4.3 INTERFACE TROUBLESHOOTING (Cont'd)
PARALLEL 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 a IEEE1284 printer cable is being used.
Ensure the host's peripheral settings are set to ECP 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
0Dhex and/or 0Ahex (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.
Try another port to isolate the problem.
Replace the main circuit board if determined to be the problem.
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.

4.4 TEST PRINT TROUBLESHOOTING

This chapter provides instruction on special printing to identify and resolve specific print problems.
4.4.1 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 are provided in the ASC ll format. Refer to Section 3.9 HEX Dump Mode for more details to perform this
activity.
4.4.2 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 3.3 User Test Print Mode for
more details to perform this activity.
