Overview and Specifications
1.1 Overview
The SATO M-8485Se Service Manual provides information for installing and
maintaining M-8485Se Thermal Transfer Print Engines. Step-by-step
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 SATO M-8485Se Print Engines are designed to be integrated into high
performance on-site labeling systems. All printer parameters are user
programmable, using front panel controls and DIP switches. All popular bar
codes and 14 human-readable fonts, including a vector font, are resident in
memory providing literally thousands of type styles and sizes.
The M-8485Se with its 203 dpi head provides an economical labeling solution
for most applications. It will print on labels from 1 inch wide x .25 inches long
to 5.25 inches wide x 14 inches long using internal memory. Labels up to 5.25
inches wide x 49.2 inches long can be printed by installing a PCMCIA memory
card option. The maximum print width is 5.0 inches.

1.8 Adjusting the Label Sensor
The label gap (transmissive) sensor can be positioned over a limited range. The movable
sensor assembly is mounted on the Label Hold Down and is held in position by two screws.
To adjust the position of the sensor, both screws must be loosened and the sensor moved to
the desired position in the slot and then the screws retightened. Adjustments to compensate
for different liner opacity are done with the LCD panel.

The M-8485Se printers can position labels using either a label gap (transmissive) or an "EyeMark" (reflective) sensor. The sensor used is selected by DSW2-2. The gap sensor position
can be adjusted over a limited range. In addition, the signals from the sensors can be
adjusted using the LCD panel to compensate for different liner opacities and/or "Eye-Mark"
reflectance values.

1.9 Ribbon
Use only SATO thermal transfer ribbons which were formulated expressly for use in all
SATO printers. Use of other than approved ribbons may result unsatisfactory print quality
and/or damage to the print head and may void your warranty.
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 module, 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.
• Excessive warm or cold temperatures can cause electrical problems within the printer.

Software Default Settings - The printer stores any software settings upon receipt
from the host and uses them until they are again changed by receipt of a command
containing a new setting. These settings are stored in non-volatile memory and are
not affected by powering the printer off. The printer may be reset to use the default
software settings by depressing the LINE and FEED keys simultaneously while
powering the printer on. You will be asked to confirm that you want the printer
default settings by selecting either YES or NO by using the LINE key to step the
underline cursor to the desired setting. If you select YES and press the FEED key, the
following default configuration will be stored:

2.3 Potentiometer Adjustments
Pitch
After the pitch has been set with the LCD Control Panel, it is sometimes desirable to make
minor adjustments. This can be done using the PITCH potentiometer on the front panel.
This potentiometer is set at the factory so that it has a range of +/-3.75mm. The midpoint
setting should have no effect on the pitch. Turning the potentiometer all the way clockwise
should move the print position 3.75mm up towards the top edge of the label. turning it all
the way counterclockwise should move the print position down 3.75mm.
STEP

Potentiometer Adjustments
Backfeed Offset
When a label is printed it must be correctly positioned for dispensing and application. The
Backfeed adjustment is used to position the label so that it is fully dispensed and ready for
application. It may then be necessary to reposition the next label before printing. The
Backfeed (repositioning of the label) operation is enabled if DSW3-4 is in the Off position. If
Backfeed is enabled, placing DSW3-1 in the Off position will cause the backfeed operation to
be performed immediately before each label is printed. If DSW3-1 in in the On position, the
backfeed operation is performed as soon as the dispensed label has been printed and taken
from the printer.
The amount of backfeed is controlled by the OFFSET potentiometer on the DIP Switch Panel
inside the cover. When turned all the way clockwise, the amount of backfeed is +3.75mm
and when turned all the way counterclockwise the amount of backfeed is -3.75.
STEP

Display
This potentiometer is used to adjust the contrast of the LCD display for optimum viewing
under various lighting conditions.
Print
This PRINT potentiometer is used to adjust the duration the elements are energized for
printing. It provides a continuous range of adjustment. Maximum print darkness is obtained
by turning the potentiometer all the way clockwise. Turning the potentiometer all the way
counterclockwise will give the lightest print.
NOTE: The PRINT potentiometer adjustment will affect the darkness in all the
command code speed and darkness ranges.

2.4 LCD Panel Printer Configuration
The LCD Panel is used by the operator in conjunction with the LINE and FEED switches
to manually enter printer configuration settings. Many of the settings can also be
controlled via software commands and in the case of conflict between software and
control panel settings, the printer will always use the last valid setting. If you load a
label job that includes software settings and then enter a new setting via the LCD Panel,
the manually set values will be used by the printer. If you set the values manually and
then download a job with software settings, the software settings will be used.
There are elleven modes of operation. To enter the desired mode, the KEY SEQUENCE
combination listed in the table below must be performed. The initial LCD display
message is shown for each mode.

v:+0000 H:+0000
Vertical Offset is the distance down from the leading edge (the edge of the label that
comes out of the printer first) to the first vertical print position. A positive setting
moves the first print position down the length of the label while making it negative
moves it up the length of the label.
Horizontal Offset is the distance that the label image is shifted either to the right or left
on the label. For a positive setting the image is shifted to the left (towards the inside
edge of the label for a right-hand printer). For a negative setting the image the image is
shifted to the right (towards the outside edge of the label). This setting changes the base
reference point for all subsequent label jobs. The effect is identical to the <ESC>A3
Base Reference point command. Since the printer moves the label in discrete steps
equal to the size of the print dot, the units of measure for Vertical and Horizontal Offset
distance is dots. The maximum values that can be set for each is +/-800.

The M-8485Se printers determine the location of the leading edge of the label by
measuring the difference between light levels when it sees either a label edge or a black
"EYE" mark. This adjustment allows you to manually set the threshold voltage level
between the maximum and minimum light levels. DIP switch DSW2-2 selects the sensor
type. If DSW2-2 is in the OFF position, the setting will be for a See-Thru (or Gap) sensor
and the LCD will display "GAP" on the top line along with the current setting. If DSW2-2 is
in the ON position, the LCD will display "EYE" on the top line with its current setting. If
the value entered for the bottom line setting is "0.0V", then the printer will automatically
calculate the setting when the first label is fed after the printer is powered on or the head
is closed. There are some instances where the automatically calculated value must be
adjusted to ensure reliable label feeding, such as when the backing opacity or the
reflectance of the "EYE" mark varies significantly within a roll of labels or between label
rolls. In these instances the value should be set using the following procedures.

GAP - When setting the "GAP" threshold, the voltage shown on the top line of the display
must be measured with nothing but the backing in the sensor and then again with a label
still attached to the backing. The formula to be used for setting the threshold is:
(High Voltage Level + Low Voltage Level) x 0.5 = Start Value
STEP
PROCEDURE
1.
Insert a label still attached to the backing into the sensor and close the Label
Hold-Down. Record the voltage shown on the top line of the LCD panel.
This line should have the message "GAP" on the top line (DIP switch DSW2-2
= OFF). Make sure the label is all the way under the sensor.
2.
Strip the label from the backing and insert the backing strip under the sensor
and close the Label Lid. Record the voltage shown on the top line of the LCD
panel. The voltage ranges measured should be within the following range.
Backing without label = 0.3 - 0.5V
Backing with label = 1.0V >/- the low value
If the measured values are outside this range, you may have trouble finding a
value that will work properly under all conditions. If this is the case, a
higher quality label may be needed to get adequate performance or see
Section 4.3.
3.
Calculate the starting point voltage using the formula.
4.
Use the LINE key to step the counter to the desired setting. The display will
increment one step for each time the LINE key is pressed. If the LINE key is
held down for more than two seconds, it will automatically go into the fast
scroll mode. The reading will advance to a setting of 3.3 (the maximum
voltage) after which it will automatically wrap and start at "0.0" again. If a
value of "0.0" is set, the printer will automatically set the level each time the
printer is powered on with labels loaded or the head is closed.
5.
Once the setting is correct, pressing the FEED key will accept the setting and
advance to the Online Feed display.

This section presents the interface specifications for the M-8485Se printer.
These specifications include detailed information on how to properly
interface your printer with your host system.
M-8485Se printers utilize a Plug-In Interface Module for maximum printer
configuration flexibility.

3.2 Interface Types
The parallel interface for the M-8485Se Printer is a high speed, bi-directional parallel
interface that conforms to the IEEE 1284 specification. (ECP mode on some computers).
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.

Section 3. Interface Specifications
Interface Types
In order to provide flexibility in communicating with a variety of host computer systems,
M-8485Se printers use a Plug-In Interface Module. The IEEE1284 Interface module is
shipped with the printer unless another interface type is specified at the time of the order.
The other interfaces available are a high speed (to 57.6K bps) serial interface, an Ethernet
interface or an optional Universal Serial Bus (USB) interface.
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.
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.

3.3 The Receive Buffer
The M-8485Se 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 so 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.
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 XOn status if using X-On/X-Off), meaning the printer is ready to
receive data. When the receive buffer is holding 2.0MB of data (1MB 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"

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
bytes of data are being held (2.0MB bytes 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, ribbon out) will cause the printer to go busy

printer will also be busy if taken offline from the front panel.
3.4 IEEE 1284 Parallel Interface
The parallel interface for the M-8485Se printer is a Plug-In Interface Module that can
be installed by the user. It 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.

SIGNAL DESCRIPTION
FG (Frame Ground)
TD (Transmit Data) - Data from the printer to the host computer.
Sends X-On/X-Off characters or status data (Bi-Directional protocol).
RD (Receive Data) - Data to the printer from the host computer.
To Host
RTS (Request to Send) - Used with Ready/Busy flow control to
indicate an error condition. RTS is high and remains high unless the
print head is open (in this case, RTS would return to the high state
after the print head is closed and the printer is placed back on-line)
or an error condition occurs during printing (e.g. label out).
To Printer
CTS (Clear to Send) - When this line is high, the printer assumes
that data is ready to be transmitted. The printer will not receive data
when this line is low. If this line is not being used, it should be tied
high (to pin 4).
6
To Printer
DSR (Data Set Ready) - When this line is high, the printer will be
ready to receive data. If this line is not being used, it should be tied
high (to pin 20).
7
Reference
SG (Signal Ground)

20
To Host
DTR (Data Terminal Ready) - This signal applies to Ready/Busy flow
control. The printer is ready to receive data when this pin is high. It
goes low when the printer is off-line either manually or due to an
error condition, and while printing in the Single Job Buffer mode. It
will also go low when the data in the buffer reaches the Buffer Near
Full level.
Ready/Busy Flow Control
Ready/Busy is the hardware flow control for the serial interface on the M-8485Se 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.
Page 3-8
SATO M-8485Se Standard Print Engine
Service Manual
PN 9001080
Rev. A
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 it sends an XOff 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, ribbon out), the printer sends an X-Off as
soon as an error condition is 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.

NOTE: All characters are in ASCII.
3.6 Universal Serial Bus (USB) Interface
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 on your PC and the PC must be configured to support USB
peripherals using Windows 98. 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.

3.8 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 4 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 Bi-Com 4 mode, the host 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 25 bytes of status
information bounded by an STX/ETX pair. The Bi-Com protocol works only in the MultiJob 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>
Page 3-10
SATO M-8485Se Standard Print Engine
Service Manual
PN 9001080
Rev. A
Section 3. Interface Specifications
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 the Job Name is less than 16 characters, the
field will be padded with leading zeroes.
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 and 16 byte Job Name.
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
any 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 (16 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 Bi-Com 3 ENQ/ACK/NAK protocol selected via DSW2-8 and
DSW1-7/8 (on the RS232 Interface module). 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.

NOTE: The signals on pins 1, 3, 4, 6, 9 and 10 each have an open collector output. These pins normally
measure +.07V maximum when a true condition exists. If a false condition occurs, the voltage will drop to
0V. To achieve a signal level of +5V, you must add a 330 ohm, ¼ W pull-up resistor between the open
collector output pin and Vcc (pin 13) as illustrated. This will provide a signal level of +5V for a true
condition and 0V when a false condition exists. The maximum voltage that can be applied to these pins is
+50V and the maximum current they can sink is 500 milliamps.

4.1 Overview
This chapter describes how to check the M-8485Se printer 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 Service Board. 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:
• DC Power Voltage
• Label Pitch Sensor
• Ribbon Sensor
• Pitch Offset
• Label Positions
• Print Darkness
• Calendar Clock Setting
Checks and adjustments in this section require standard metric tools.
Other equipment is listed where needed.

8.1 Overview
This section has been devised to help you if you are unable to produce output on the
M-8485Se printer. Use this section to make sure the basics have been checked before
deciding you are unable to proceed further. This section covers the following:
To help you, this section has been divided into the following parts.
• Initial Checklist
• IEEE1284 Parallel Interface
• RS232C Serial Interface
• Universal Serial Bus Interface
• LAN Ethernet Interface
• Error Signals
• Troubleshooting Tables
• Head Pattern Examples
Rev. A
SATO M-8485Se Standard Print Engine
Service Manual
Page 8-1
Section 8. Troubleshooting
8.2 Initial Check List
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 or the Label Hold-Down is not closed and latched in position.
3. Are the Label and Ribbon lights on the front panel Off? If these lights are On, the labels
or ribbons may be incorrectly loaded.
8.3 The IEEE1284 Parallel Interface
1. Is the IEEE1284 printer cable connected securely to your parallel port (DB25S Female) on
the PC and to the Centronics 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 IEEE1284 specifications? If it does not and
you are connected to an IEEE1284 or ECP parallel port on the computer, the printer may
not be able to communicate correctly.
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 IEEE1284 Interface Module installed in the printer? Older versions of the Parallel
Interface module will not work correctly in the M-8485Se printers.
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.
6. 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 your data stream for some of the basics. Is your job framed as follows:
<ESC>A—Data—<ESC>Z
b. Verify that you've included all required parameters in the data stream.
Page 8-2

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.
•
Your protocol codes are set for Standard or Non-Standard and data stream is
consistent with these.
7. 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 Mode in Section 8.10.
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.
8. While checking the Hex Dump printout, look for 0DH 0AH (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 0DH 0AH 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 The RS232C (Serial) Interface
1. Is the RS232C Serial cable connected securely to your serial port on the PC (DB-25S Male)
and to the RS232C connector on the 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 Module installed in the printer?
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 on the
LCD 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, print a Configuration Test Label. It
will list all of the current printer configuration settings.
6. If you are still unable to get printer output, try the Hex Dump as described Step 7 under
IEEE1284 Parallel Interface Troubleshooting. In this case, the printer monitors the RS232C
interface for incoming data.
7. From the Hex Dump, if you are seeing extra ,0)0 (CR and LF) characters, and are using
BASIC, refer to the beginning of the Command Code section in the Operator and Technical
Reference Manual.
8.5 The Universal Serial BUS (USB)
If nothing prints when doing a test print you will need to verify that the device drivers have been
successfully installed by doing the following:
1. Click on Start, then Settings and then Control Panel.
2. Within the new Window, you should have an Icon listed as System. Double click on this.
3. Click on the Device Manager tab.
4. Make sure that the View Device by type is checked. Scroll down until you get to
SATO-USB device.
5. Verify that it does not have any errors next to it. If it shows an error, remove the device and then
reinstall it.
6. Reboot the PC and the Printer.
7. Consult the Windows 98 Troubleshooting guide or contact technical support for further assistance.

8.6 The LAN Ethernet Interface
Printer Does Not Come UP Ready
If you cannot print to the print server after you install it, check the following:
1. Make sure that the printer is powered on, that all cables are securely plugged in, and that the
printer is on-line.
2. If possible, connect a terminal to the serial port. If you see the boot prompt, the print server
firmware has not been loaded properly. If reloading does not fix the problem, try setting
switch 1 to ON (factory defaults) and powering the print server off and then on again. If the
problem persists, the product may be defective.
Installation Problems (Printer Comes Up Ready but You Cannot Print)
If the printer starts up OK but you cannot print, the problem could be one of the following:
• There is a problem with the interface between the print server and the printer.
• There is a problem with the network connection or cabling.
• There is a queue setup problem, a print server setup problem, or other protocol-related
problem.
Checking the Interface between the Print Server and the Printer
First make sure that the cable between the print server and the printer is securely plugged in at
both sides. Then:
Wait about two minutes after the printer is powered on and then run a printer self-test (see
Section 2 Configuration for information on how to run the self test).
• If the self-test does not print, then there is probably a hardware problem. Double check the
connections.
• In some rare instances, disabling NBUF with the command SET PORT P1 NBUF DISABLED
will solve port compatibility issues.
Checking the Network Connection and Cabling
If the self-test page prints but you cannot print documents, first check the network connection
and cabling.
1.
If you are connecting to a 10baseT network, verify that the OK LED is on. If the appropriate
LEDs are not on, there is probably a bad 10baseT or 100baseTX cable or the hub port is bad.
If possible, try a different cable and hub port, or try connecting a different device (such as a
PC) to the cable.
2.
If you are using a repeater or hub, make sure that SQE (heartbeat) is turned off at the hub
(this is the default setting for most hubs). Also, if you have a hub or multiport repeater,
verify that the hub or repeater port is good by trying the print server on a different port.

3.
If you have a bridge or router located between the print server and the host computer,
make sure that the device is set up to allow the print server to send and receive data from
the host. For example, a bridge can be set up to only allow certain types of Ethernet
addresses to pass through (a process known as filtering); therefore, such a bridge must be
configured to allow print server addresses. Likewise, a router can be set up to pass only
certain protocols, so be sure that the desired protocol can be passed through to the print
server. In the case of routers, also make sure that the protocol is routable (LAT, NetBEUI,
and DLC/LLC are not routable).
4.
Make sure that you are not trying to perform an illegal operation, such as attempting to
print a label larger than the printer can handle.
5.
Check the individual protocol troubleshooting sections in this chapter for additional causes
of intermittent printer problems.
Intermittent Problems
If the print server and the printer start up OK, but you intermittently have problems printing,
check the following:
1.
Excessive NetWare polling can be a big cause of intermittent problems. Make sure that you
have only enabled the NetWare file servers that you need for printing (do a SHOW
NETWARE command from the print server console to see the enabled file servers). If you
have V3.21 or earlier firmware, make sure that NetWare polling is disabled by using the
console command SET NETWARE RANGE 0. If you are not using NetWare, you can
disable NetWare entirely with the command SET NETWARE DISABLED.
2.
Check the individual protocol troubleshooting sections in this chapter for additional causes
of intermittent printer problems.
TCP/IP Troubleshooting
If you are using TCP/IP and cannot print to the print server and you have checked the hardware
and network as described in the previous steps, then check the following, (Note that it is always a
good idea to try creating another print queue to eliminate the possibility of setup errors):
1.
The problem may be the result of mismatched or duplicate IP addresses. Verify that the IP
address is correctly loaded into the XCD print server (via the self-test page or through the
remote console) and make sure that no other nodes on the network have this address,
(Duplicate IP addresses are the biggest cause of TCP/IP printing problems). If the address
is not correct, then check whether the loading procedure was properly executed.
2.
If you used NCP, XCONFIG, or ccr to enter the IP address, make sure that you exited the
remote console properly with a CTRL-D or EXIT command.
3.
If you used rarp, make sure that you started the rarp daemon using the rarpd, rarped -a,
in.rarpd -a or equivalent command. Verify that the /etc/ethers file contains the correct
Ethernet address and that the print server name matches the name in the /etc/hosts file.
4.
If you used bootp, make sure that bootp is enabled (i.e., the "#" is removed from the bootp
entry) in the /etc/inetd.conf file. Verify that /etc/bootptab file is correctly configured.

Section 8. Troubleshooting
The LAN Ethernet Interface (Cont)
5.
Also verify that the host computer and the print server are either on the same subnet (for
example, if the print server has a subnet mask of 255.255.255.0, the host must have the
same subnet mask) or that the router is properly configured to pass data between the two
devices.
6.
Make sure that the /etc/printcap file (if applicable) is typed in correctly. In particular,
look for missing ":" and "\" characters, because a small error anywhere in the file can
have major consequences. Also check the /usr/spool directory to make sure that you
have created a valid spool directory.
7.
If you are using a Berkeley-based UNIX, make sure that the daemon is started on
Berkeley based systems with the command lpc start printer, where printer is the name of
the local print queue.
8.
If you are using an AT&T-based UNIX, make sure the printer is enabled (enable printer,
where printer is the name of the local print queue).
9.
Make sure that the lpr/lpd remote line printer service are running on the host computer
(refer to your host computer documentation for information on how to do this).
10. If you cannot print from DEC TCP/IP Services for VMS (UCX), make sure that you have
version 2.0B or later of this software, because earlier versions will not work with the print
servers.
11. If jobs are run together or do not eject from the printer, try setting the service (remote
printer) with EOT set to the appropriate printer reset string. This string is number 4
(%-12345X) for all newer HP printers. For example:
SET SERVICE BINARY_P1 EOT 4
12. If the lines of a text file are staggered, make sure that you have specified a remote printer
(rp) name of TEXT in your /etc/printcap file.
13. If you are having trouble printing long jobs (over 1MB) add the line mx#0 to your /etc/
printcap file entry.
14. If you are using the raw TCP port and are experiencing intermittent queue stalling
problems, make sure that queueing is enabled on the service (do a SHOW SERVICE
command from the remote console and note if "Q" is listed in the OPT column for the
desired service). If it is not, enable queueing with the command SET SERVICE
servicename QUE ENA command.
15. If the wrong IP address is loaded, check your network for file servers that have DHCP,
BOOTP, or rarp enabled and make sure that these file servers are not set up to load IP
addresses into the print server. Also make sure that you do not use the command SET IP
BOOT 0 to disable TCP/IP broadcasts; instead, you should use the command SET IP
METHOD STATIC (unpredictable results will occur otherwise).

16. If you have problems with queues locking up when the active print job is deleted, try
setting the IP timeout to one minute with the console command SET IP TIMEOUT 1.
17. There were a number lpr/lpd-related problems fixed the V3.46 firmware. Therefore, if you
are experiencing intermittent queue problems and you have an older version of firmware,
SATO recommends you upgrade to 3.46 or later.
Netware Troubleshooting
If you cannot print from NetWare and you have checked the hardware and network as described
in the previous steps, first verify that the print server is attached to the server queue by going to
PCONSOLE, selecting PRINT QUEUE INFORMATION, and then CURRENTLY ATTACHED
SERVERS. If the print server does not appear in the list of attached servers, then check the
following. (Note it is always a good idea to try deleting and recreating the print server and
creating a new print queue in order to eliminate the possibility of setup errors.)
1.
If you cannot create a print queue, make sure you have sufficient NetWare privileges. With
NetWare 3.12 and earlier, you MUST be logged in as SUPERVISOR (not someone with
Supervisor privileges). If you are having problems creating queues with NetWare 4.xx and
later, try logging in as ADMIN. Also make sure you are not trying to run XAdmin32 with
Microsoft NetWare client (you must use the Novell 32-bit client).
2.
If you changed the login password, you must change the password in both the print server
(using the SET NETWARE PASSWORD command) and in the file server (using the
PCONSOLE Print Server Information Change Password command).
3.
Make sure you have enabled at least one NetWare file server using the SET NET WARE
SERVER servername ENABLED command.
4.
Have you exceeded your NetWare user limit?
5.
If you have V3.00 or earlier firmware, make sure you enable either 802.3 or Ethernet II
frames on your file server, particularly if you have a NetWare 3.12 or 4.xx file server (since
these NetWare versions default to 802.2)since these versions of firmware do not support
802.2 or SNAP frames. Also, if you are using NetWare 4.xx make sure you have enabled
binary emulation on the file server.
6.
Make sure the print server name you used in PCONSOLE exactly matches the name that is
configured in the print server and make sure it is defined as a Queue Server for the print
queue.
7.
If you are running both 802.3 and Ethernet II frames on different file servers on your
network, there is a possibility that the print server may not make a connection to the
desired file server. Try forcing the frame type to the desired one using the SET NETWARE
FRAME command from the print server remote console.
8.
If you are losing portions of your print job and you are using the DOS NetWare drivers, try
setting the TIMEOUT parameter in your CAPTURE statement to a higher value, (at least 50
seconds for Windows).

The LAN Ethernet Interface (Cont)
Windows NT/LAN Server Troubleshooting
If you are having trouble printing with Windows NT or LAN Server, check the following:
1.
Make sure you can print from the print server using DOS or OS/2 comand PRINT ipaddress,
where ipaddress is the IP address of the print server. If you cannot print from the print
server you will not be able to print.
2.
Make sure TCP/IP and lpr printing are installed and running on the Windows NT system or
the LAN Server file server.
3.
If you are having problems printing to the print server from a client PC that is connected to a
Windows NTAS or LAN Server, verify that you can print a job directly from the DOS or OS/2
prompt on the file server. If you can print from the file server but not from the client, then
the problem is probably with the NetBEUI communications rather than with the TCP/IP link
to the print server. Check your file server network setup (for example, make sure you can
print from the client to other printers on the network).
4.
If you have problems with Windows NT queues locking up when the active print job is
deleted, try setting the IP timeout to one minute with the console command SET IP
TIMEOUT 1.
5.
There were a number of lpr/lpd-related problems fixed in the V3.46 firmware. Therefore, if
you are experiencing intermittent queue problems and you have an older version of
firmware, SATO recommends that you upgrade to 3.46 or later.
Windows 95/98 Peer-to-Peer Troubleshooting
If you are having trouble printing on a Windows 95 Peer to Peer Network, check the following:
1.
If the print server does not show up under JetAdmin on a Windows 95/98 Peer-to-Peer
network, try removing all of the Windows 95 network software from the Network control
panel and then reinstalling them as follows:
• First install the IPX/SPX-Compatible Protocol, the Client for Microsoft Networks,
and the network adapter card driver.
• Restart the system and then add the HP JetAdmin service.
2.
Rev. A
Because of the many changes that have been incorporated in Windows 95/98 Peer-to-Peer
printing since its introduction, it is a good idea to upgrade to the latest version of JetAdmin
(available on the HP web site at http://www.hp.com).
