Communications 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 (hex dump) 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 27
shows a typical test label from this test.
Figure 27 • 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 Set
Print Width on page 75 for more information.
2. Set Hex Dump mode to YES. For instructions, see Hex Dump on page 81.
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. Turn the printer off (O) and then back on (I) to exit this self test and return to normal
operation.
Note • The test label prints upside-down.
