LAN ETHERNET INTERFACE
CHK TROUBLESHOOTING STEP
Ensure the interface has been correctly configured. Wait two minutes and run self-test to verify. If a
test label does not print, there may be a hardware problem.
Ensure the serial cable meets specifications and is correctly connected at each end.
Ensure the cable and its ports are not defective.
Ensure that a faulty print server or other protocol related scenarios are not creating a queue setup
issue. Systematically perform checks and tests to isolate the cause.
If using TCP/IP, ensure a valid IP address is specified and that all parameters are correct (subnet
mask, gateway, etc.). Attempt to PING the IP address assigned to the network interface.
Install the IPX/SPX protocol on a workstation to determine if the network device can be discovered
via the MAC address. If able, configure the appropriate protocols and retest connectivity.
Use a crossover cable to isolate the printer from the network by connecting from the interface and
workstation. Verify that the parameters match on each. Test connectivity.
WIRELESS LAN INTERFACE
CHK TROUBLESHOOTING STEP
Ensure the interface has been correctly configured. Wait two minutes and run self-test to verify. If a
test label does not print, there may be a hardware problem.
Check the Wireless LAN connection by using the Ping command. If the Ping fails, double-check all
WLAN hardware and connection settings. Print test labels to verify that the new settings can work.
If the Ping test is OK, check the printer’s location to adequate signal strength. For weak signals, try
relocating the printer close to the access point. If the signal strength is high, replace the WLAN
interface card.
UNIVERSAL SERIAL BUS (USB) INTERFACE
If nothing prints during a test print, verify the device drivers have been successively
installed by performing the following:
Click on Start, Settings, and then Control Panel.
Click on System within the new window.
Click on the Device Manager tab.
Ensure that the View Device By Type is checked.
Scroll to printer driver for your SATO device. Ensure that errors do not exist. Reinstall the driver as
required.
Reboot the PC and the printer.
Contact Microsoft technical support for further assistance as required.
