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
speed capabilities. This interface also operates bi-directionally and can report the status of the printer back to the
host.

UNIVERSAL SERIAL BUS (USB)
The Universal Serial Bus (USB) interface is a Plug-In Interface Module that can be installed by the user. It requires
a driver (shipped with each printer that has the interface installed) that must be loaded onto the PC and configured
to support USB peripherals using Windows 2000 or above. 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 using powered hubs.
ATTENTION: This Interface Type Is Not Compatible With Windows 98 Or Windows
Me.

LOCAL AREA NETWORK (LAN) ETHERNET
A Local Area Network (LAN) interface is an optional Plug-In Interface Module that can be installed by the user. It
requires a driver shipped with each printer that has the interface installed. The driver that must be loaded onto the
host computer and configured to run one of the supported network protocols using a 10Base-T or 100Base-TX
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.

NOTE: Print data can be sent by LPR and FTP of TCP/IP and dedicated socket protocol. Printer status is obtainable by
dedicated socket protocol.
NOTE: In the TCP/IP protocol environment, LPD and FTP are provided for printing; TELNET for variable setup; ARP, RARP,
and BOOTP/DHCP for address setup.
LPD protocol complies with RFC1179 and handles the list of logical printer name as queue name such as lp, sjis, euc. In
addition, a banner page can be printed by a proper setup.
When sending the job by LPR, the transmission order of data file/control file within the job will not affect print operation. In
addition, if the banner page is specified, it will be added to each data file. Job deletion by LPR is not available.
FTP protocol complies with RFC959 and handles the list of logical printer name as a transfer directory. File transfer to this
directory executes print operation. It is possible to specify ASCII(A), Binary(I) and TENEX(L8) as transfer mode - although the
mode difference is dependent on the client. A banner page may be printed with a proper setup.
TELNET Complies with RFC854. This operation consists of interactive menu form and enables change and reference of
internal setup, and to display status. To change the setup, enter “root” user and password at the time of login. Default of root
password is set as null (linefeed only).

and BOOTP/DHCP for address setup.
LPD protocol complies with RFC1179 and handles the list of logical printer name as queue name such as lp, sjis, euc. In
addition, a banner page can be printed by a proper setup.
When sending the job by LPR, the transmission order of data file/control file within the job will not affect print operation. In
addition, if the banner page is specified, it will be added to each data file. Job deletion by LPR is not available.
FTP protocol complies with RFC959 and handles the list of logical printer name as a transfer directory. File transfer to this
directory executes print operation. It is possible to specify ASCII(A), Binary(I) and TENEX(L8) as transfer mode - although the
mode difference is dependent on the client. A banner page may be printed with a proper setup.
TELNET Complies with RFC854. This operation consists of interactive menu form and enables change and reference of
internal setup, and to display status. To change the setup, enter “root” user and password at the time of login. Default of root
password is set as null (linefeed only).

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. 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.

MEDIA SELECTION
The size and type of the labels or tags 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 on it and wear it out. The media edge will also wear a groove
in the platen roller affecting print quality.
MEDIA LOADING: ROLLED PAPER
There are two general label types that may be loaded and used; rolled and fan-folded. Each of those types may
again be defined by whether their print application is direct thermal or thermal transfer. Those factors determine
how the media is loaded and if ribbon stock is loaded at all.
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 transferred to the media. Direct thermal media has a coating
on the surface that is made visible through the application of heat from the print head. Rolled media of standard
diameter is loaded within the printer and suspended by the media holder.

OPERATIONAL MODE SELECTION
There are two modes of printer operation; Dispense and 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 the functional differences between the two.
ATTENTION: Refer to the Printer Configuration unit of this manual to program the
printer’s internal memory to suit individual needs using the integrated menu options.
Refer to the Programming Reference document to remotely program the printer’s
features and functions through a host system.
CONTINUOUS MODE
With this mode of operation, the media remains in position for printing at all times. To do so, means that the
previous printed label is only available for removal when one to four additional labels have been printed (quantity is
depended on label size). This mode of operation is specifically suited for printing bulk quantities to be applied later.
TEAR-OFF 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 removal. Printing of the next label will not begin until the prior printed label has been
removed. This mode of operation is specifically suited for immediate application at the time of print.
Upon removal of the prior printed label, the printer retracts the media so that the next label in line may be printed,
then prints. This cycle, repeats for each consecutive label.
CUTTER MODE
With the cutter assembly installed and enabled, this mode of operation will cut individual printed labels or in
multiples. The media will be advanced to the cutter blade, the label cut will occur, and the unprinted media will
retract for positioning of the next print.
DISPENSE MODE
When the dispenser assembly is installed and enabled, this mode of operation will peel the paper backing from the
printed label as it is advanced to the printer’s front. Once the printed label has been removed from the printer for
application, the unprinted media will retract and position itself so the next label may be printed.
This operational mode is specifically applicable to print operations where the label is to be immediately adhered.
LINERLESS MODE
When the linerless option is installed and enabled, this mode of operation allows for the feeding and printing of
linerless media. In this mode, the printer’s functionality is the same as with the continuous or tear-off modes -
depending on configuration settings.

• During a print job, pressing the ONLINE button will pause the job. Press the ONLINE button again to resume the job.
• Pressing the FEED button in OFFLINE mode will advance a blank label if the label sensor is enabled.
• Pressing the FEED button in OFFLINE mode if the label sensor is disabled, results in the paper size not being verified and
the paper is fed in as long as the FEED button is held down. The feed procedure is stopped as soon as the FEED button is
released. Also, for concurrent cutter/liner-less operation, the paper cutting is executed as soon as the feed is halted (the
feed button is released). A back-feed may be performed after the cut has been executed.
• Taking the printer OFFLINE and pressing the ONLINE and FEED buttons will disable response to any JOB-CANCEL
command from the host computer. Then press the FEED button to return to OFFLINE mode. The LED shows

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 interfaces or interface card are 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.
Try another port to isolate the problem.
Replace the main circuit board 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.
Try another port to isolate the problem.
Replace the main circuit board 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:
CHK
TROUBLESHOOTING STEP
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.

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.
802.11G WIRELESS INTERFACE
CHK
TROUBLESHOOTING STEP
Ensure the antenna is properly and completely installed.
Ensure the wireless card is properly installed.
Ensure the green connection lights on the back of the interface board are illuminated.
If not obtaining an IP address, check the SSID or encryption and ensure those were properly entered.
To determine the IP address obtained through the DHCP wireless device, power off the printer, place switch 3 in the
upward position on the wireless card and reinsert it into the printer, and power the printer on. Wait approximately 30
seconds for a print out of configurations.
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 0D Hex and/
or 0A Hex (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 main circuit board with another to isolate the problem.

CLEANING PROCEDURES
Cleaning of the printer is a necessary maintenance 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 (available separately) or isopropryl alcohol
to a clean cotton swab and gently wipe the entire surface of the print head and platen roller clean.
Of particular importance is the care and maintenance of Print Heads. Efforts should be made to educate
printer operators and their supervisors to refer to this Operator's Manual or other relevant documentation
when cleaning the print head, platen and rollers. Regular cleaning regimes should be enforced to make
sure that he printer and the immediate production area are cleaned regularly to minimize dust buildup.
Properly adjustment of the print head balance should be done periodically, and the use of certified SATO
consumables will maximize output quality and minimize print head replacement. For pre-printed labels,
ensure that ad-hoc testing is conducted so that the materials are print-head safe.
Finally, efforts should be made to ensure that operators and their supervisors do not compensate for
print quality problems by adjusting print darkness/print speed settings unnecessarily. When print heads
show signs of problems, do not allow them to continue being used. To this end, SATO Service Contracts
are highly recommended, to help businesses to reduce downtime while maximizing the durability and
usable life of the printer.
WARNING: DISCONNECT POWER TO THE PRINTER AND ALLOW THE LATTER
TO COOL TO ROOM TEMPERATURE PRIOR TO CLEANING. EXCERSIZE CARE
WHEN CLEANING TO PREVENT PERSONAL INJURY.
CAUTION: IF USING A PNEUMATIC BLOWER TO REMOVE DEBRIS FROM THE
PRINTER, EXCERSIZE CARE TO PREVENT PRINT HEAD DAMAGE.

ADJUSTMENT PROCEDURES
This section provides information on user maintenance for the SATO Ct4xxi printer. This section
contains the following information.
• Adjusting the Print Quality
• Cleaning the Print Head, Platen and Rollers
• Replacing the Print Head
ADJUSTING THE PRINT QUALITY
The SATO CT4xxi printer is equipped with two different methods of adjusting the quality of the print—
print darkness and print speed.
When adjusting the printer for optimum print quality, a barcode verifier system is highly recommended
for evaluating the printouts. The human eye is a poor judge of the relative widths of the bars in a symbol,
a characteristic that is extremely important for good bar code quality.
Print Darkness
This adjustment allows the user to control (within a specified range) the amount of power that is used to
activate the print head heating elements. It is important to find a proper print darkness level based on
your particular label. The printed images should not be too light nor should the edges of text or graphics
be smudged. Instead, the edges of each image should be crisp and well defined.
Once the range has been selected, the PRINT Potentiometer (VR1) on the front panel can be used to
make finer adjustments. It provides a continuous range of adjustment, allowing you to make precise
changes. Use a small cross-point screwdriver, turning clockwise for darker print and counterclockwise
for lighter print. See page 3-3 for instructions on performing potentiometer adjustments
Print Speed
The other method of controlling print quality is by controlling the speed at which the label is printed. It is
especially critical when printing "ladder" bar codes (bar codes printed with the bars parallel to the print
line). When printing a "ladder" bar code, it is important to allow the head to cool sufficiently before
stepping to the next position. If it does not have sufficient time to cool, the bar will be "smeared" on the
trailing edge. The adjustment can be made via standard SBPL commands. For more information refer to
the SBPL Programming Reference.

CLEANING THE PRINT HEAD, PLATEN AND ROLLERS
Cleaning the Print Head
1. Before starting, get ready an approved cleaning kit from your
SATO dealer or the kit supplied with the printer. Make sure the
printer is OFF, and remove the power cable.
2. Lift up the Top Cover and locate the Print Head Assembly which
is mounted under the cover.
3. Apply Thermal Print Head Cleaner to a cotton swab.
4. The Print Head faces downward along the front edge of the
assembly. Pass the end of the dampened swab along the entire
width of the Print Head.
Figure 6-1, Cleaning the print head
5. Check for any black coloring or adhesive on the swab after cleaning.
6. Repeat if necessary until the swab is clean after it is passed over the head.
7. The head should be cleaned at least every time the label roll is changed, and more often in harsh
environments.
Clearning Stubborn Debris on the Print Head
1. If certain stains on the print head cannot be removed easily with
cotton swabs dabbed in cleaning solution, obtain cleaning
sheets designed for cleaning print heads (for such supplies,
contact your SATO dealer).
2. Load the cleaning sheet with the rough side facing the print
head. Follow any other instructions or precautions printed on
any leaflet that may accompany the cleaning sheet.
3. With the printer turned OFF, and the Top Cover closed, slowly
pull the cleaning sheet outwards. Repeat the process until the
print head is clean.

CLEANING THE PRINT HEAD, PLATEN AND ROLLERS (CONT’D)
Cleaning the Platen and Paper Roller
1. Before starting, get ready an approved cleaning kit from your
SATO dealer or the kit supplied with the printer. Make sure the
printer is OFF, and remove the power cable.
2. Lift up the Top Cover.
3. The platen roller is the black rubber roller near the front panel.
The print rollers are located at the print head assembly, near the
fanfold-label loading window.
4. Wet some cotton swabs with cleaning solution. While rotating
the platen roller with your fingers, clean the entire length of the
roller using one or more cotton
Figure 6-4, Cleaning the platen
swabs. The roller should be cleaned of any label or
adhesive residue.
5. Repeat the whole cleaning process if necessary. The platen
and rollers should be cleaned whenever foreign matter such as
dust or adhesive is present.

RELEASING/REPLACING THE PRINT HEAD
The print head on the printer is a user-replaceable item. If it becomes damaged for any reason, it can be
easily removed and replaced. Contact your local SATO representative for information on obtaining a
new print head. You will also need a No. 2 Phillips screwdriver (a magnetic tip is helpful) for the
replacement procedure.
1. Make sure the printer is OFF, and remove the power cable.
2. Lift up the Top Cover.
3. Locate the small center tab (see red arrow) above the print head.
Press and hold down this tab. At the same time, pull the whole print
head below it, downwards if it does not drop downwards automati-
cally.
The cable connector (circled red here) at the rear of the print head is now
exposed. Pull the print head downwards, then gently disconnect the print
head from the cable.
4. Carefully attach a replacement print head to the cable connector.
The connectors are keyed so that they can only be inserted in the
correct orientation.
Note:
While handling the print head, be careful not to scratch the printing
surface of the print head. Scratching the surface will cause perma-
nent and irreparable damage that is not covered by the warranty!
5. Reinsert the print head into the printer, making sure that the metal
slots at the two sides of the print head fit back over the round pur-
ple pivots on the printer (see circled area here).
6. Press and hold down the center tab (see red arrow) which was pre-
viously used to release the print head. Push the print head
upwards so that it snaps into place.
7. Release the center tab and close the Top Cover. Proceed to per-
form a test print to ensure that the print head is connected properly.

CLEANING THE SENSOR
The gap sensor is used to control the positioning of the label. It is a transmissive see-thru sensor that
detects the edge of the label by sensing through the backing paper which is translucent and detecting
the presence of the opaque label.
So when dust, dirt or other foreign matter interferes with the light path of the sensor, erratic label
positioning occurs. The sensor should thus be cleaned regularly, after every two rolls of labels.
1. Turn the printer OFF and remove the power cable.
2. Open the Top Cover.
3. Locate the sensor located next to the yellow screwdriver, near
the left-hand side label guide so that it moves whenever the
Label Guide are adjusted for different media widths.
4. Apply Thermal Print Head Cleaner to a cotton swab.
5. Use the cotton swab to clean any foreign matter from the
exposed surface of the sensor by inserting the cotton tip in the
paper slot and briskly cleaning it with a back and forth motion.
