5.4 TEST PRINT TROUBLESHOOTING
Chapter provides instruction on special printing to identify and resolve specific print problems.
5.4.1 Hex Dump
Allows the operator to determine if there were problems in the downloading of data. The contents of the print
buffer can be examined using the Hex Dump Mode. In the left column, each line of data received is
numbered. The center column provides the data in hexadecimal format. And in the right column, the same
data is provided in the ASC ll format. Refer to
Section 4.10 HEX Dump Mode
for more details to perform this
activity.
5.4.2 Test label printing
Allows the operator to identify specific problems regarding mechanical performance and setup. The test label
is designed to assist in the identification of print problems. Refer to
Section 4.12 Test Print Mode
for more
details to perform this activity.
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 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 that 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.
If using a repeater or hub, ensure the SQE is turned off. Also ensure the repeater port is not defective by trying
the print server on another port.
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 antenna is properly and completely installed.
Ensure the wireless LAN unit is properly installed.
Ensure the green connection lights on the back of the interface board are illuminated.
If not obtaining an IP address, check the SSID or encryption and ensure those were properly entered.
