Section 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. M-8485Se printers utilize a Plug-In Interface Module for maximum printer configuration flexibility. The following information is presented in this section.
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.
Section 3. Interface Specifications 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.
Section 3. Interface Specifications The Receive Buffer 0 1MB 2.95MB DTR High or X-On DTR Low or X-Off Buffer Available 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.
Section 3.
Section 3. Interface Specifications 3.5 RS232C Serial Interface The High Speed Serial Interface is a Plug-In Interface Module that can be installed in the printer by the user.
Section 3.
Section 3. Interface Specifications RS232C Interface Signals PIN DIRECTION 1 Reference 2 To Host 3 To Printer SIGNAL DESCRIPTION FG (Frame Ground) TD (Transmit Data) - Data from the printer to the host computer. Sends X-On/X-Off characters or status data (Bi-Directional protocol). RD (Receive Data) - Data to the printer from the host computer. To Host RTS (Request to Send) - Used with Ready/Busy flow control to indicate an error condition.
Section 3. Interface Specifications X-On/X-Off Flow Control X-On/X-Off flow control must be used whenever hardware (Ready/Busy) flow control is not available or desirable. Instead of a voltage going high/low at pin 20, control characters representing "Printer Ready" (X-On = 11 hexadecimal) or "Printer Busy" (XOff = 13 hexadecimal) are transmitted by the printer on pin 2 (Transmit Data) to the host. In order for this method of flow control to function correctly, the host must be capable of supporting it.
Section 3. Interface Specifications 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.
Section 3. Interface Specifications ID - This is a two byte number identifying the current print job ID. The print job ID is defined using the 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).
Section 3.
Section 3. Interface Specifications 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.
Section 3.
Section 3. Interface Specifications Status Response (Cont) Counter Status (SOH + ME) Upon receipt of an SOH (hexadecimal 01) followed immediately by an ASCII ME (hexadecimal 4D45) causes the printer to return a 28 byte Head Counter Status Word bounded by an STX-ETX pair that reports the current status of the printer life counters.
Section 3. Interface Specifications Status Response (Cont) System Version Information Upon receipt of an SOH (hexadecimal 01) followed immediately by an ASCII SB causes the printer to return a 50 byte Printer Status Word bounded by an STX-ETX pair that reports the system version of the printer.
Section 3. Interface Specifications Status Response (Cont) Font Configuration (SOH + FG) Upon receipt of an SOH (hexadecimal 01) followed immediately by an FG (hexadecimal 4647) causes the printer to return a 102 byte Font/Graphics Status Word bounded by an STX-ETX pair that reports information on the stored font or graphic. Note: The printer must be in the Font/Graphic Download mode before a response will be received.
Section 3. Interface Specifications Interface Status Upon receipt of an SOH (hexadecimal 01) followed immediately by an ASCII IG causes the printer to return a 1 byte Interface Status Word bounded by an STX-ETX pair that reports the type of interface connection currently set in the printer.
Section 3. Interface Specifications 3.9 Accessory (EXT) Connector The EXT connector on the rear panel of the M-8485Se printer is intended for use with the external printer accessories such as label rewinders or applicators. The 14 pin Centronics type connector provides a choice of four different output signals along with various error conditions. A DB-9 to 14 pin Centronics adapter cable is provided for legacy applications.
Section 3. Interface Specifications 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.

Section Troubleshooting 8 8.1 Overview This section has been devised to help you if you are unable to produce output on the M-8485Se printer. Use this section to make sure the basics have been checked before deciding you are unable to proceed further. This section covers the following: To help you, this section has been divided into the following parts.
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.
Section 8. Troubleshooting The IEEE1284 Parallel Interface (Cont) c. Verify the following: You have not typed a "0" (zero) for an "O" (letter) or vice-versa. You have not missed any 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.
Section 8. Troubleshooting 8.4 The RS232C (Serial) Interface 1. Is the RS232C Serial cable connected securely to your serial port on the PC (DB-25S Male) and to the RS232C connector on the printer? Warning: Never connect or disconnect interface cables (or use a switch box) with power applied to either the printer or the host. This may cause damage to the interface circuitry and is not covered by warranty. 2.
Section 8. Troubleshooting 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.
Section 8. Troubleshooting 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.
Section 8. Troubleshooting The LAN Ethernet Interface (Cont) 5. Also verify that the host computer and the print server are either on the same subnet (for example, if the print server has a subnet mask of 255.255.255.0, the host must have the same subnet mask) or that the router is properly configured to pass data between the two devices. 6. Make sure that the /etc/printcap file (if applicable) is typed in correctly.
Section 8. Troubleshooting The LAN Ethernet Interface (Cont) 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.
Section 8. Troubleshooting The LAN Ethernet Interface (Cont) Windows NT/LAN Server Troubleshooting If you are having trouble printing with Windows NT or LAN Server, check the following: 1. Make sure you can print from the print server using DOS or OS/2 comand PRINT ipaddress, where ipaddress is the IP address of the print server. If you cannot print from the print server you will not be able to print. 2.
Section 8. Troubleshooting 8.7 Error Signals The LCD display, Front Panel LED Indicators and Buzzer provide a visual/audio indication of the type of error encountered.
