Unit 1: Introduction

GENERAL DESCRIPTION

The SATO Lt408, OEM print engine has been designed and manufactured to meet the needs of the entry-level
print apply market. The entry-level market can be generally defined as small to mid-sized manufacturers with low
throughput, light-duty applications. These applications do not require the feature set found on standard OEM print
engines that usually make capital investment unjustifiable. The Lt408 offers this market the opportunity to
automate the labeling function with a system specified for their requirements and priced within their reach.

The Lt408 follows the SATO OEM print engine concept. The print engine, when integrated with an applicator
system provides low-throughput, light-duty applications with automated, yet affordable, print/apply labeling
solutions. Because the OEM print engine is a single-piece module, it can be easily and quickly removed for off-line
servicing or for complete module replacement. Like all SATO OEM print engines, the Lt408 includes an applicator
interface port to provide the required synchronization and messaging between the printer and the applicator.

When specified for suitable applications, the SATO Lt408 print engine is designed to provide years of reliable
labeling operations.

Unit 3: Installation

MEDIA SELECTION

The size and type of labels to be printed should have been taken into consideration before printer purchase.
Ideally, the media width will be equal to, or just narrower than, the print head. Using media that does not cover the
print head will allow the platen roller to tread upon its surface resulting in premature wear. The media edge will also
wear a groove in the platen roller affecting print quality.

There are two types of media that may be used: thermal transfer and direct thermal. Thermal transfer media
requires the use of ribbon stock for print application. In such a scenario, it is the ribbon stock (carbon paper) that
contains the ink that will be transfered to the media.

Direct thermal media has thermally reactive material embedded within and is brought to the surface through heat
penetration by print head contact. Only load ribbon stock into the printer if that media type is to be used.

RIBBON LOADING

To load ribbon stock, unlatch the print head and remove exhausted ribbon stock if applicable. Insert an unused
ribbon roll, with ribbon core, fully onto the ribbon supply boss (left) and an empty core onto the ribbon rewind boss
(right). Route the ribbon’s free end around the print assembly and tape it to the blank core on the rewind boss.
Rotate the core a couple of times while holding the boss stationary to take up take up slack. Refer to Figure 3-5 for
visual assistance.

WARNING: AVOID PHYSICAL CONTACT WITH THE PRINT HEAD TO PREVENT
BURNED FINGERS/HANDS AND COMPONENT DAMAGE.

NOTE: Properly installed ribbon stock will be oriented so that its dull, ink side is facing
the printer chassis while the ribbon is dispensed and taken up on the right side of
each roll. The non-ink side of the riibon stock is the shiniest of the two surfaces.

MEDIA LOADING

To load label media, unlatch the print head and remove any remnants that may exist of the prior media supply.
Feed the free end of the media from the printer’s left side, beneath the shaft of the media guide, between the upper
and lower halves of the label sensor, across the top of all forthcoming rollers, and through to protrude six or more
inches beyond the printer chassis.

Ensure the media is flush against the printer’s back side (toward the center wall) and then adjust the media guide
inward until it almost makes contact with the media’s backing paper.

Remove all labels from the backing paper that extend beyond the printer chassis and relatch the print head.

Lift upward on the pressure roller release knob (purple) and allow the pressure roller plate to fall to a vertical
position. Route the backing paper’s free end around the front of the printer chassis, beneath the front platen roller
and onward between the second platen roller and the pressure roller. Pull the free end of the backing paper to
remove all slack while lifting the pressure plate until latched. Refer to Figures 3-5 and 3-6 for visual assistance.

WARNING: AVOID PHYSICAL CONTACT WITH THE PRINT HEAD TO PREVENT
BURNED FINGERS AND HANDS.

NOTE: Properly installed label media will be oriented so that the label side is upward
and the backing paper is downward resting upon the printer chassis.

NOTE: Refer to the Printer Configuration unit of this manual for media configuration
instructions and the Adjustment chapter of the Maintenance unit for label sensor
adjustment instructions as necessary.

OPERATIONAL MODE SELECTION

There are two modes of printer operation: Dispense or Continuous. The difference between the two is the way that
the label and paper backing is ejected. Before printer configuration, one must determine which mode will be used.
This chapter identifies and defines the functional differences between the two.

DISPENSE MODE

With this method of operation, after printing, the printer feeds the first (outermost) label so that it is fully extended
out of the printer’s front for dispensing. Printing of the next label will not begin until the prior printed label has been
removed. This mode of operation is specifically suited for the use of automated machinery to remove the printed
and dispensed label to apply to packaging, etc.

Upon removal of the prior printed label, the printer repositions the media so that the next label in line may be
printed, then prints. The before-mentioned cycle, repeats for each consecutive label.

Printer configuration for the backfeed function may be found in the Advanced Mode of the Configuration unit of this
manual. Refer to the Table of Contents for the page number.

CONTINUOUS MODE

With this method of operation, the media remains in position for printing at all times. To do so, means that the
previous printed label is never in proper position for dispensing and thusly, must be manually removed form the
printer rather than through the application of automated machinery.

Printer configuration for Continuous mode of operation may be found in the Advanced Mode of the Configuration
unit of this manual. Refer to the Table of Contents for the page number.

ATTENTION: Refer to the Printer Configuration unit of this manual to program the
printer’s internal memory to suit individual needs using the printer’s integrated menu
options. Refer to the Programming Reference document to remotely program the
printer’s features and functions through a host system.

INTERFACE SELECTION

This unit presents the printer interface types and their specifications. These specifications include detailed
information to assist in the selection of the most appropriate method for the printer to interface with the host. The
five acceptable interface methods are:

• RS232C High-Speed Serial

• IEEE1284 Parallel

• Universal Serial Bus (USB)

• Local Area network (LAN) Ethernet

• 802.11b Wireless

Following the selection of the desired interface, proceed to the next unit for instructions on how to Configure the
printer for that interface type.

WARNING: NEVER CONNECT OR DISCONNECT INTERFACE CABLES (OR USE
A SWITCH BOX) WITH POWER APPLIED TO EITHER THE HOST OR THE
PRINTER. THIS MAY CAUSE DAMAGE TO THE INTERFACE CIRCUITRY IN THE
PRINTER/HOST AND IS NOT COVERED BY WARRANTY.

NOTE: Some hosts monitor the Request-To-Send (RTS) signal (pin 4 of 25) to
determine if the printer is ready to receive data. Since the printer does not generate
this signal, the RTS line must be held true (high) in order to allow communication. This
can be performed by connecting the RTS pin to the Clear-To-Send (CTS) signal (pin 5
of 25).

READY/BUSY INTERFACE SIGNALS

PIN DIRECTION SIGNAL DEFINITION

1 Reference FG (Frame Ground)

2 To Host TD (Transmit Data) - Data from the printer to the host computer. Sends X-On/X-Off characters

or status data (bi-directional protocols).

3 To Printer RD (Receive Data) - Data to the printer from the host computer.

4 To Host RTS (Request to Send) - Used with Ready/Busy flow control to indicate an error condition.

RTS is high and remains high unless the print head is open (in this case, RTS would return to
the high state after the print head is closed and the printer is placed back on-line) or an error
condition occurs during printing (e.g., ribbon out, label out).

5 To Printer CTS (Clear to Send) - When this line is high, the printer assumes that data is ready to be

transmitted. The printer will not receive data when this line is low. If this line is not being used,
it should be tied high (to pin 4).

6 To Printer DSR (Data Set Ready) - When this line is high, the printer will be ready to receive data. This

line must be high before data is transmitted. If this line is not being used, it should be tied high
(to pin 20).

7 Reference SG (Signal Ground)

20 To Host DTR (Data Terminally Ready) - This signal applies to Ready/Busy flow control. The printer is

ready to receive data when this pin is high. It goes low when the printer is off-line, either
manually or due to an error condition, and while printing in the single job buffer mode. It will
also go low when the data in the buffer reaches the buffer near full level.

* This connection at the host side of the interface would depend upon the pin that is being used as the Ready/Busy signal by
the driving software. Typically, on a PC, it would be either CTS (pin5) or DSR (pin 6) on a DB-25 connector.

X-ON/X-OFF CABLE REQUIREMENTS

Communicates with the host to determine if the printer is ready to receive data by sending “XON” (HEX 11H) or “XOFF” (HEX
13H) code to the TD line. The single and multiple item buffers are switchable in the Interface Mode of the printer.

Unit 3: Installation

IEEE1284 PARALLEL INTERFACE

The parallel interface is a plug-in module that can be installed by the user and conforms to IEEE1284
specifications. It automatically detects the IEEE1284 signals and operates in the high speed mode. If the
IEEE1284 signals are not detected, it will operate in the slower standard Centronics mode. For this reason, an
interface cable and host interface conforming to the IEEE1284 specification must be present to fully utilize the

ALL INTERFACES

RECEIVE BUFFER

The data stream is received from the host to the printer one job at a time. This allows the software program to
maintain control of the job print queue so that it can move a high priority job in front of ones of lesser importance.
A multiple job buffer allows the printer to continuously receive print jobs while compiling and printing other jobs at
the same time. It acts much like a Print buffer to maximize the performance of the host and the printer.

The printer receives and prints one job at a time. If a print job exceeds the buffer size, transmission will be rejected
by the printer. Flow control protocols to throttle transmission are not used. Error conditions that occur during the
Print Data transmission will cause the printer to return a NAK.

ACK/NAK PROTOCOL

Bi-Directional ACK/NAK protocol is used for error control. In a normal transmission sequence when the
transmission is received, the printer will return an ACK (06H) signifying that it was received without a transmission
error. After the transmission command structure has been analyzed, a status byte is returned to the host. This
status byte informs the host of the validity of the command structure.
If the command structure is error free, the printer proceeds with the print operation. When the print operation is
completed, a Printer Status message is returned to the host. If an error was detected during the initial transmission
sequence, a NAK (15H) will be returned signalling to the host that the received transmission contained errors and
must be resent. If the returned Status byte indicates a command structure error, the error must then be corrected
before the print data is resent to the printer.
A valid transmission to the printer must be bounded by an STX/ETX pair, with the STX (02H) signifying the start of
the Print Data and ending with an ETX (03H) signifying the end.

STATUS5 RETURN

This communication protocol is designed for the purpose of monitoring and controlling print data status in the host
and featuring various functions.

Entry is not required for this screen. The values will change as the potentiometers are
adjusted.

Permits the printer’s print speed to be established based on inches per second (IPS).

Permits the adjustment of the print density. Higher print density equates to darker print
images.

The label pitch is the distance from the leading edge (the edge that comes out of the
printer first) of a label and the leading edge of the next label. The position of the label’s
leading edge can be adjusted relative to the print head in increments of 1mm. Once the
position has been set, it can be fine adjusted using the PITCH potentiometer.

Positive (+) digit selection on the display moves the leading edge forward and away
from the print head while a negative (-) selection moves the label’s leading edge
incrementally back into the mechanism.

INTERFACE TROUBLESHOOTING

This chapter provides a checklist for the various interface types. Locate the checklist relative to the interface used
and perform each of the troubleshooting tasks until the problem has been isolated.

PARALLEL INTERFACE

CHK TROUBLESHOOTING STEP

Ensure the interface module is correctly installed. Run self-test to verify.

Ensure the printer cable is connected to the appropriate LPT port on the host computer. If using a Windows printer
driver, ensure the correct port is selected.

Ensure a IEEE1284 printer cable is being used.

Ensure the host’s peripheral settings are set to ECP for faster throughput. Refer to the computer manufacturer’s
documentation for details.

Ensure the printer is receiving information from the computer using the Receive Buffer Hex Dump mode. Refer to that
procedure within this manual for instructions. The command stream should be continuous and possess 0Dhex and/or
0Ahex (carriage return and line feed) characters throughout. However, there should not be either located between the
start (<ESC>A and the stop (<ESC>Z) commands.

Replace the interface board with another to isolate the problem.

Replace the interface board permanently if determined to be the problem.

RS232 SERIAL INTERFACE

CHK TROUBLESHOOTING STEP

Ensure the correct interface module is correctly installed. Run self-test to verify.

Ensure the serial cable (Null Modem) meets specifications and is correctly connected at each end.

Ensure the serial cable is not defective.

Ensure the communication parameters for the baud rate, parity, data bits and stop bits are consistent with those being
sent from the host computer.

Ensure the printer is receiving information from the computer using the Receive Buffer Hex Dump mode. Refer to that
procedure within this manual for instructions. The command stream should be continuous and possess 0Dhex and/or
0Ahex (carriage return and line feed) characters throughout. However, there should not be either located between the
start (<ESC>A and the stop (<ESC>Z) commands.

Replace the interface board with another to isolate the problem.

Replace the interface board permanently if determined to be the problem.

UNIVERSAL SERIAL BUS (USB) INTERFACE

If nothing prints during a test print, verify the device drivers have been successively installed by performing the following:

Click on Start, Settings, and then Control Panel.

Click on System within the new window.

Click on the Device Manager tab.

Ensure that the View Device By Type is checked.

Scroll to SATO-USB Device and ensure that errors do not exist. Reinstall as required.

Reboot the PC and the printer.

Contact Microsoft technical support for further assistance as required.

Lt408 Operator Manual

5-8 PN: 9001152A

Unit 5: Troubleshooting

LAN ETHERNET INTERFACE

CHK TROUBLESHOOTING STEP

Ensure the interface has been correctly configured. Wait two minutes and run self-test to verify. If a test label does not
print, there may be a hardware problem.

Ensure the cable and its ports are not defective.

Ensure that a faulty print server or other protocol related scenarios are not creating a queue setup issue.
Systematically perform checks and tests to isolate the cause.

If using TCP/IP, ensure a valid IP address is specified and that all parameters are correct (subnet mask, gateway,
etc.). Attempt to PING the IP address assigned to the network interface.

If using a repeater or hub, ensure the SQE is turned off. Also ensure the repeater port is not defective by trying the
print server on another port.

Install the IPX/SPX protocol on a workstation to determine if the network device can be discovered via the MAC
address. If able, configure the appropriate protocols and retest connectivity.

Use a crossover cable to isolate the printer from the network by connecting from the interface and workstation. Verify
that the parameters match on each. Test connectivity.

WIRELESS LAN INTERFACE

CHK TROUBLESHOOTING STEP

Ensure the interface module is correctly installed. Run self-test to verify.

Check the signal strength by the three LED’s on the interface. The more LED’s are illuminated green, the stronger the
signal.

Ensure the printer is receiving information from the computer using the Receive Buffer Hex Dump mode. Refer to that
procedure within this manual for instructions. The command stream should be continuous and possess 0Dhex and/or
0Ahex (carriage return and line feed) characters throughout. However, there should not be either located between the
start (<ESC>A and the stop (<ESC>Z) commands.

Ensure the interface has been correctly configured. Wait two minutes and run self-test to verify. If a test label does not
print, there may be a hardware problem.

If using TCP/IP, ensure a valid IP address is specified and that all parameters are correct (subnet mask, gateway,
etc.). Attempt to PING the IP address assigned to the network interface. Also ensure the SSID, channel, and security
matches that of the network.

Install the IPX/SPX protocol on a workstation to determine if the network device can be discovered via the MAC
address. If able, configure the appropriate protocols and retest connectivity.

Replace the interface board with another to isolate the problem.

Replace the interface board permanently if determined to be the problem. Also reset the interface card.

CENTRONICS INTERFACE

CHK TROUBLESHOOTING STEP

Ensure the interface module is correctly installed. Run self-test to verify.

Ensure the printer cable is connected to the appropriate LPT port on the host computer. If using a Windows printer
driver, ensure the correct port is selected.

Ensure the host’s peripheral settings are set for Centronics output for faster throughput. Refer to the computer
manufacturer’s documentation for details.

Ensure the printer is receiving information from the computer using the Receive Buffer Hex Dump mode. Refer to that
procedure within this manual for instructions. The command stream should be continuous and possess 0Dhex and/or
0Ahex (carriage return and line feed) characters throughout. However, there should not be either located between the
start (<ESC>A and the stop (<ESC>Z) commands.

Replace the interface board with another to isolate the problem - permanently replace if defective.

CLEANING PROCEDURES

Cleaning of the printer is a necessary maintenace activity to ensure print quality and longer printer life. There are
two basic types of cleaning involved; the removal of loose debris and the removal of residue.

Use a soft cloth and/or a pneumatic blower to remove debris from the printer. This process should be performed
prior to the removal of residue. To remove residue, apply SATO Solvent or isopropyl alcohol to a clean cotton swab
and gently wipe the entire surface of the print head and rollers until clean.

To gain access to the printer’s chassis, pull purple knob (1) outward to drop plate (2) downward. Remove thumb­screw (3) should removal of the plate become necessary.

WARNING: DISCONNECT POWER SUPPLY TO THE PRINTER AND ALLOW TO
COOL TO ROOM TEMPERATURE PRIOR TO CLEANING. EXCERCISE CARE
WHEN CLEANING TO PREVENT PERSONAL INJURY.

CAUTION: IF USING A PNEMATIC BLOWER TO REMOVE DEBRIS FROM THE

PRINTER, EXCERCISE CARE TO PREVENT PRINT HEAD DAMAGE.

REPLACEMENT PROCEDURES

This unit provides in-depth instruction on all primary component and assembly replacement, in addition to most
secondary components. Use the text in conjunction with their accompanied graphics to ensure complete
comprehension throughout the process. Especially observe all cautionary or warning notations.

FUSE REPLACEMENT

Fuse access may be gained externally without having to remove covers, etc. The fuse is located on the printer’s
underside adjacent to the power supply cord connector. To inspect or replace the fuse, simply twist off the cap and
the fuse will exist with it.

PRINT HEAD REPLACEMENT

If the print head becomes damaged or worn, it can be easily removed and replaced without having to make critical
adjustments. Before replacing the print head, check the head counter values by printing a test pattern. Instructions
relating to the Head Counter may be found in the Configuration unit of this manual.

1. Switch off the printer and observe applicable lockout-tagout procedures.

2. Open the front cover and the print head release lever.

3. Pull outward on print head release knob (1, Figure 6-2) to release defective print head (2) from print
assembly (3). Disconnect the two wiring harnesses.

4. Reconnect two wiring harnesses (not shown) to replacement print head (2).

NOTE: Each of the printer’s wiring harness connectors are different from all others to
ensure proper mating. Mate each matching half for reconnection.

5. Pull and hold outward on release knob (1) while applying replacement print head (2) to print assembly (3).

CAUTION: THE BRACKETS ON EACH END OF THE PRINT HEAD MUST SNAP
INTO POSITION ON THE RELEASE KNOB’S SHAFT. ENSURE THE PRINT HEAD
IS SECURELY AND PROPERLY INSTALLED PRIOR TO OPERATING THE
PRINTER TO PREVENT MECHANICAL DAMAGE.

6. Restore power, reset the head counter, and test print.

ROLLER REPLACEMENT

The printer’s three rubber rollers are considered to be high-wear components due to constant treading of the print
media and ribbon stock against their contact surfaces. This constant contact will eventually wear grooves into the
rubber material and negatively effect print output.

The procedure below applies for all three rubber rollers. However, some rollers do not incorporate the use of
spacer (5) so in those cases, that process is to be ignored.

1. Switch off the printer and observe appropriate lockout-tagout procedures.

2. Loosen screw (1, Figure 6-3) sufficiently to rotate bearing clamp (2) from bearing (3).

NOTE: Figure 6-** shows screw (1) and bearing clamp (2) as being removed for
display purposes only. It is not necessary to remove those components for roller
replacment.

3. Withdraw bearing (3) from chassis (4) and spacer (5) from defective roller (6) consecutively.

NOTE: Ignore removal of spacer (5) if that component is not present on the roller
being replaced.

4. Withdraw defective roller (6) from chassis (4) and insert replacement roller (6) in its place.

NOTE: To remove the roller, move it toward its free end and then lift upward.

5. Insert spacer (5) onto the free end of replacement roller (6) followed by bearing (3).

6. Rotate bearing clamp (2) onto bearing (3) and secure using screw (1).

7. Repeat steps 2 through 6 for all other roller assemblies that require replacement.

8. Restore power and test print.

ADJUSTMENT PROCEDURES

This unit covers all of the printer and printer accessory adjustments. These adjustments include mechanical
adjustments required following the replacement of components and assemblies, in addition to, the operational
adjustments required following a job change.

PRINT HEAD ALIGNMENT

Print head position has a direct impact on print quality. The print head must be parallel with the platen roller for the
printed image to be consistent across the label.

To adjust the alignment, test print a label, loosen the set screw, slightly move the adjustment plate to the right or
left as deemed necessary to align the print head with the roller, and reprint a label. Repeat the process until proper
printing is achieved and then retighten the set screw while holding the adjustment plate in position.

CAUTION: THE PURPLE KNOB HASN’T ANYTHING TO DO WITH PRINT HEAD
ALIGNMENT. PULLING ON THIS KNOB WILL RELEASE THE PRINT HEAD.

PRINT HEAD BALANCE ADJUSTMENT

Print head balance is the equalization of pressure against the platen roller from one end to the opposite. If the print
head balance is out of adjustment, the printed image will be darker on one side of the label than the other and the
media will be prone to travel in the direction of least resistance.

The adjustment of print head balance on the label can be subjective. One will know when balance is achieved by
the disappearance of prevailing negative print characteristics.

To adjust the balance, begin test printing, slightly loosen the set screw, and slightly move the adjustment plate to
the right or left as necessary. Retighten the set screw while holding the adjustment plate when proper printing is
achieved.

RIBBON GUIDE ADJUSTMENT

If the print ribbon is not spread smoothly over the print head when it makes contact with the media, print voids will
occur at the point of the ribbon fold. Typically, this is the result of the axis of one of the following not being perfectly
parallel: ribbon spindle, ribbon roller, print head, or ribbon guide.

The purpose of the adjustable ribbon guide is to compensate for the axis deviations of the other three. By adjusting
the ribbon guide proportionally to the degree of deviation, the ribbon spreads smoothly as it travels from the ribbon
supply spindle, to the guide, and beyond.

Ribbon guide adjustment is a trial and error activity that requires the pause of printing, unlatching of the print head,
adjusting the guide, relatching the print head, and printing once again. Several labels must be printed following
each adjustment to determine if the adjustment was effective.

The ribbon guide is secured to the face of the print assembly by a screw on each end. Before adjusting the guide,
visually inspect that its axis is parallel with that of the print assembly. If not, adjust accordingly, ensure the set
screws are secure, and once again commence printing.

By starting in a neutral position, either end may be adjusted vertically as necessary to remedy the wrinkling
problem.

LABEL SENSOR POSITIONING

The label sensor assembly provides a mounting apparatus for the eye-mark, gap, and paper-end sensors. Position
adjustment of the label sensor is not required when using standard label media.

When non-standard media is used, place a section of the media on the media ramp oriented as if loaded for
printing. Manually grasp the sensor assembly and move it laterally so that the sensor indicators embossed in its
side are aligned with the reference marks on the media.

Sensor positioning may also be achieved by measuring from the printer’s center frame outward to a specified
distance for sensor/reference mark alignment.

OPERATIONAL ADJUSTMENTS

These operational adjustments are for fine tuning the printer as necessary following the configuration process and
are largely confined to the four potentiometers located on the operator panel. Refer to the table below for their
function.

POTENTIOMETER DESCRIPTION/PROCEDURE

VOLUME Adjusts the audible decimal level for error indication. Power on the printer, place

on-line, and open the print head. When the beep is emitted, adjust the volume
level accordingly.

PITCH Is to be used in conjunction with the configuration adjustments. Make course

adjustments there and then fine tune here. If unable to achieve the desired
setting here, the course adjustment must be reset. Adjust this potentiometer as
labels are being printed. Allow two labels to be printed for each adjustment to
ensure a desired setting.

Adjustment of the PITCH potentiometer will affect the print offset position.

OFFSET The offset adjustment is used to reposition the media for printing following

advancement for dispensing. A label is printed, it is fed forward for dispense, the
printer retracts the remaining media (offset) to print the next label. To perform
this adjustment:

1. Power On the printer.

2. Press the LINE key to place printer offline.

3. Advance to the User Mode and press ENTER.

4. Adjust the OFFSET potentiometer.

5. Press the FEED key to feed another label.

6. Repeat steps 3 and 4 until properly adjusted.

7. Press the LINE key to bring the printer back online.

DARKNESS Is used to adjust the darkness or lightness of the printed image and should be

used in conjunction with the configuration adjustments. Make course
adjustments there and then fine tune here. If unable to achieve the desired
setting here, the course adjustment must be reset.

Adjust this potentiometer as labels are being printed. Allow two labels to be
printed for each adjustment to ensure a desired setting.
