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 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 22 shows a

typical test label from this test.

Figure 22 • 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 66 for more information.

2. Set the printer to DIAGNOSTICS. For instructions, see Set Communications Mode

on page 77.

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.
