Test Print Troubleshooting - SATO DR308e Operator's Manual

Section 5: Troubleshooting
LAN ETHERNET INTERFACE
CHK
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 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.
CENTRONICS INTERFACE
CHK
Ensure the interface module is correctly installed. Run self-test to verify.
Ensure the printer cable is connected to the appropriate LPT port on the host computer. If using a Windows
printer driver, ensure the correct port is selected.
Ensure the host's peripheral settings are set for Centronics output for faster throughput. Refer to the computer
manufacturer's documentation for details.
Ensure the printer is receiving information from the computer using the Receive Buffer Hex Dump mode. Refer
to that procedure within this manual for instructions. The command stream should be continuous and possess
0D Hex and/or 0A Hex (carriage return and line feed) characters throughout. However, there should not be
either located between the start (<ESC>A and the stop (<ESC>Z) commands.
Replace the main circuit board with another to isolate the problem.

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, same data is
provided in the ASC ll format. Refer to Section 3.9 HEX Dump Mode on page 3-23 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 3.10 Test Print Mode on page 3-
24 for more details to perform this activity.
