GENERAL DESCRIPTION
The M84Pro printer was designed for continuous industrial and commercial applications as self­evident 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.
S
INGLE JOB BUFFER
The printer receives and prints one job at a time. Each job must not exceed 2.95 MB.
M84Pro Service Manual PN: 9001113A Page 3-1
Page 15
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.

RS232C SERIAL INTERFACE SIGNALS
PIN DIRECTION SIGNAL DEFINITION
1 Reference FG (Frame Ground) 2 To Host TD (Transmit Data) - Data from the printer to the host computer. Sends X-On/
X-Off characters or status data (bi-directional protocols). 3 To Printer RD (Receive Data) - Data to the printer from the host computer. 4 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., ribbon out, label out). 5 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. This line must be high before data is transmitted. If this line is not
being used, it should be tied high (to pin 20). 7 Reference SG (Signal Ground)

RS232C SERIAL INTERFACE SIGNALS
PIN DIRECTION SIGNAL DEFINITION
20 To Host DTR (Data Terminally 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.

* 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-O
N/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 X­On, 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.

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
M84Pro Service Manual PN 9001113A Page 3-6
Page 20
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.
E
NQUIRE (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 Six bytes defining the number of labels remaining in the current
print job. The range is from 000000 to 999999 labels.
Job Name
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.
P
RINT 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.
M84Pro Service Manual PN: 9001113A Page 3-7
Page 21
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.
P
RINT 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.

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 DSW3­1 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.

This potentiometer is used to adjust the contrast of the LCD display for optimum viewing under various lighting conditions.
P
RINT
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.

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.

2. Press the FEED key to select the option and advance to the Print Offset
display.
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.

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.

LCD DISPLAY DEFINITION
GAP [X.XXV] INPUT [X.XV]
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
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.

EYE - When setting the “eye” threshold, the voltage must be measured with 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 label may be needed to get adequate performance.

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 with­out spaces. Carriage Returns are also not acceptable in line fields.
M84Pro Service Manual PN 9001111A Page 6-4
Page 63
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 OD
H 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 OD
H 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.
U
NIVERSAL 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.
ARALLEL INTERFACE
P
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.

LAN E
THERNET INTERFACE
If the printer does not come up ready: Ensure the printer is powered on, all cables are con­nected, 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 reload­ing does not correct the problem, try pressing switch 1 for more than 10 seconds. If the prob­lem 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.
M84Pro Service Manual PN 9001111A Page 6-6
Page 65
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.

NOTE: Figures 10-2 and 10-3 of the Diagrams & Schematics section provides guidance on media and ribbon installation.
4 Begin continuous printing of self-test labels.
NOTE: The self-test label identifies if any elements are malfunctional. To the far right of the Head Check row, OK will be printed if elements are not missing and NG if any are missing. Begin a troubleshooting process should difficulties be found. It is recommended that the troubleshooting process begin at the rear of the printer and work forward.
5 Adjust left or right screw/s (5) to manipulate print head (1) as deemed necessary until the
print image is deemed acceptable.
NOTE: The print speed and darkness should be set so as to assist in determining if the print image is being improved during alignment. The speed and darkness settings are identified on the self-test label. Adjust as deemed necessary.
NOTE: The self-test label provides a scale in the lower right and left corners to assist in adjustment. The label is properly aligned perpendicular to the print head when the scale increments are proportionate on each side.
6 Retighten two set screws (3) and thumbscrew (2) to complete the adjustment process.
PRINT HEAD BALANCE ADJUSTMENT
Print quality may be further optimized by the adjustment of the print head balance. When the print head is balanced, there is equal pressure applied across the print media and platen roller by the print head. The left side of the print head remains fixed and the right side is adjusted vertically to obtain balance. To adjust print head balance, follow the instructions below.
1 Visually inspect the condition of the feed and platen rollers and replace as necessary.
2 Adjust the feed roller in accordance with its relative procedure in this manual.
3 Load printer with media and ribbon as applicable.
