Communications Diagnostic Self-test

The Communications Diagnostic Mode is a troubleshooting tool for checking the interconnection between the printer and the host com- puter.When “Diagnostics” is selected, all data sent to the printer will be printed as straight ASCII hex characters. The printer prints all received characters including control codes like CR (Carriage Return).

To enter the Communications Diagnostics mode, open the front panel door and press and hold the + key while turning the printer power ON. Release the key anytime after the first front panel LED turns OFF.

Send a label format from the host computer to the printer and observe the printout on the label stock. Figure 23 provides an example of the Diagnostic Mode printout.

NOTES:An FE indicates a framing error.

An OE indicates an overrun error.

An PE indicates a parity error.

If errors are indicated, check that your communication parameters are correct.
