFF position) to achieve 9600 baud, no parity, 8
data bits, and 1 stop bit.
