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 ,

BASIC, refer to the beginning of the Command Code section in the Operator and Technical
Reference Manual.
8.5 The Universal Serial BUS (USB)
If nothing prints when doing a test print you will need to verify that the device drivers have been
successfully installed by doing the following:
1. Click on Start, then Settings and then Control Panel.
2. Within the new Window, you should have an Icon listed as System. Double click on this.
3. Click on the Device Manager tab.
4. Make sure that the View Device by type is checked. Scroll down until you get to
SATO-USB device.
5. Verify that it does not have any errors next to it. If it shows an error, remove the device and then
reinstall it.
6. Reboot the PC and the Printer.
7. Consult the Windows 98 Troubleshooting guide or contact technical support for further assistance.
