Possible Cause(s) and Remedies
Settings are lost or ignored.
Some parameters are set incorrectly. Printer settings may have been changed but not saved (for example, the ZPL
^JUcommand 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 or form commands or commands sent directly to the printer have syntax errors or have been used incorrectly.
See the ZPL Programming Guide to verify and use the correct command usage and syntax. Links to the location of the guide are in About this Guide.
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 the Language Menu on the printer display (if present) for these three menu items and compare them to the commands in the label format or form you are trying to print. See Test Printing with the Configuration Report, Language Menu and ZPL Configuration.
The Main Logic Board (MLB) may be malfunctioning. Firmware is corrupted, or the MLB needs service.
If the printer does not recover from this error, call a service technician. The MLB is NOT a user serviceable item.
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.
For ZD620 printers with the display, see MEDIA TYPE in the Settings menu to check and set the media type for the media you are using. See Settings Menu.
The printer locks up.
All indicator lights are on and the printer locks up or the printer locks up while restarting.
Printer memory may be corrupted.
