|---|---|
Settings are lost or ignored. | Some parameters are set incorrectly. Printer settings may have been changed but not saved (ex., the ^JU ZPL command was not used to save the configuration before turning printer power OFF.) Cycle printer power OFF and then back ON to verify settings have been saved. |
The label format/form commands or commands sent directly to the printer have syntax errors or have been used incorrectly.
See the ZPL programmer’s guide to verify and use the correct command usage and syntax. | |
The prefix and delimiter characters set in the printer do not match the ones in the label format. Verify that the ZPL programming settings of the Control, Command, and Delimiter settings are correct for your system software environment. Print a Configuration Report or use display’s Language Menu (if present) for these three menu items and compare it the commands in the label format/form you are trying to print. See Testing Printing with the Configuration Report and ZPL Configuration. | |
The MLB (Main Logic Board) may be malfunctioning. Firmware is corrupted, or the MLB needs service.

Non-continuous labels are treated as continuous labels. A non-continuous label format with matching media loaded in the printer, was sent to the printer, but it prints like it is continuous media. | The printer was not calibrated for the media being used, or the printer is configured for continuous media. Set the printer for the correct media type (gap/notch, continuous, or mark) and calibrate the printer using Running a SmartCal Media Calibration, if necessary use Manually Calibrating Media for hard-to-calibrate media types. |

Battery is too hot or too cold. Remove the battery from the printer and check charge status by charging the battery. Let the battery cool down or warm up to ambient temperature, then recheck the battery charge. If the problem is not with the battery charge status or temperature, replace the battery. |
