Unit 1: Introduction
GENERAL DESCRIPTION
SATO’s GL4xxe series printers are competitively-priced 4-inch Direct-Thermal and Thermal Transfer printers
specifically designed for low- to medium-duty manufacturing, supply-chain and retail barcode-printing and RFID
applications. The sturdy aluminium and high impact plastics ensure ruggedness in the harshest environments.
Designed from the outset to be used for RFID applications, the printer comes with all the necessary mounting,
cable routes and space considerations have been designed into the product for easy upgrading to RFID
capabilities. For high quality printing, the printer comes with fixed 203 or 305 dpi print resolutions. Users can also
alter the print resolution by purchasing a suitable print head of the desired resolution. To ensure wide compatibility,
the printer is able to handle numerous industry-standard barcode-printer languages. As well, the series comes
supplied with a wide range of interfaces such as RS232C serial, IEEE1284 high-speed parallel and USB 2.0.
Optionally, users can add 802.11g Wireless LAN and cabled LAN as options.
When connected to a network, GL printers are transformed into remote printers that are controlled by a powerful
printer management utility, SATOnet Connect™. From within a single software console, the printer administrator
can configure and control any networked GL printer even if it is located on the other side of the world.
In addition to switchable print heads, the GL4xxe series also supports options such as the Online Barcode Verifier
(OBV) can be mounted on the printer to evaluate barcode print quality and alert users of failed labels.

Unit 1: Introduction
THEORY OF OPERATION
When activated, media is fed past the print head by an integrated drive train. The drive train is electric, stepper
motor driven and coupled to a gear, pulley, and belt configuration located on the electrical side of the printer’s
center frame. A pulley is concentrically attached to the motor spindle and provides differential torque to a series of
pulleys via three timing belts. These pulleys, with gears concentrically attached, provide movement to the platen
roller spindles and provide media movement through treading contact with the roller.
Two separate stepper motors, transfer torque to the ribbon supply and ribbon rewind spindles by way of a belt
designated for each, and engaged on the opposite end, a pulley for each spindle. The pulleys located on the
printer’s electrical side, are directly attached to gears on the print side. When the ribbon spindles’ gears are
engaged with their respective pulley/gear combo, a separate gear, pulley, and belt configuration transfers torque
from the ribbon rewind spindles to ribbon rollers via a single timing belt located on the printer’s print side. The
ribbon rewind spindle rotates on axis while maintaining its projectory to takeup and rewind used ribbon.
To facilitate removal of the used ribbon material, it is wound onto a cardboard sleeve referred to as a core. The
core is inserted onto the spindle’s boss and rotates in unison. When rewinding is complete, the core is removed
along with the used ribbon material and a replacement core is inserted in its place.
Paper guides within the chassis assembly ensure the media remains properly positioned beneath the print
assembly and is fed unimpeded from the printer’s rear through to the front.
A series of strategically located sensors and switches send signals to the processing unit. Some sensors are two
part consisting of transmitting and receiving components. The transmitting component is mounted opposite of the
receiving component so that media may pass between the two. When present, the media blocks sensor
transmission from reaching the receiver. The processing unit in turn sends response signals to the various features
based on programmed and received data. These signals, are the controlling force of mechanical activities.
The print head, through thermal heat, inductively provided by electrical supply, transfers print images onto the
media as it passes. The print image may be manifested through either a direct process initiated through a chemical
reaction to the heat from within the label media or transferred from the ink coated ribbon stock.
Predetermined voltage supply of alternating current, from an independent source, is required for proper function.
The printer’s integrated power panel transforms the supplied voltage to direct current which is mediated to the
various circuitry. This circuitry is comprised of properly positioned transformers, relays, diodes, resistors, and chips
which sends, receives, and processes communication data throughout the system.

Unit 3: Interface Specifications
IEEE1284 PARALLEL INTERFACE
The parallel interface is a standard connection in the GL4xxe series printers. It conforms to IEEE1284
specifications. It supports three operating modes, which are determined by negotiation between the printer and the
host.
Compatibility Mode: This mode provides compatibility with Centronics-like host I/O. Data is transferred from the
host to the printer in 8-bit bytes over the data lines. Compatibility Mode can be combined with Nibble and Byte
Modes to provide bidirectional communication.
Nibble Mode: Eight bits equals one byte. When a byte of data is sent to the printer, the eight bits are sent over
eight data lines. Some devices cannot send data over their eight data lines. To bypass this, the IEEE 1284 permits
data to be sent as half a byte over four status lines. (Half a byte equals one nibble.) Two sequential four-bit nibbles
are sent over the lines. Data is transferred from printer to host in four-bit nibbles over the status lines, and the host
controls the transmission.
Byte Mode: The printer and host send data to each other along eight data lines (one bit per line). If bidirectional
communication is supported by the printer and the host, the host will take control of the data transfer.

Program Download
Normally the Host communicates with the printer’s USB port with a Windows Driver. The Windows Driver cannot be used to
transfer binary data to the printer, such as the data contained in a Program Download. To do a Program Download through the
USB Port perform the following steps:
1. Make the printer sharable on the Host PC. This is done through the Printer Setting Window on the PC. Make note of the
Printers Shared name.
2. Open a Dos Window on the PC. At the command prompt type: NET USE LPT1\\COMP_NAME\Printers_Shared_Name /
Persistent:YES This command should be all on the same line. It redirects output on LPT1 to the shared printer.
COMP_NAME is the computer name found on the system settings. Printers_Shared_Name is the shared name found in the
printer Properties\Sharing tab.
3. To check status of connection type: Net View \\COMP_NAME
COMP_NAME is the computer name found on the system settings. Now the printer is ready.
4. Use the COPY command to send the program file to the printer. Type: COPY /b <File Name> lpt1:
5. To stop using LPT1 for USB, type: NET USE LPT1 /DELETE

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).

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.

while printing.
The speed may be adjusted in increments of 1 ips with a range from 1 to 10 ips.
The factory default is 4 ips.
Print Darkness

Specifies the level of thermal energy provided from the print head to affect print darkness. The
print darkness setting needed is dependent on the type of ribbon and media installed for use and
also relative to print speed.
The adjustment range is from -15 to +15. The factory default is -3.
This setting vertically adjusts where the printer begins printing relative to top-of-form.

00.0 mm*
DESCRIPTION
Specifies the distance to advance or retract the print image on the label to determine its vertical
positioning. The actual image height is not affected by this adjustment, only its location.
The factory default is -1.00 inches with a range of 6.00 inches. A negative value (-) retracts the
image and a positive value (+) advances the image placement on the label.
Specifies the lateral distance to move the print image on the label to determine its horizontal
positioning. The actual image width is not affected by this adjustment, only its location.
Hor Print Offset
00.0 mm*
The factory default is 0.00 inches with a range from -1.00 inch to +1.00 inch. A negative value (-)
moves the image closer to the printer’s center frame and a positive value (+) moves the image
from the printer’s center frame.
Typically specifies the physical label length of the media installed. However, the type of media in
addition to its size it a determinant.
• Die-Cut Labels - the measurable length of the removable label. Does not include the liner
material or gap.
Label Length
152 mm*
• Tag Stock w/ notices or holes - the measurable length is from the trailing edge of one notch
or hole to the leading edge of the next notch or hole.
• Tag Stock w/ black marks on underside - the measurable length from the leading edge of
one black mark to the leading edge of the next black mark.
• Continuous Media w/o indicators - the measurable length depends upon the image size.
The allowable label length is from 0.1 to 0.99 inches (2.5 - 2514.6mm). The factory default is 6
inches. The label length allowable is dependent on the label’s width and the print head resolution
in use.
Label Width
Specifies the physical width of the print image. The allowable range is 0.1 to 4.1 inches (2.5 104mm).

C128 Mode Switch
Allows fine adjustment of resolution used to scale page elements/coordinates. In cases where the
printed label length is incorrect, the vertical resolution value used for calculations can be fine
adjusted by this menu between -100 and +100.
Negative values result in a lower DPI value and thusly a longer label. Positive values result in a
higher DPI value resulting in a shorter label. This adjustment does not affect the size of images
and downloaded bitmap fonts.
Allows compatibility with older SATO printer models. By selecting ‘Automatic’ enables the printer
to encode C128 bar code data using automatic mode switching. This action generally results in
smaller barcodes.

activity.
Slew Speed Ctrl
• Automatic - always the same as the print speed.
Automatic*
• Manual - allows the slew speed to be set. Selecting this option brings up another menu that
allows a speed range from 2 to 10 ips. The factory default is 6 ips, but the maximum slew
speed is also determined by the printer model.
Determines basic print image orientation.
Print Direction
Head First*
• Head First - the edge of the image that has been determined to be the top will be printed
first. In the case of a portrait, the head will print and exit the printer first.
• Foot First - the edge of the image that has been determined to be the bottom will be printed
first. In the case of a portrait, the head will be printed and exit the printer last.
Note: This feature will not change the orientation of any test patterns in the DIAGNOSTIC mode.
Tear-Off Time
01.0 seconds*
Allows specification of the number of seconds after the buffer is empty that the printer will wait
before it advances media to the tear bar position. This is applicable when Media Handling is set
to Tear-Off Strip or Continuous mode and Continuous mode is set Tear-strip Full.
The allowed range is .1 to 60.0 seconds and the factory default is 1.0 seconds.
Allows a label to be detected at the tear bar for the Peel-Off Media mode.
Label Missing
Fault Disable*
• Fault Disable - factory default. The printer does not generate a fault condition if a missing
label is encountered.
• Fault Enable - the printer generates a fault condition if a missing label is encountered.
Determines how the printer handles images that are too large for one physical page length when
using gap or black mark media.
• Enable - factory default. When the user selected page length is greater than the physical
page length, the printer clips the excess data to fit the physical page and the excess data is
lost. The media sensor consequently looks for the gap, notch, hole, or black mark and when
detected, uses it as the top-of-form position for the next label. Any remaining data is clipped
from the label being printed.
Clip Page
Enable*
• Disable - when the user selected page length is greater than the physical page length
dictated by the gap, notch, hole, or black mark on media, the printer continues to print the
remaining excess data onto the next physical page. The media sensor looks for the gap,
notch, hole, or black mark only after the media has advanced the distance specified by the
label length value in the Media Setup menu or by the Host Forms Length value sent by via
the software. Any gaps, notches, holes, or black marks that exist prior to reaching the Label
Length or Host Forms Length are ignored.
Note: When Disable is selected, media sensing reliability can be improved, but the correct label
length value must be entered. If the value is too long, the printer will ignore the actual gap or mark
it needs to detect. When gap sensing is used, the Label Length value is equal to the physical
length of a die-cut or removable label. When eye-mark sensing is used, the Label Length value is
the physical distance from the leading edge of one eye-mark to the leading edge of the next.
Fault Reprint
Enable*
This menu option determines how the printer handles data that was printing when an error
occurred.
• Disable - factory default. Will not reprint a label affected by an error condition.

Note: When Set Label Length = Automatic and the label sensor is set to Gap, the printer will
subtract the Gap Length value (in the Sensor Setup menu of the Advanced Mode) from the
Sensed Distance value obtained when the Auto or Manual Calibrate was performed. Setting the
label length to ‘Automatic’ sets the ‘Use Label Length’ menu to ‘Disable’ in the Sensor Setup
menu of the Advanced Mode.
TOF Detect Fault

TOF Adjust
10.1 mm*
This option sets the distance from the top-of-form (TOF) that is left blank (unprinted) after a label
has been removed in Tear-Off Strip. Printing normally starts at top-of-form, but when enabled, the
print start position can be adjusted from 0.00 to 0.40 inches from top-of-form in increments of
0.01 inches.
This adjustment is useful if a die-cut label sticks to the platen because of jagged edges created
by poor label removal using the tear bar. By controlling how much blank space there is from topof-form, the amount of media called back after being torn off can be controlled.

Sensed Distance
This value represents in inches, the distance that was sensed between the top-of-form of one
label to the top-of-form of the next label. With gapped media loaded, the distance equals the
physical label length plus one gap, notch, or hole (trailing edge to trailing edge).
Sensed Distance
XX.X mm
GL4xxe Series Service Manual
With eye-mark media loaded, the distance equals the leading edge of one eye-mark to the
leading edge of the next eye-mark. This value is automatically determined only after successful
completion of Auto or Manual Calibrate and cannot be manually changed. The factory default is
0.00 inches.

MENU
Gap/Mark Thresh
DESCRIPTION
This menu sets a value that when exceeded by the output of the media sensor, is recognized by
the printer as a gap or eye-mark. When Auto or Manual Paper Calibrate is performed, the value
displayed is equal to the gap/eye-mark threshold value set by this procedure. If running the
procedure does not provide a reliable top-of-form detection (e.g., when using unusual media), the
Gap/Mark Thresh value can be manually set to the desired value.
XXX*
The factory default is 171 with a range of 000 to 255.
Note: If the Gap/Mark Sensor (in ADVANCED MODE) is set for gap sensing, the factory default is
140. The factory default is 75 for eye-mark sensing.
Paper Out Thresh
XXX*
This menu allows selection of a value that when exceeded by the output of the media sensor, is
recognized by the printer as a paper-out condition. When Auto or Manual calibrate is performed,
the value displayed is equal to the paper-out threshold value set by this procedure. If running this
procedure does not provide a reliable paper-out detection (e.g., when using non-standard media),
the Paper Out Thres value can be manually set to the desired value.
The factory default is 171 with a range of 000 to 255.
Note: If the Gap/Mark Sensor (in ADVANCED MODE) is set for gap sensing, the factory default is
160. The factory default is 150 for eye-mark sensing.

This menu provides another method of improving the printer’s media sensing and is only used
when Auto Calibrate has failed or the Gap/Mark Threshold or Paper Out Threshold values
derived from Auto Calibrate do not improve the media sensors’ gap or eye-mark sensing
capability.
Is the final stage of the Run Manual Cal process. The printer uses the statistically derived values,
advances media, stops at the top-of-form position, and momentarily displays the Sensed
Distance. When complete, the Gap/Mark threshold, Paper Out Threshold, and the Sensed
Distance values the printer will use is changed. These value changes take effect immediately
within the current configuration menu.
This menu prompts the operator to manually insert just the liner (paper backing) for Gap sensing,
or the black bar (eye-mark) for Mark sensing. Ensure that either is underneath sensor prior to
pressing the ENTER key of the printer’s operator panel.
Press Enter
LOAD MEDIA
This menu prompts the operator to manually insert both the liner (paper backing) with label for

DESCRIPTION
Head Automatic Calibration. Allows selection of whether the printer performs a media calibration
after a Print head Open fault.
• Enable - factory default. Performs media calibration each time the fault condition is cleared.
• Disable - does not perform media calibration when the fault has been cleared.
SENSOR SETUP
Is the first menu screen of a sub-menu set within Sensor Setup of the ADVANCED MODE. The
sub-menu to follow determines if online automatic calibration will be enabled or disabled.
Online Auto-Cal
Determines if automatic calibration will occur when the printer is online. Will perform Run AutoCal and when complete, the printer will momentarily display the Sensed Distance, then resume
printing any pending jobs.
Online Auto-Cal
Disable*
• Disable - factory default. Automatic calibration will not occur each time the printer is brought
online.
• Enable - automatic calibration will occur each time the printer is brought online.
Note: This feature will not function when there is data in the buffer and when Fault Reprint of the
USER MODE is enabled. This feature must also be enabled prior to printing any data.
Permits automatic compensation for any media imperfections that may affect the sensor’s ability
to read reference indicators.
Gap Windowing
Disable*
Gap Length
3 mm*
• Disable - factory default. When the leading edge of a gap is detected, the printer
continuously looks for the leading edge of the next label and uses it as the top-of-form
position.
• Enable - when the leading edge of a gap is detected, the printer ignores the first 90% of the
gap length value specified in the Gap Length menu option. The result is that cross
perforations or unusual media discrepancies within the gap are filtered out. This allows the
printer to reliably detect the actual leading edge of the next label and use it as the top-of-form
position. With this option, perforations or unusual media discrepancies within the gap can
cause inaccurate top-of-form detection.
Allows the actual length (height) of a gap measured in .01 inch increments to be set. The
allowable range is 0.05 to 1.00 inches.
Note: If an incorrect gap length is set, the image on the label will shift accordingly.
The factory default is 0.12 inches.
Setting determines if a calibration (Run Auto-Cal or Pwr Up Auto-Cal) will be performed while in
the Peel-Off Media Handling mode.
Cal in Peel Mode
Disable*
• Disable - factory default. The printer will not permit calibration and a “CANNOT CALIBRATE/
Disable Peel-Off” message will briefly display. Additionally, if PwrUp Auto-Cal is enabled, the
printer will not perform calibration at power up.
• Enable - Run Auto-Cal can be performed from the operator panel. If the PwrUp Auto-Cal
option is enabled, calibration will be performed at power up.
Minimum Calibrate Delta. Permits the sensor minimum threshold value that is required to detect
the difference between the label and a gap, notch, hole or eye-mark to be changed. This allows
bolder gaps to be used as the top-of-form while intermediate gaps are ignored.
Min Calib Delta
020*
Increasing the value makes the sensors less sensitive to intermediate gaps or noise. Decreasing
the value makes the sensors more sensitive for detecting gaps on low contrast media where
there is little difference between the label and the liner.
The factory default is 012 with a range of 012 to 050.

Unit 5: Printer Configuration
ADVANCED MODE (TABLE 4-3)
MENU
DESCRIPTION
Determines if the Label Length value set in the Media Setup menu is used during Run Auto-Cal.
Run Auto-Cal relies exclusively in its ability to detect varying transitions between labels and gaps,
notches, holes, or eye-marks while advancing media during the calibration process to determine
sensed distance. The amount of media advanced is based on the quantity of transitions detected.
Use Label Length
Disable*
Although the Use Label Length keeps its value (enable/disable) at all times, it will always be
disabled when Set Label Length is set to Automatic. The correct setting will take effect when Set
Label Length is set to manual. Based on the setting on the Label Length menu in the USER
MODE, the Use Label Length menu will be ignored.
• Disable - factory default.
• Enable - the Label Length value set in the USER MODE is used in the calibrate algorithm.
This causes the Run Auto-Cal process to advance media the minimum distance to detect the
true gap, notch, hole, or eye-mark used for top-of-form sensing. This resolves problems
where the sensors may mistake high noise levels or preprinted images within the label as the
reference indicator that could result in a sensed distance value much shorter than the actual
label length. Note that setting a Label Length value less than half the actual label length in
use will result in erroneous sensed distance values when Run Auto-Cal is performed.
This option allows the user to select the optimal threshold range for the label stock in use. The
printer defaults to using a threshold range of 50% of the positive going pulse that represents each
reference indicator detected after doing an Auto or Manual calibrate. the printer then detects
anything within the label with that threshold range as top-of-form.
Threshold Range
50%*
While this range is ideal for most medias, some labels with a preprinted image, liner gap or inlay
can confuse the media sensors causing a false top-of-form detection. In most cases this can be
resolved selecting a higher threshold range so the printer will only trigger on the true top-of-form
position.
Note: A new threshold range will not take effect until an Auto or Manual Calibate is successfully
performed. Run a Media Profile after a Calibrate to visually verify that the new range is the best
possible selection.
The factory default is 50% with an allowable range of 5 to 95% in 5% increments.
Mark Top-Of-Form Detect. Allows selection of the point of measure for the start print position to
be determined.
Mark TOF Detect
Mark Trail Edge*
• Mark Trailing Edge - factory default. Printer adjusts the top-of-form to the label’s trailing
edge.
• Mark Leading Edge - printer adjusts the top-of-form to the label’s leading edge.

SERIAL INTERFACE MODE (TABLE 4-4)
MENU
DESCRIPTION
Allows the serial interface protocol type to be selected to meet host interface requirements.
• DTR - The printer controls the data flow by sending this hardware signal to the host. If there
is enough room in the printer buffer, the printer will send a high signal; if the buffer is full, the
printer will send a low signal. DTR tells the host if it is safe to send more data (if the host
sends data during an unsafe condition, data will be lost). DTR is not available when RS422 is
selected.
• XON/XOFF - factory default. The printer controls the flow of communication from the host by
turning the transmission on and off. In some situations, such as when the buffer is full or the
timing of signals is too slow/fast, the printer will tell the host to stop transmission by sending
an XOFF character. An XOFF character is sent when the quantity of empty bytes in the
buffer is less than or equal to 25 percent of the buffer size. If the host keeps sending data
after an XOFF is sent, the printer firmware will continue to send an XOFF for every 16
characters received. When cleared, the printer will resume receiving data (XON). The data
does not have any End of Text Codes; XON/XOFF is a non-block protocol.
• ETX/ACK - End of Text/Acknowledge. The host controls the flow of communication to the
printer by sending a block of data and ending the block with an End of Text (ETX) signal.
When the printer receives the EXT signal, it acknowledges the ETX, thereby acknowledging
it has received the entire block of data.
Data Protocol
DTR*
• ACK/NAK - Acknowledge/Negative Acknowledge. When the device acknowledges ACK, it
has accepted a transmission. When the device acknowledges NAK, it has not accepted a
transmission.
• Series1 1 Char - The printer controls the flow of communication from the host by turning the
transmission on and off using response characters sent to the host. If the quantity of valid
bytes in the buffer reaches 75 percent of the buffer size, the online or offline and buffer full
response character is sent. If the buffer is completely full, an online or offline buffer full
response is sent every time a character is sent to the host. Whenever the printer state
changes to online or offline, the appropriate response character is sent. If the idle response
option is enabled, the printer will send a response character every two seconds while the
quantity of valid bytes in the buffer is less than 75 percent of the buffer size. If a poll character
is received (configurable from the Poll character xx Hex option on the operator panel from the
Hex 0 through FF), the printer will send a response character in milliseconds later
(configurable from the Poll character xx MS on the operator panel from 0 through 30). This in
milliseconds is called the poll delay. The poll character will be removed from the input data
stream and will not be processed. This may cause problems with the transmission binary
data (e.g., control codes, bit image, etc.). If a poll delay is started due to the receipt of a poll
character and another poll character is received, the second poll character has no effect and
is removed from the input data stream. If a transmission (from buffer full to empty or online to
offline) occurs during a poll delay, the new printer state will be sent at the end of the poll
delay.
• Series1 2 char - This protocol behaves exactly the same as the Series 1 Char except there
is a two-character response to the host.
This menu configures the amount of memory allocated for the serial port buffer. The range is 1 to
16 Kbytes in 1 kbyte increments.
Buffer Size in K

For example, the printer is printing a job from the serial port and then receives a second print job
from the parallel port, the data from the parallel port will trickle bit by bit into the print buffer to
prevent a timeout error from being sent back to the host connected to the parallel port.
The selected value should be less than the host timeout value, but not too much shorter or else
the printer fills up its buffer too fast. This function is applicable for C/T hotport.
the options are 1/4, 1/2, 1, 2, 4, 8, and 16 seconds and Off. The factory default is 1/4.

MENU
DESCRIPTION
Is typically for a line-printer and should not normally be enabled. Is used for legacy applications
which interpret the 8th data bit line as a PI signal.
Data Bit 8
Enable*
• Enable - factory default. The PI line is not passed directly from the host to printer; all 8 bits
are used for data bits. Characters in the Hex 80 to FF range can be accessed.
• Disable - when the PI line is enabled, data bit 8 intentionally indicates PI line status. To use
the PI line, disable data bit 8 and enable the Host PI configuration option (under PI Ignored
option.
Paper Instruction Ignored. This signal is used to control vertical paper motion.
PI Ignored
Enable*
• Enable - factory default. Ignores the PI signal and treats the data as characters or control
codes.
• Disable - causes the printer to interpret the eight data lines as VFU commands when the PI
signal is true.
This parameter must be set to match the response polarity of the host computer.
Data Polarity
• Standard - factory default. Does not expect the host computer to invert data.
Standard*
• Inverted - expects the data received on the data lines from the host computer to be inverted.

computer.
• Standard - factory default. Does not invert the response to the host computer.
• Inverted - inverts the response signal sent to the host computer.
Busy on Strobe
Enable*
The strobe signal tells the printer when to look for data on the data lines. The printer can either be
set to assert a busy signal after each data byte or after the printer’s buffer has filled.
• Enable - factory default. Asserts a busy signal after each character is received.
• Disable - asserts a busy signal only when the print buffers are full.
Specifies whether the data is read on the leading or trailing edge of the data strobe signal.
Latch Data On
The options are Leading and Trailing. Leading is the factory default.
Leading*
Prime Signal

CENTRONICS INTERFACE MODE (TABLE 4-6)
MENU
DESCRIPTION
This feature is used to prevent a host computer from timing out because the parallel interface is
busy for too long.
Auto Trickle
• Enable - factory default. When the printer’s buffers are almost full, the printer begins to trickle
data in from the host (at the rate set in the Trickle Time menu) until the buffers start to empty.
Disable*
• Disable - is not used.
When the printer is printing data from a host and a second job is received by the printer from a
different host, Trickle Time prevents the second host from timing out while waiting for its data to
be printed. In order to support this feature, the port has to be able to accept data from the host
and store it for future use.
For example, the printer is printing a job from the serial port and then receives a second print job
from the parallel port, the data from the parallel port will trickle bit by bit into the print buffer to
prevent a timeout error from being sent back to the host connected to the parallel port.
Trickle Time
1/4 sec*
The selected value should be less than the host timeout value, but not too much shorter or else
the printer fills up its buffer too fast. This function is applicable for C/T hotport.
The options are 1/4, 1/2, 1, 2, 4, 8, and 16 seconds and Off. The factory default is 1/4.
This is the value used by the printer to time out from the current port and check the other selected
Port Types for data print. When the printer has not received data from the host after a certain
period of time, it must timeout in order to service other ports.
Timeout
10 sec.*
The factory default of 10 seconds with an allowable range of 1 to 60 seconds.
When a fault condition occurs in the printer, normally only the active port reports the fault to the
host. When the Report Status menu option is enabled, the port will report any fault even when it is
not the current, active port.
Report Status
Disable*
The options are Disable and Enable. The factory default is Disable.
Allows determination of whether the printer will process data while offline.
Offline Process
• Disable - factory default. The printer does not process parallel/network data while offline.
Disable*
• Enable - the printer continues to process (but not print) the current network/parallel job while
the printer is offline until the printer’s buffer is full.

Label But Size
560K Bytes*
DESCRIPTION
Label Buffer Size. This option allows the label buffer size to be set. The buffer is used to store the
data from ^XA up to ^XZ for command processing. The maximum buffer size cannot exceed the
amount of available memory in the system. If a menu value greater than the amount of memory
available is selected, the menu value will be set to the amount available. To increase the amount
of available memory, increase the Glob Mem Adjust setting in the Printer control menu.
The new buffer size only takes effect upon powering on, so perform a Save Config for the new
setting and select that configuration as the Power-Up.
The allowable range is 160 to 3600 Kbytes, and the factory default is 560 Kbytes.
Determines the method of setting the Label Length.
Host Form Length
Enable*
• Enable - factory default. Label length will be determined by the ^LL command if it is present.
If the ^LL command is not present, it will be based on the Label Length value in the Quick
Setup or Media Control menu.
• Ignore - label length as determined by the ^LL command is ignored.
• Disable - label length will be determined by the Label Length value in the Quick Setup or
Media Control menu.
Left Position
0 dots*
Top Position
0 dots/inch*
The ^LS command specifies a horizontal offset to be added to all label element positions. The
Left Position option displays the value specified by the ^LS command and provides an alternative
method for specifying the horizontal offset.
The factory default is 0 dots.
The value of this option specifies a vertical offset to be added to all label element position in dots
per inch. For example, if the value is 3 and the current form length is 6 inches, then 18 dots will be
added to the element’s vertical position.
The allowable range is -100 to +100 dots/inch, and the factory default is 0 dots/inch.
The ^JM command determines the apparent print resolution of the printed label.
Resolution Mode
• Full - factory default. The output is printed normally. The Resolution mode option displays
and selects the current setting associated wit the ^JM command.
Full*
• Half - if selected by the ^JM command, the printed output of a 300 dpi printer
matches that printed by a 150 dpi printer (half resolution). This essentially doubles
the size of the label image, including label dimensions.
Allows the vertical adjustment feature to be enabled or disabled.
Vertical Adjust
• Disable - factory default. Vertical density adjustment will not take place.
Enable*
• Enable - is active and will use the Vertical Density value selected.
Vertical Density
207 dpi*
If Vertical Adjust is enabled, this option allows to fine tune the vertical print density (in the paper
motion direction) on printers with 203 or 300 dpi print heads. The result is that the vertical position
and height will be changed accordingly. Selecting a greater vertical density value causes the
image to compress or expand vertically on the label.
• 203 DPI - the allowable range is 201 to 220 dpi, and the factory default is 207 dpi.
• 300 DPI - the allowable range is 301 to 330 dpi, and the factory default is 300 dpi.
This command saves the printed label image by name for later recall as part of a label definition
and determines the internal format to be used. The storage location is determined by the option
selected in the Storage Select menu.
IS Label Fmt
List Format*
• List Format - factory default. Used for most applications due to its greater efficiency of data
process.
• Bitmap Format - used in applications that frequently recall the saved label image. Results in
greater print speed.

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.
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.

Unit 6: 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.

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.

ASCII
(American Standard Code for Information Interchange) The most common format for text files
in computers and on the internet. In a ASCII file, each alphabetic, numeric, or special
character is represented with a 7-bit binary number (a string of seven 0s or 1s). 128 possible
characters are defined.
Assembly
The fitting together of parts, components, or sub-assemblies to form a complete unit.
Asynchronous
A type of two-way communication that occurs with a time delay, allowing participants to
respond at their own convenience. This communication allows characters to be sent at
irregular intervals by preceding each character with a start bit and following it with a stop bit.
The timing of the transmission is not determined by the timing of the previous character.
Audible
A sound loud enough to be heard.
Batch
A grouping of anything.
The number of signaling elements that occur each second; or stated differently, the number of
changes to the transmission media per second in a modulated signal.
At slow speeds, one bit of information (signaling element) is encoded in each electrical
change. The baud therefore, indicates the number of bits per second (bps) that are
transmitted.
Baud
Assuming asynchronous communication, which requires 10 bits per character, this translates
to 30 characters per second (cps). For slow rates, (below 1200 baud), the baud can be divided
by 10 to see how many characters per second are sent.
At higher speeds, it is possible to encode more than 1 bit in each electrical change. Thusly,
4800 baud may allow 9600 bits to be sent each second.
At high data transfer speeds, data transmission rates are usually expressed in bits per second
(bps) rather than baud.
Bi-Directional
Capable of operating in two directions along the same plane or medium. In the case a
communication cable or an RFID tag, one that transmits as well as receives, read and written.
Binary
A numeral system that represents numeric values using two symbols, typically 0 and 1. A
binary number can be represented by any sequence of bits (binary digits), which in turn may
be represented by any mechanism capable of being in two mutually exclusive states.
