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.

Adjusting the Label Sensor

The M-8485Se printers can position labels using either a label gap (transmissive) or an "Eye-

Mark" (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.

2.1 Dip Switch Settings

Two DIP switches (DSW2 & DSW3) are located inside the cover. These switches can be used to set:

• Thermal transfer or direct thermal mode

• Head Check Mode

• Hex Dump Mode

• Label sensor enable/disable

• Single Job or Multi-Job Receive Buffer

• Operation Mode

DIP SWITCHES

In addition, a third DIP switch (DSW1) is located on the RS232 Serial Adapter card and is used to set the RS232C transmit/receive parameters.

DSW1

PN 9001080

Rev. A

Each switch is an eight section toggle switch. The On position is always to the top. To set the switches, first power the unit Off, then position the DIP switches.

Finally after placing the switches in the desired positions, power the printer back on. The switch settings are read by the printer electronics during the power-up sequence. They will not become effective until the power is cycled.

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 PROCEDURE

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 PROCEDURE

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.

Service Manual


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.

Print Offset

print offset 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.

Gap [X.XV]

Input [X.XV}

gap [x.xv] input [x.xv]

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.

LCD Panel Printer — Service Mode

Gap [X.XV]

Input [X.XV}

gap [x.xv] 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

STEP

1.

2.

3.

4.

5.

PROCEDURE

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.

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.

Calculate the starting point voltage using the formula.

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.

Once the setting is correct, pressing the FEED key will accept the setting and advance to the Online Feed display.

Now pull the label forward until the "eye" mark is positioned under the sensor

(the voltage reading shon on the top line of LCD panel. The voltage ranges measured should be within the following ranges:

Label Only = 0.3 - 0.5V

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 4.4.

Calculate the starting point voltage using the formula.

Interface Specifications

3.1 Overview

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.

Section

!

M-8485Se printers utilize a Plug-In Interface Module for maximum printer configuration flexibility.

The following information is presented in this section.

Interface Types

The Receive Buffer

IEEE1284 Parallel Interface (Standard with unit)

Optional RS232C Serial Interface

General Specifications

Electrical Specifications

Pin Assignments

Ready/Busy Flow Control

X-On/X-Off Flow Control

Optional Universal Serial BUS (USB)

Optional Local Area Network (LAN)

BI-Directional Communications

Ext Connector

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.


Service Manual

Page 3-1

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 X-

On 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"

0

2.0 MB 2.95MB

*DTR High or

X-On

Buffer Near Full

DTR Low or

X-Off

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

( DTR "low" or X-Off ) until the problem is corrected and the printer is placed online. The 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.

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


Service Manual

PN 9001080

Rev. A


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" ( 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 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.

<ESC>A .. Job#1 .. <ESC>Z<ESC>A .. Job#n .. <ESC>Z

Example: <ESC>A .. Job#1 .. <ESC>Z

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.

3.7 Local Area Network (LAN) Optional Interface

A Local Area Network (LAN) 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. The driver must be loaded on your PC and the PC must be configured to run one of the supported network protocols using a 10/100BaseT LAN connection. Details for loading the LAN driver are contained in the LAN Interface Manual that is shipped with each printer with a LAN Optional interface installed.

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 Multi-

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>

Page 3-10


Service Manual

PN 9001080

Rev. A


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.

PN 9001080

Rev. A

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.

Status Response

The second method of determining printer status is to integrate the printer with specific commands. The response from these commands will provide specific information about the printer status depending upon the command. This allows the controlling application to determine the status of a printer when it is located in a remote location.

Print Status (SOH + MG)

Upon receipt of an SOH (hexadecimal 01) followed immediately by an ASCII MG causes the printer to return a 30 byte Printer Status Word bounded by an STX-ETX pair that reports the current operating status of the printer.

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.

Electrical Checks and Adjustments

Section

"

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.

To adjust the Ribbon Unwind Clutch, perform the following steps:

PROCEDURE

Remove the ribbon if installed.

Place an empty ribbon core on the ribbon unwind spindle. Attach the free end of the string to the tension gauge. Fig. 5-1, 5-2

Wind the string tightly around the ribbon core in a single layer and in a clockwise direction. Attach the free end of the string to the tension gauge.

Gradually lift the tension gauge, pulling the string to unwind it from the core.

Once the spindle begins to move, the gauge should indicate 600 to 800 grams of tension. Excessive or insufficient tension must be corrected by adjusting the ribbon unwind clutch.

To adjust the clutch, loosen the set screw and move the adjust nut CW for more tension and CCW for less tension. Tighten the set screw and repeat

Steps 3 and 4 until the correct tension is achieved.

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>AData<ESC>Z b. Verify that you've included all required parameters in the data stream.

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 0D

H

0A

H

(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 0D

255 characters.

characters by expanding the line length up to

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.

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

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.

The LAN Ethernet Interface (Cont)

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.

Page 8-6


Service Manual

Rev. A



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).

Rev. A


Service Manual

Page 8-7



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).

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.

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).
