GENERAL DESCRIPTION  
The M84Pro printer was designed for continuous industrial and commercial applications as self-  
evident with its uncompromising all-metal housing, 203 to 609 dpi resolution, and label width  
capacity up to 5 inches wide.  
This printer uses standard SATO programming language with specific values for print  
resolutions. These values are specified in “dots” and will vary depending upon the printer  
resolution and the amount of memory available for label imaging.  
The M84Pro was designed to be compatible with preceding M-8400 series printers. The main  
difference is how it receives the command sequence and how it responds to certain commands.  
Refer to the Operator and Technical Reference Manuals for additional information.

THEORY OF OPERATION  
When activated, the media and ribbon (where applicable) are fed in conjunction past the print  
head by an integrated drive train. The drive train is electric, stepper motor driven, coupled to a  
gear configuration located on the left side of the printer chassis. Paper guides within the chassis  
assembly ensure that the media remains properly positioned during the printing process and is  
fed unimpeded through the front cover. The exhausted ribbon material is rewound onto a take-up  
core inserted onto drive-train driven spindles.  
A series of strategically located sensors send signals to the processing unit. The processing unit  
in turn sends response signals to the various features based on programmed and received data.  
Correct signals initiate print head activity.

INTERFACE SPECIFICATIONS  
This section presents the interface specifications and include detailed information on how to  
properly interface the printer with the host system.  
INTERFACE TYPES  
The parallel interface is a high speed, bi-directional interface that conforms to the IEEE1284  
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 IEEE1284 signals in the  
interface connection, it will automatically operate in the standard Centronics mode which is much  
slower. To use the IEEE1284 parallel interface to its fullest capability requires that the host also  
have an IEEE1284 compatible interface and that the two be connected with a cable that meets  
the IEEE1284 specification. If either of these two are not present, the data rate is reduced.  
In order to provide flexibility in communicating with a variety of host computer systems all 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  
is a high speed serial interface, an Ethernet interface, wireless Ethernet, or an optional Universal  
Serial Bus (USB) Adapter.  
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  
BY WARRANTY.  
RECEIVE BUFFER  
The printer may be configured to receive a data stream from a singular 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 2.95 MB.

Section 3: Interface Specifications  
MULTIPLE JOB BUFFER  
The printer is able 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. When using the RS232C Serial interface, the multiple 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” (in X-On status if using X-On/X-Off)  
meaning the printer is ready to receive data. When the receive buffer is holding 2.0 MB of data (1  
MB from being full), DTR will go “low” (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 1 MB bytes of data  
are being held (2.0 MB 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 (DTR “low”  
or X-Off) until the problem is corrected and the printer is placed on-line. The printer will also be  
busy if taken off-line from the front panel.

Section 3: Interface Specifications  
IEEE1284 PARALLEL INTERFACE  
The parallel interface for the M-84PRO printers is a Plug-In Interface Module that can be installed  
by the user. It conforms to the IEEE1284 specification. It will automatically detect the IEEE1284  
signals and operate in the high speed mode. If it does not detect the IEEE1284 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 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.

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).  
DSR (Data Set Ready) - When this line is high, the printer will be ready to  
receive data. This line must be high before data is transmitted. If this line is not  
being used, it should be tied high (to pin 20).

* This connection at the host side of the interface would depend upon the pin that is being used as the  
Ready/Busy signal by the driving software. Typically, on a PC, it would be either CTS (pin5) or DSR (pin  
6) on a DB-25 connector.  
READY/BUSY FLOW CONTROL  
Ready/Busy is the hardware flow control method for the serial interface on the M-84PRO  
printers. By raising/lowering the voltage level on Pin 20 of the RS232C 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.  
X-ON/X-OFF FLOW CONTROL  
X-On/X-Off flow control is 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 ìPrinter  
Readyî (X-On =11 hexadecimal) or “Printer Busy” (X-Off = 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 X-Off when the “Buffer Near Full” level is reached and a X-On when the data level of the buffer  
drops below the “Buffer Available” mark. When the printer is taken off-line manually, it transmits  
an X-Off indicating it cannot accept data. When it is placed back on line manually, it sends an X-  
On, indicating it is again available for receipt of data. If an error occurs during printing (paper out,  
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 an 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 constructed in the same way  
as they are for Ready/Busy flow control (<ESC>A . . Job#1 . . <ESC>Z<ESC>A . . Job#n . .  
<ESC>Z). An example of this would be: <ESC>A . . Job#1 . . <ESC>Z. All characters are in  
ASCII.  
UNIVERSAL SERIAL BUS (USB) ADAPTER  
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 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.

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 RS232C

Section 3: Interface Specifications  
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 multiple job buffer mode.  
The status information is defined as follows:  
<STX>{ 2 Byte ID}{1 Status Byte}{6 Byte Label Remaining}{16 Byte Job Name}<ETX>  
STREAM IDENTIFICATION  
ID  
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 information 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  
Job Name  
Six bytes defining the number of labels remaining in the current  
print job. The range is from 000000 to 999999 labels.  
16 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, six “zero” characters (30  
hexadecimal) in the Remaining Labels bytes and the 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 (15 hexadecimal) if an error condition exists.  
PRINT JOB  
Upon receipt of a valid print job (<ESC>A . . . <ESC>Z), an ACK (06 hexadecimal) will be  
returned by the printer if there are no errors and a NAK (16 hexadecimal) if a printer error exists.

Section 3: Interface Specifications  
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.  
Note: To provide compatibility with older SATO printers, the RS232C  
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 software.

PRINTER CONFIGURATION  
This section provides configuration instructions. Figures 10-7 through 10-19 in the Diagrams &  
Schematics section provides diagrams and charts on print operation sequence.  
DIP SWITCH PANELS  
There are two DIP switches (DSW2 and DSW3) located on the front panel under a protective  
cover. A third DIP switch is located on the RS232C Serial Adapter card and is used to set the  
RS232C transmit/receive parameters. Each switch is an eight section on/off toggle type switch.  
The ON position is always oriented upward and consequently, the off is always downward.  
Switch settings are read by the printer electronics during the power up sequence and will not  
become effective until the power is cycled.

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 top panel. This  
potentiometer is set at the factory so that it has a range of +/- 3.75 mm. The midpoint setting  
should have no effect on the pitch. Turning the potentiometer all the way clockwise should move  
the print position 3.75 mm up towards the top edge of the label. Turning it all the way  
counterclockwise should move the print position down 3.75 mm.  
NOTE: Adjusting the PITCH potentiometer will affect the stop position of the  
label.  
1. Press and hold the FEED key while switching the power switch on.  
2. Release the FEED key upon hearing a beep from the printer.  
NOTE: The LCD display will inquire what type of test label is desired.  
3. Use the Cursor keys to step to the desired option and press the ENTER key to select.  
4. Use the Cursor keys to step to the test label size and press the ENTER key to select.  
5. Standby for the printer to begin printing test labels continuously.  
6. Adjust the PITCH potentiometer until the first print position is at the desired location on the  
label.  
NOTE: If the potentiometer does not have enough range, it will be necessary  
to change the pitch setting using the front panel display.  
7. Press the FEED key to cease printing when complete.  
8. Power the printer off and then back on, to exit the test label mode.

Section 5: Printer Configuration  
BACKFEED OFFSET  
When a label is printed it must be correctly positioned for dispensing and application. Thusly, the  
printer advances the label stock sufficiently for the printed label to be dispensed. After the label  
has been removed for application, the label stock must be withdrawn back into label printing  
position. The backfeed function repositions the label stock for printing.  
The Backfeed function is enabled if DSW3-4 is in the Off position. When 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 is 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. The full adjustment range is +/- 3.75 inches from nominal. The backfeed  
adjustment procedure is as follows:  
1. Turn the printer on.  
2. Press the LINE key to place the printer in the Off-Line status.  
3. Press the FEED key to feed out a blank label while observing the dispensement position.  
4. Adjust the OFFSET potentiometer on the front control panel as deemed necessary.  
5. Repeat steps 4 and 5 until a label is fully released from the liner.  
DISPLAY  
This potentiometer is used to adjust the contrast of the LCD display for optimum viewing under  
various lighting conditions.  
PRINT  
The PRINT potentiometer is used to adjust the amount of heat (i.e., power) applied to the head  
for printing. It provides a continuous range of adjustment. Maximum print darkness is obtained by  
turning the potentiometer all the way clockwise and a maximum counterclockwise setting will give  
the lightest print.  
NOTE: Adjustment of the PRINT potentiometer will affect the darkness in all  
of the command code, speed, and darkness ranges.  
LCD PANEL PRINTER CONFIGURATION  
The LCD Panel allows the printer to communicate with the operator. The operator communicates  
with the printer largely through the use of the LINE and FEED keys. Many settings may also be  
controlled via software commands. Where software commands and control panel settings  
conflict, the printer will always use the last valid setting.  
There are seven 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.

PITCH OFFSET  
+ 00mm  
The label Pitch is the distance from the leading edge (the edge that comes out  
of the printer first) of a label and the leading edge of the next label. The  
leading edge position of the label can be adjusted relative to the print head +/-  
49 mm in increments of 1mm. Once the position is set, it can be fine adjusted  
+/- 3.75 mm using the PITCH potentometer.  
1. The cursor will initially be positioned over the Pitch Direction setting. Use  
the LINE key to step to the positive (+) or negative (-) selection. A positive  
selection moves the leading edge of the label forward (away from the print  
head) while a negative selection moves the leading edge of the label back  
into the mechanism.

PRINT OFFSET  
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 label edge out of the printer while making it  
negative moves it back into the printer. Horizontal Offset is the distance that  
the label image is shifted either to the right or left on the label. The image is  
shifted to the left (towards the inside edge of the label) for a positive setting  
and it is shifted to the right (towards the outside edge of the label) for a  
negative setting. This setting changes the base reference point for all  
subsequent label jobs. It’s 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 is 3600 for vertical  
offset and 3199 for horizontal. If the allowable limit is exceeded, the printer will  
not accept the selection.

GAP  
INPUT  
[X.XXV]  
[X.XV]  
The printer determines 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 the threshold voltage level to  
be manually set 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.

DEFINITION  
GAP  
[X.XXV] GAP - When setting the “gap” threshold, the voltage shown on the top line of  
INPUT  
[X.XV]  
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  
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). Ensure the label is fully 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 ranges:  
Backing with label = 2.0V to 3.5V  
Backing without label = Less than 1.0V  
If the measured values are outside this range, it may be difficult 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.  
3. Calculate the starting point voltage using the formula.  
4. Use the LINE and FEED keys to step the counter to the desired setting.  
The reading will advance to a setting of 4.9 (the maximum voltage). 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 and the head is closed.  
5. Once the setting is correct, pressing the ENTER key will accept the  
setting and advance the next display.

nothing but the label under the sensor and then again with the printed “eye”  
mark under the sensor. The formula for this is:  
(High Voltage Level + Low Voltage Level) x 0.5 = Start Value  
1. Insert a label into the sensor and close the label holder. Make sure the  
printed “eye” mark is not under the sensor. Record the voltage shown on  
the top line of the LCD panel. This line should have the message “EYE”  
on the top line (DIP switch DSW2-2 = ON).  
2. Pull the label forward until the “eye” mark is positioned under the sensor  
(the voltage reading should be at its highest point). Record the voltage  
shown on the top line of the LCD panel. The voltage ranges measured  
should be within the following ranges:  
Eye-Mark = 2.5V to 3.5V  
Label Only = Less than 1.0V  
If the measured values are outside this range, it may be difficult finding a value  
that will work properly under all conditions. If this is the case, a higher quality

TROUBLESHOOTING PROCEDURES  
The procedures below provide in depth instructions on symptom analysis of specific  
components. If it is suspected that the problem lies within one of these components, refer to the  
relative instructions.  
RS232 SERIAL INTERFACE  
•
Ensure the serial cable is thoroughly connected to the PC and the printer.  
CAUTION: 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 INTER-  
FACE CIRCUITRY AND IS NOT COVERED BY WARRANTY.  
•
Ensure the serial cable is not defective. The minimum requirements is that a Null Modem  
Cable or correct Pin Outs be used and that it be manufactured to specifications. Refer to the  
Interface Specifications section of this manual.  
•
•
Ensure the RS232 Interface Module is installed. Different module types will have an impact  
on transmission speed.  
Ensure the data stream is correct, all letters of command codes are in upper case, and with-  
out spaces. Carriage Returns are also not acceptable in line fields.

Section 6: Troubleshooting  
•
•
Ensure the Baud rate, Parity, Data Bits, and Stop Bits are consistent with that of computer.  
Print a Configuration Test Label to determine the RS232 settings.  
Ensure the printer is receiving from the computer using a Receive Buffer Hex Dump. Refer to  
the Hex Dump procedure in this manual for instructions. The printer will print (only once) a  
hexadecimal dump of everything it has received from the host computer. Each hexadecimal  
character represents a character the printer received. Analyze and troubleshoot the data  
stream.  
NOTE: A small label may produce a large amount of data when printed in  
Hex Dump.  
While checking the hex dump printout, look for ODH OAH (carriage return and line feed) char-  
acters 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 Basic is  
being used, it may be adding these characters automatically as the line wraps. Adding a  
width statement to your program can help suppress these extra ODH OAH characters by  
expanding the line length up to 255 characters.  
If not programming in BASIC, check to see if the equivalent statement in the language exists  
to suppress extra carriage returns and line feeds from data being sent to the printer. The data  
stream must be one complete line going to the printer.  
UNIVERSAL SERIAL BUS (USB) INTERFACE  
If nothing prints when during a test print, verify that the device drivers have been successively  
installed by performing the following:  
1. Click on Start, Settings, and then Control Panel.  
2. Click on System within the new window.  
3. Click on the Device Manager tab.  
4. Ensure that the View Device By Type is checked.  
5. Scroll down to SATO-USB Device and ensure that errors do not exist. Reinstall as required.  
6. Reboot the PC and the printer.  
7. Contact Microsoft technical support for further assistance as required.  
PARALLEL INTERFACE  
•
•
•
Ensure the printer cable is thoroughly connected to the PC and the printer.  
Ensure the printer cable is connected to the correct ports on each end.  
Ensure the printer cable (IEEE1284) meets specifications. The computer may not be able to  
communicate correctly otherwise.  
•
Ensure the Interface Module is installed.

Section 6: Troubleshooting  
•
•
•
Ensure the data stream is correct, all letters of command codes are in upper case, and with-  
out spaces.  
Ensure protocol codes are set for standard or non-standard and that they are consistent with  
the data stream.  
Ensure the printer is receiving from the computer using a Receive Buffer Hex Dump. Refer to  
that procedure for instructions. The printer will print (only once) a hexadecimal dump of  
everything it has received from the host computer. Each hexadecimal character represents a  
character the printer received. Analyze and troubleshoot the data stream.  
NOTE: A small label may produce a large amount of data when printed in  
Hex Dump.

If not programming in BASIC, check to see if the equivalent statement in language exists to  
suppress extra carriage returns and line feeds from data being sent to the printer. The data  
stream must be one complete line going to the printer.  
LAN ETHERNET INTERFACE  
•
If the printer does not come up ready: Ensure the printer is powered on, all cables are con-  
nected, and the printer is on-line. If possible, connect a terminal to the serial port and observe  
for a boot prompt indicating the print server firmware has not been loaded properly. If reload-  
ing does not correct the problem, try pressing switch 1 for more than 10 seconds. If the prob-  
lem persists, the product may be defective.  
•
If the printer comes up ready but will not print: There is a problem with the interface  
between the server and the printer, network connection or cabling, or a queue setup flaw. The  
queue setup flaw could be the result of a faulty print server setup or other protocol-related  
scenarios. Systematically perform checks and tests to isolate the cause.  
The interface between the printer and server may be checked by waiting approximately two  
minutes after the printer is powered on and then run a self-test label. If a self-test label does  
not print, there could be a hardware problem. Double check the cable connections. In some  
rare cases, disabling NBUF with the command SET PORT P1 NBUF DISABLED will solve  
the problem.  
If connecting to a 10baseT network, verify that the OK LED is illuminated. If the appropriate  
LED’s are not on, there is a possibility of a defective cable or connector. Try connecting a  
different cable, port, or device to observe the results.  
If using a repeater or hub, ensure that SQE is turned off at the hub (this is the default setting  
for most hubs). Also, test the hub or repeater by trying the print server on a different port.

Section 6: Troubleshooting  
If using a bridge or router located between the print server and the host computer, ensure  
that the device is setup to allow the print server to send and receive data from the host. For  
example, a bridge can only be set up allow certain types of Ethernet addresses to pass  
through (a process known as filtering). Such a bridge must be configured to allow print server  
addresses. Likewise, a router can be set up to only pass certain protocols. Ensure that the  
desired protocol can be passed through to the print server. In the case of routers, also ensure  
that the protocol is routable (LAT, NetBEUI, and DLC/LLC are not routable.  
Ensure that you are not attempting to perform an illegal operation such as printing a label l  
larger than the printer can handle.  
Check the protocol troubleshooting sections provided with the Ethernet Interface Module for  
additional causes of intermittent printer problems.  
•
Experiencing intermittent printing problems: Excessive NetWare polling may be a big cause  
of intermittent problems. Ensure that only the needed NetWare file servers have been  
enabled (do a SHOW NETWARE command from the print server console to see the enabled  
file servers). If V3.21 or earlier versions of firmware is in use, ensure that NetWare polling is  
disabled by using the console command SET NETWARE RANGE 0. If Netware is not in use,  
disable NEtWare entirely with the command SET NETWARE DISABLED.  
Check the individual troubleshooting sections provided with the Ethernet Plug-In Interface  
Module for additional causes of intermittent printer problems.  
TP TEST MODULE USAGE  
The SATO TP Test Module is a purchase option specially designed and sold by SATO America  
to assist in troubleshooting SATO Printers. The use of this device will facilitate the identification  
and isolation of problem circuitry and for voltage adjustment.

TIMING BELT REPLACEMENT  
The M84pro Printer utilizes four timing belts coupled with dual action toothed pulleys to provide  
drive distribution throughout the assembly. Two belts are configured to transfer torque from the  
motor to the label feed roller. A third belt transfers torque from the feed roller to the platen roller.  
And the fourth transfers torque from the platen roller to the ribbon rewind spindle. All four  
operating in conjunction provide the total drive configuration for the primary machine.  
The optional cutter assembly has its own drive mechanism that operates when directed by the  
printer, but independently of the printer drive assembly. The cutter drive assembly also  
comprises drive belts and pulleys. Those will not be addressed in this procedure.

FEED ROLLER ADJUSTMENT  
Feed roller adjustment is used for fine tuning label tracking. By adjusting the pressure between  
the upper and lower rollers, the media may be directed through the printer as desired. If mal-  
adjusted, the label media will have a tendency to want to track to the left or to right depending on  
which side has the greatest pressure.  
A properly adjusted upper and lower feed roller assembly will have evenly applied pressure to  
each side and be properly aligned. The pressure difference between each side should be 100  
grams or less. A tension gauge will be required to measure the tension.  
To acquire the desired adjustment; the upper, the lower, or both feed rollers may require  
manipulation. Each roller may be adjusted along opposing X and Y axis. Different variations may  
be required until the correct adjustment is achieved.
