Overview and Specifications
1.1 Overview
The SATO CT Series Printers Service Manual provides information for installing
and maintaining CT400/410 Direct Thermal/Thermal Transfer printers. Step-bystep maintenance instructions are included in this manual with typical problems
and solutions. It is recommended that you become familiar with each section in
this manual before installing and maintaining the printer.
The major differences in the CT400 and the CT410 printers is the resolution of
the head. The CT400 with its 203 dpi head provides an economical labeling
solution for most applications. It can print labels up to four inches wide. The
CT410's higher 305 dpi resolution provides greater detail for graphics and small
point size text.
The CT Series printers use a subset of the standard SATO Command Language.
The CT400 and CT410 share the same command set, the only differences are the
allowable values representing the print positions on the label. These values are
specified in "dots" and will vary depending upon the resolution of the printer
and the amount of memory available for imaging the label. The allowable range
for each printer is specified in a table for those command codes.
The sections in this manual cover the following:

1.8 Ribbon (Thermal Transfer Unit)
Use only SATO thermal transfer ribbons which were formulated expressly for use in all
SATO thermal transfer printers. Use of other than approved ribbons may result in
unsatisfactory print quality and/or damage to the print head and may void your warranty.
The SATO CT Series ribbons come shrink-wrapped with a 12" (305 mm) leader preattached to a take-up core. There are three widths of ribbon available for the CT Series
printers: 4.3" (110 mm), 3" (76 mm) and 1.75" (45 mm).
Refer to the illustrations on the following pages and load the ribbon as follows:
STEP
PROCEDURE
1.
Switch the printer OFF.
2.
Open the top cover by pressing on the cover release points located on each side
of the printer. This releases the cover latch and allows it to swing upward on
the rear mounted hinge points.
3.
Release the head by pressing the Head Latch to the rear. This allows the Ribbon
and Print Head Assembly to swing upward to the left allowing easy access for
ribbon routing. Swing the assembly until it is vertical.
4.
Press down on the Ribbon Assembly Latch. This allows the Paper Roller to
swing downward for ribbon routing.
5.
Press down on the Ribbon Positioning button while simultaneously pulling
outward on the Ribbon Spindle Unit. The Ribbon Spindle Unit should slide off.
6.
Remove the shrink wrap from the ribbon and press the core on one spindle of
the Ribbon Spindle Unit. Either spindle is OK because the Ribbon Spindle Unit
is identical across the horizontal centerline. The placement on the Ribbon Drive
Spindles will determine the correct position. (See illustrations on the following
pages.) Unwind approximately 6" of the leader. Press the empty take-up core on
the opposite spindle. Make sure each of the cores is fully seated on the spindles.
7.
Slide the Ribbon Spindle Unit over the ribbon drive spindles. Be sure to engage
the ribbon Spindle Unit in the track on the print head. (See illustrations.)
Continue to slide the unit until the Head Positioning Latch snaps into position.
The first position corresponds to a 4.3" ribbon width. If you are using a
narrower ribbon, press the Head Position Latch while sliding the Ribbon Spindle
Unit to the correct position. There are three latch positions for different width
size ribbons, 4.3", 3" and 1.75" widths.
8.
Page 1-8
CT Series ribbons are wound face (ink side) out. Make sure the dull (ink) side
of the ribbon will be in contact with the paper and the supply core is on the rear
spindle. The ribbon should be center justified (i.e., the center of the ribbon roll
should be aligned with the center of the print head). If it is not, reposition the
Ribbon Spindle Unit on the Drive Spindles until the Ribbon Position Latch is in
the correct position.

STEP
1.
PROCEDURE
Switch the printer OFF.
FOLLOW ILLUSTRATION SEQUENCE A-I
2.
Open the top cover by pressing on the cover release points located on each
side of the printer. This releases the cover latch and allows it to swing
upward on the rear mounted hinge points.
3.
Release the head by pressing the Head Latch to the rear. This allows the
Ribbon and Print Head Assembly to swing upward to the left allowing easy
access for media routing. Rotate the assembly until it is vertical.
4.
With the Print Head Assembly in the up position, press the Paper Guide
Release button while adjusting the Paper Guides until they allow a media
roll to fit between them. A millimeter scale is molded into the case to
provide a guide when making the adjustment. The Paper Guides are center
justified and linked together so that each moves an equal distance.
5.
Make sure the Roll Holders are in the released position. If they are not, lift
up on each one and they will snap to the open position.
6.
Unwind approximately 12" of label material from the roll. The labels
should be wound face-out (printing side to the outside of the roll). Drop
the roll in between the Paper Guides so that the labels come off the top of
the roll. The Paper Guides will automatically position the Roll Holders to
suspend the roll.
7.

1.10 Installation Considerations
Printer operation can be affected by the printer environment. The location of the
printer should be free from dust, humidity and sudden vibrations. To obtain optimum
results from the printer, avoid locations influenced by:
•
Direct or bright sunlight, since bright light will make the label sensor less responsive
and may cause the label to be sensed incorrectly.
•
Warm temperatures which can cause electrical problems within the printer. (See
Section 1.12 Environment.

2.5 Label Sensing
The CT Series printers can use either Label Gap (see-thru) or Eye-Mark (reflective)
sensing. The Sensor Assembly is located on the left edge of the media and is automatically positioned by the paper guides.
The printer is shipped from the factory with the default sensing method set for label
gap. The setting can be overridden by using the <ESC>IG command, however it will
be reset to the default when power is cycled. The default setting can be changed
using the <ESC>PB command or the Printer Configuration Utility program on the
CD-ROM.

2.6 CT400/410 Driver Installation
To install the CT400 printer driver in Windows 95/98, Windows NT 4.0, or Windows
2000, please follow the steps outlined below. We do not have a Windows driver
available for Windows 3.1/3.11.
If you are currently using a label production program that doesn’t support the use of
Windows Drivers but has SATO drivers included, you will have to contact the company
that writes that software. If they do not support the CT400 or CT410 you can use the
CL408 or CL412 driver; keeping in mind that what you see on the screen may not be
exactly what is printed on the printer. When using these drivers all design will have to
be based on a 4” wide label do to the fact that the CT printers are center justified;
Meaning if you have a 2” wide label installed on the CT printer, you will have to
design a 4” wide label within your application, and then only design on the middle 2”
of the label.
Note: Your screen resolution must be set to at least 800x600 pixels for you to be able to
view every portion of the driver’s properties. To adjust this you must go to your Start
Menu – Settings – Control Panel – Display. Once in the display properties you need to go
to the Settings Tab and then change the Screen Area to a size at least as big as 800x600.
Warning: An IEEE1284 compliant parallel cable must be used with
this printer. If any other Parallel cable is used, this driver will not
function properly and many of the printer’s features will be
inaccessible.
1. Insert the CD labeled CT400 into your CD-ROM drive. Within 1 minute the
following screen should appear:
If this screen does not appear go to Step 2. If this screen appears skip to Step 3.

Interface Specifications
3.1 Overview
This section presents the interface specifications for the CT Series printers.
These specifications include detailed information on how to properly interface
your printer with your host system.
The following information is presented in this section.
•
Interface Types
•
Universal Serial Bus (USB) Interface
•
The Receive Buffer
•
Local Area Network (LAN) Interface
•
IEEE 1284 Parallel Interface
•
Bi-Com Communications Protocol
•
Optional RS232 Serial Interface
•
Status Response
3.2 Interface Types
The standard interface for the CT printers is a high speed, bi-directional parallel
interface that conforms to the IEEE 1284 specification. The interface is also compatible
with the older Centronics parallel interface standard. If it does not detect the correct
IEEE 1284 signals in the interface connection, it will automatically operate in the
standard Centronics mode which is much slower. To use the IEEE 1284 parallel
interface to its fullest capability requires that the host also have an IEEE 1284
compatible interface and that the two be connected with a cable that meets the IEEE
1284 specification. If either of these two are not present, the data rate is severely
compromised.
In order to provide flexibility in communicating with a variety of host computer systems,
all CT Series printers can be configured for operation with either an optional serial
interface or an optional Universal Serial Bus (USB) interface. These optional interfaces
are available as factory installed options only and must be specified at the time of order.
The Parallel interface will probably be the most useful in communicating with IBM PCs
and compatibles. The RS232C Serial interface allows connectivity to a number of other
hosts. The USB interface allows the printer to be connected to a computer that supports
peripherals attached to a USB bus. Up to 127 peripherals can be connected to a single
USB port.

Section 3. Interface Specifications
Interface Types
When using an optional interface, DSW-8 on the Configuration panel must be placed in the OFF
position. When the IEEE 1284 interface is to be used, DSW-8 must be placed in the ON
position.
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 warranty.
Available Interfaces
CENTRONICS PARALLEL provides a means of communicating with IBM
PCs and compatibles.
RS232C SERIAL allows connectivity to a number of other hosts.
USB SERIAL provides Microsoft Plug and Play specification allowing for
hot-swapping.
ETHERNET provides a direct connection from the printer to all major
ethernet networking systems, including Microsoft, Novell, UNIC and
IBM.
TWINAX/COAX enables printers to be connected to IBM midrange and
mainframe systems, such as the AS400.

Section 3. Interface Specifications
3.3 The Receive Buffer
The CT Series printer has the ability to receive a data stream from the host in one of
two ways. The receive buffer may be configured to accept one print job at a time or
multiple print jobs. The single job print buffer is generally used by software programs
that wish to maintain control of the job print queue sot that it can move a high
priority job in front of ones of lesser importance. The multiple job buffer on the other
hand prints all jobs in the order they are received by the printer and the order of
printing cannot be changed.
Single Job Buffer
The printer receives and prints one job at a time. Each job must not exceed 2.95MB.
Multi Job Buffer
The printer is able to continuously receive print jobs, compiling and printing other
jobs at the same time. It acts much like a "print buffer" ot maximize the performance
of the host and the printer.
1.95MB
0
*DTR High
or

or

X-Off
* Data Terminal Ready
When using the RS232 Serial interface, the Multi Job Buffer uses either the
Ready/Busy with DTR (pin 20) or X-On/X-Off flow control protocols. See
these sections for more details. With an empty receiving buffer, the status of DTR
is "high" (or an X-On status if using X-On/X-Off), meaning the printer is ready to
receive data. When the receive buffer is holding 1.95MB of data (1.95MB from
being full), DTR will go "low" (or an X-Off is sent) indicating the printer can no
longer receive data. This condition is called "Buffer Near Full" (see figure below).

The Receive Buffer (Cont.)
The receiving buffer will not be able to receive more data again until a "Buffer
Available" condition occurs. This takes place when the receiving buffer has emptied so
that only 1MB of data are being held (1.95MB from being full). At this time DTR will
go "high" or an X-On is sent to tell the host that it can again receive data.
All printer error conditions (i.e., label out) will cause the printer to go busy (DTR "low"
or X-Off) until the problem is corrected and the printer is placed on-line. The printer
will also be busy if taken off-line from the front panel.
3.4 IEEE 1284 Parallel Interface
The parallel interface for the CT printers conforms to the IEEE 1284 specification. It will
automatically detect the IEEE 1284 signals and operate in the high speed mode. If it does
not detect the IEEE 1284 signals, it will operate in the standard Centronics mode, which is
significantly slower. For this reason, an interface cable and host interface conforming to
the IEEE 1284 specification must be present to fully utilize the speed capabilities. This
interface also operates bi-directionally and can report the status of the printer back to the
host.
DSW-8 on the Configuration Panel must be in the ON position to activate the parallel
interface.

Ready/Busy Flow Control
Ready/Busy is the hardware flow control for the serial interface on the CT Series printer.
By raising/lowering the voltage level on Pin 20 of the RS232 port, the printer notifies the
host when it is ready to receive data. Pin 4 (RTS) and pin 20 (DTR) are the important
signals on the printer for this method of flow control. The host must be capable of
supporting this flow control method for it to function properly.

printing in the Single Job Buffer mode. It will also go low
when the data in the buffer reaches the Buffer Near Full
level.
SATO CT Series Printers Service Manual
PN 9001095
Rev. B
Section 3. Interface Specifications
X-On/X-Off Flow Control
X-On/X-Off flow control must be used whenever hardware (Ready/Busy) flow control
is not available or desirable. Instead of a voltage going high/low at pin 20, control
characters representing "Printer Ready" (X-On = 11 hexadecimal) or "Printer Busy" (XOff = 13 hexadecimal) are transmitted by the printer on pin 2 (Transmit Data) to the
host. In order for this method of flow control to function correctly, the host must be
capable of supporting it. X-On/X-Off operates in a manner similar to the function of
pin 20 (DTR) as previously explained. When the printer is first powered on and goes
on-line, an X-On is sent out. In the Single Buffer mode, when the printer receives a
viable job, it transmits an X-Off and begins printing. When it is done printing it
transmits an X-On. In the Multi Job Buffer mode, the printer sends an X-Off when the
"Buffer Near Full" level is reached and a X-On when the data level of the buffer drops
below the "Buffer Available" mark. When the printer is taken off-line manually it
transmits an X-Off indicating it cannot accept data. When it is placed back on line
manually, it sends an X-On, indicating it is again available for receipt of data. If an error
occurs during printing (paper out), the printer sends nothing in the Single Job Buffer
mode since the last character transmitted was an X-Off. When the error is cleared and
the printer resumes printing no X-On is sent until the current job is completed and the
printer is once again ready to receive the next job. If it is in the Multi Job Buffer mode it
sends an X-Off as soon as an error condition detected. When the error is cleared and
the printer is placed back on-line, it transmits as X-On indicating it is again ready to
accept data.
Upon power up if no error conditions are present, the printer will continually send
X-On characters at five millisecond intervals until it receives a transmission from the
host.
Data Streams
The data streams for X-On/X-Off and Ready/Busy flow control are constucted in the
same way as they are for Ready/Busy flow control.

Example: <ESC>A .. Job#1 .. <ESC>Z
NOTE: All characters are in ASCII.
3.6 Universal Serial Bus (USB) Interface
The Universal Serial Bus (USB) interface is a factory installed option that must be
specified at the time of order. When it is installed, the printer can be configured to
receive data through the IEEE 1284 parallel interface or the optional USB interface. It
requires a driver (shipped with each printer that has the interface installed) that must be
loaded on your PC and the PC must be configured to support USB peripherals. Windows
2000, Windows 98 and Windows 95/R2 support USB peripherals. Details for loading the
USB driver are contained in the USB Interface Manual that is shipped with each printer
with a USB Optional interface installed. Up to 127 devices may be connected to a USB
port.

3.7 Local Area Network (LAN) Interface
A Local Area Network (LAN) interface is a factory installed interface option that must be
specified at the time of order. When it is installed, the printer can be configured to receive
data through the IEEE 1284 parallel interface or the optional LAN interface. It requires a
driver (shipped with each printer that has the interface installed) that must be loaded on
your PC and the PC must be configured to support the TCP/IP network protocol using a
10BaseT LAN connection. Details for loading the LAN driver are contained in the LAN
Interface Manual that is shipped with each printer with a LAN Optional interface installed.
3.8 Bi-Directional Communications
This is a two-way communications protocol between the host computer and the printer, thus
enabling the host to check printer status. When Bi-Com communications is selected, there is
no busy signal from the printer. The host must request the complete status from the printer,
including ready/busy. The host may request status in two different ways.
ENQUIRE/ACK/NAK
In the first mode, it transmits an ENQ (05 hexadecimal) to the printer and the printer will
respond with its status within five milliseconds. If printing, it will respond upon finishing
the current label, then resume printing. In order for this protocol to work properly with
an RS232 Optional Interface, pin 6 (DTR) and pin 5 (CTS) must be held high by the host.
One way to ensure these pins are always in the correct state is to tie pin 20 (DTR) to pin
6 (DSR) and pin 4 (RTS) to pin 5 (CTS) at the printer end of the cable.
Enquire (ENQ)
Upon receipt of an ENQ command, the printer responds with nine bytes of status
information bounded by an STX/ETX pair. The Bi-Com protocol works only in the Multi
Job Buffer mode. The status information is defined as follows:
<STX>{2 Byte ID}{1 Status Byte}{6 Byte Label Remaining}{16 Byte Job Name}<ETX>
ID - This is a two byte number identifying the current print job ID. The print job
ID is defined using the <ESC>ID Job ID command transmitted with the print job
(see Job ID Store in the command listing for more infomation on how to use this
command). The range is from 00 to 99.
Status - A single byte defining the current status of the printer (see the Status
Byte Definition table).
Label Remaining - Six bytes defining the number of labels remaining in the
current print job. The range is from 000000 to 999999 labels.
Job Name - Sixteen bytes of ASCII characters identifying the name assigned to
the job by the <ESC>WK Job Name command.
If an ENQ is received after the print job specified in the ID bytes has been
completed, or there is no data in the buffer, the printer will respond with two
"space" characters (20 hexadecimal) for the ID number and six "zero" characters
(30 hexadecimal) in the Remaining Labels bytes.

SATO CT Series Printers Service Manual
PN 9001095
Rev. B
Section 3. Interface Specifications
Cancel (CAN)
If a CAN (18 hexadecimal) command is received, it will stop the print job and clear all data
from the receive and print buffers. A delay of five milliseconds or more is required before
an new data can be downloaded. The CAN command is effective immediately upon
receipt, even if the printer is off-line or in an error condition. The printer will return an
ACK (06 hexadecimal) if there is no printer error condition and a NAK (15 hexadecimal) if
an error condition exists.
Print Job
Upon receipt of a valid print job (<ESC>A ...<ESC>Z), an ACK (06 hexadecimal) will
be returned by the printer if there are no errors and an NAK (16 hexadecimal) if a printer
error exists.
Print Stop (DLE)
If a DLE (10 hexadecimal) is received by the printer, the print process is stopped and an
ACK (06 hexadecimal) is returned if there are no errors and a NAK (16 hexadecimal) if a
printer error exists.
Print Start (DC1)
If the printer has been stopped by receipt of a DLE (10 hexadecimal) command, it can be
restarted by sending a DC1 (hexadecimal 11) command. Upon receipt of this command an
ACK (06 hexadecimal) is returned if there are no errors and a NAK (16 hexadecimal) if a
printer error exists.
(1) To provide compatibility with older SATO printers, the RS232 interface can be
configured to use an earlier ENQ/ACK/NAK protocol. The earlier protocol did not have
provisions for the Job Name and did not respond to the DLE or DCI commands. Also,
there are additional Response Codes in the Status Byte Definition. It is recommended
that you use the current protocol rather than the earlier version unless it is necessary for
compatibility with existing sofware.

Status Response
The second method of determining printer status is to interrograte the printer with
specific commands. The response from these commands will provide specific information
about the printer status depending upon the command. This allows the controlling
application to determine the status of a printer when it is located in a remote location.
Print Status (SOH + MG)
Upon receipt of an SOH (hexadecimal 01) followed immediately by an ASCII MG
causes the printer to return a 30 byte Printer Status Word bounded by an STX-ETX pair

4.1 Overview
This chapter describes how to check CT Series Printers voltage levels and adjust threshold
sensor voltages.
The power supply converts 125 VAC into regulated DC voltages. The printer uses: +5V
and +24V. These DC voltages are not adjustable, however you can measure these DC
voltages at test points located on the PCB. Section 4-2 contains procedures for measuring
DC voltage levels.
You can adjust threshold voltage levels for label sensors. These adjustments are made to
allow for variations in the characteristics of the labels used with the printer. If you cannot
calibrate the label sensor voltage level within the specified voltage range, you should
reposition the label sensor by following the adjustment procedures included in this
section. After completing the label sensor adjustment procedures, perform the label
sensor voltage level adjustment procedure.
You can check or adjust:

Offset Settings
There are three offset settings stored in the printer; one for Dispense mode, one
for Cut mode and one for the Tear-Off mode. These three offsets can be set
independently for each job using the <ESC>PO Pitch Offset command and will
remain in the printer until a new command is received changing the setting or
until power is turned off. The <ESC>PG Printer Setting command can be
determined by printing a User Test Label or displayed by the Printer Configuration
Utility Program on the CD-ROM. Please note that the Printer Configuration Utility
Program requires a bi-directional communications port on a host that is running
Windows 9X.

Potentiometer Assignments & Adjustments
After the Label Offset has been set using the <ESC>PO Pitch Offset command, it
is sometimes desireable to make minor adjustments. This can be done using the
VR1 potentiometer on the Configuration Panel. This potentiometer is set at the
factory so that it has a range of +/- 3.75 mm. The midpoint setting should have
no effect on the label pitch. Turning the potentiometer all the way clockwise
should move the print position 3.75 mm upwards towards the leding edge of the
label. Turning it all the way counterclockwise should move the print position
down 3.75 mm away from the leading edge of the label
STEP
PROCEDURE
1.
Record all current dip switch positions, then place all switches in the OFF
position and the power switch OFF.
2.
Press the FEED key while simultaneously turning the POWER switch ON.
3.
When the printer beeps, release the FEED key.
4.
To print a large (4" wide) Test label:
Press the ON LINE key (or),
To print a label smaller than 4.1" ( 104 mm) in width:
Press the FEED key.

5.
PROCEDURE
Adjust the potentiometer VR1 until the first print position is at the
desired location on the label. If the potentiometer does not have enough
range, you will have to change the Label Pitch setting using the
<ESC>PO command.
Note: The printer will return to the default settings specified by the
<ESC>PG command when power is cycled.
6.
Press the FEED key to stop the printing.
Note: Adjusting the Label Pitch with VR1 will affect the stop position of
the label and the cut/dispense/tear-off positions.
4.4 Print Darkness
Print Darkness is set using the <ESC>#E Print Darkness command. A fine
adjustment for PRINT DARKNESS can be made using potentiometer VR1 on the
Front Operator Panel. It provides a continuous rante of adjustment, allowing you
to make precise changes. Turning VR1 clockwise will make the print darker and
counterclockwise will make it lighter.

6.2 Preparing the Printer for Servicing
Caution!
Some of the components in the printer are extremely sensitive to static discharge
damage. When servicing the printer, observe good static prevention practices.
• Place the printer on a grounded, conductive work surface.
• Ground yourself to the work surface through a 1 megohm series resistor using a
conductive wrist strap or other suitable device.
• Ground any tools that will contact the equipment, (holding the conductive
portion of the tools can provide a suitable ground).
• Keep replacement components in their protective packing until they are needed,
and do not handle unnecessarily.
After repairs are completed:
After making the necessary repairs, reconnect the printer power supply and reinstall
the label stock. Confirm that the printer status LED glows green, and that the
printer will feed a label when you press the FEED button.
For access to the internal components, turn the printer over and remove (4)
screws from the base cover.

The print head on the CT Series printer is a user-replaceable item. This section explains
how a defective print head can be easily removed and replaced. Contact you local SATO
representative for information on obtaining a new print head.
NOTE: The print head contains a precision printing surface that must be carefully
protected from mechanical damage. Extreme care must be exercised during handling
and installing to prevent scratching, chipping, denting or otherwise damaging the
exposed substrate surface, particularly in the resistor (printing element) area. A small
clean piece of cardboard should be used to protect the substrate during installation if
there is a possibility of accidental damage.

The design of CT Series Printers is based on proven technology and reliable components.
When a problem occurs, the solution can be easily traced using the troubleshooting tables
in this section. These tables list symptoms, probable causes, and suggested corrective
actions.
Make sure the basics have been checked before deciding you are unable to proceed any
further. To help you, this section has been divided into the following sections:

Section 8. Troubleshooting
8-2 Initial Check List
If you are unable to produce output on your printer, check the following before deciding
you're unable to proceed any further.
1. Is the printer 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 exists.
3. Is the Print Head and the Label Hold Down in the down and latched position?
Other areas that may need looking at include:
8-3 Troubleshooting the IEEE 1284 Parallel Interface
1. Is the IEEE 1284 printer cable connected securely to your parallel port (DB25S
Female) on the PC and to the parallel connector on the printer?
WARNING: Never connect or disconnect interface cables (or use a switch box) with power
applied to either the printer or the host. This may cause damage to the interface circuitry
and is not covered by warranty.
2. Does the parallel interface cable used meet IEEE 1284 specifications?
3. 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.
4. Is the IEEE 1284 interface selected? DSW-8 must be in the OFF position to enable the
parallel interface.
5. When you send the print job to the printer, 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 printer is there. Verify that:
a. Both ends of the cable are securely inserted into their respective connectors.
b. The printer is ON-LINE.
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.
5. When you send the print job to the printer and it does not respond, and there is no
error message on the PC:
a. Check you data stream for some of the basics. Is your job framed as follows?

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 printer command codes are capital letters.
6. If you've checked all the above and the printer still isn't printing, you may want to try
a Receive Buffer Hex Dump to determine what (if anything) the printer is receiving
from your computer. See Hex Dump Diagnostic Labels.
The Parallel port is now listening for incoming data. Send your print job. The
printer 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 printer received. It may be tedious, but now you can analyze and
troubleshoot the data stream.
WARNING: A small label may produce a large amount of data when
printed in Hex Dump.
7. While checking the Hex Dump printout, look for 0D 0A (Zero D Zero A) (Carriage
Return and Line Feed) characters throughout. The command string should be
continuous. CR or LF characters are not allowed 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.
If you're 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 printer. We want the data stream to be one complete
line going to the printer.

Section 8. Troubleshooting
8-4 Troubleshooting the RS232C (Serial) Interface
1. Is the RS232C Serial cable connected securely to your serial port on the PC (DB-25S
or DB-9S Male) and to the RS232C connector on the printer?
Warning: Never connect or disconnect interface cables (or use a switch box) with power
applied to either the printer or the host. This may cause damage to the interface circuitry
and is not covered by warranty.
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 printer to print. We
recommend that you use a cable built to specifications described in Section 3,
Interface Specifications.
3. Is the RS232 Interface option installed in the printer? DSW-8 must be in the ON
position to enable the Optional Interface.
4. Check for obvious errors in the data stream. Is the data properly framed with the
<ESC>A and <ESC>Z commands?
5. If after sending your job to the printer, it only "beeps" and displays an error message
of the 7 segment display, 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 unsure as to what the printer'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 databits, and 1 stop bit.
6. If you still are unable to get printer output, try the Hex Dump as described in Step 5
under the Centronics Interface troubleshooting. In this case, the printer monitors its
RS232C interface for incoming data.

Open the top cover by pressing on the cover release points located on each
side of the printer. This releases the cover latch and allows it to swing
upward on the rear mounted hinge points.
Release the head by pressing the Head Latch to the rear. This allows the
Ribbon and Print Head Assembly to swing upward to the left allowing easy
access for media routing.
Press the Paper Guide Release button while adjusting the Paper Guides until
they allow a media roll to fit between them. A millimeter scale is molded
into the case to provide a guide when making the adjustment. The Paper
Guides are center justified and linked together so that each moves an equal
distance.
Make sure the Roll Holders are in the released position. If they are not, lift
up on each one and they will snap to the open position.
Unwind approximately 12" of label material from the roll. Allow for
several inches of blank label backing. The labels should be wound face-out
(printing side to the outside of the roll). Drop the roll in between the Paper
Guides so that the labels come off the top of the roll. The Paper Guides will
automatically position the Roll Holders to suspend the roll.
Flip down the front cover. Press down on the bar release points and swing
forward.
Route the label material through the Notch/Gap Sensor and over the
Platen.
Route label backing behind roller, on top of the dispenser lid and out the
front of the printer.
Close and latch the Print Head Assembly. Snap the release bar into position
and close the front cover.
Turn on the printer. Press the ON LINE button to place printer in off line
mode. Press the FEED button to dispense a label.

Fanfold Media
STEP
PROCEDURE
1.
Switch the printer OFF.
2.
Carefully break out the fanfold access panel from the back, of the Top
Cover.
3.
Place the fanfold media behind the printer with the printing surface up.
4.
Open the top cover by pressing on the cover release points located on each
side of the printer. This releases the cover latch and allows it to swing
upward on the rear mounted hinge points.
5.
Release the head by pressing the Head Latch to the rear. This allows the
Ribbon and Print Head Assembly to rotate upward to the left allowing easy
access for media routing. Rotate the assembly until it is vertical.
6.
With the Print Head Assembly in the up position, press the Paper Guide
Release while adjusting the Paper Guides until they allow a media roll to fit
between them. A millimeter scale is molded into the case to provide a guide
when making the adjustment. The Paper Guides are center justified and
linked together so that each moves an equal distance.
7.
Route the label material through the Notch/Gap Sensor and over the
Platen.
8.
Close and latch the Print Head Assembly.

9.5 Interface Installation Preparation
To install the interface kits, the base plate must be removed for access to the main
pcb and the interface knockout slot must be broken out from the base plate.
Caution!
Some of the components in the printer are extremely sensitive to static discharge
damage. When servicing the printer, observe good static prevention practices.
• Place the printer on a grounded, conductive work surface.
• Ground yourself to the work surface through a 1 megohm series resistor using a
conductive wrist strap or other suitable device.
• Ground any tools that will contact the equipment, (holding the conductive
portion of the tools can provide a suitable ground).
• Keep installation components in their protective packing until they are needed,
and do not handle unnecessarily.
After installation is completed:
Reconnect the printer power supply and reinstall the label stock. Confirm that the
printer status LED glows green, and that the printer will feed a label when you press
the FEED button.
