Communication Diagnostics Test
The communication diagnostics test is a troubleshooting tool for checking the interconnection
between the printer and the host computer. When the printer is in diagnostics mode, it prints all
data received from the host computer as straight ASCII characters with the hex values below
the ASCII text. The printer prints all characters received, including control codes such as CR
(carriage return). Figure 20 shows a typical test label from this test.
Figure 20 • Sample Communications Diagnostics Test Label
To use communications diagnostics mode, complete these steps:
1. Set the print width equal to or less than the label width being used for the test. (See PRINT
WIDTH on page 110.)
2. Set the DIAGNOSTIC MODE option to ENABLED. (See DIAGNOSTIC MODE
on page 128 for more information.)
The printer enters diagnostics mode and prints any data received from the host computer
on a test label
3. Check the test label for error codes. For any errors, check that your communication
parameters are correct.
Errors show on the test label as follows:
• FE indicates a framing error.
•
OE indicates an overrun error.
•
PE indicates a parity error.
• NE indicates noise.
4. To exit this self test and return to normal operation, power cycle the printer or set the
DIAGNOSTIC MODE option to DISABLED.
Note • The test label prints upside-down.
