Troubleshooting

Communication Issues

This section identifies problems with communications, the possible causes, and the

recommended solutions.

Issue: Label Job Sent, No Data Transfer

A label format was sent to the printer but was not recognized. The DATA light does not flash.

Possible Cause

The communication parameters are incorrect.

Resolution - 1

Check the printer driver or software communications settings (if applicable).

Resolution - 2

Serial Port Only - Check the printer’s handshake protocol and serial port settings. The

setting used must match the one being used by the host computer. See Serial Interface for

the printer’s default serial port settings.

Resolution - 3

The serial cable you are trying to use may not be a standard DTE or DCE type cable, is

damaged, or is too long per the RS-232 Serial ports specifications. See Serial Port

Interface.

Issue: Label Job Sent, Skips Labels or Prints Bad Content

A label format was sent to the printer. Several labels print, then the printer skips, misplaces, misses,

or distorts the image on the label.

Possible Cause

The serial communication settings are incorrect.

Resolution - 1

Check the printer driver or software communications settings (if applicable). Ensure that

the flow control settings and other serial port handshake setting match the host system.
