Miscellaneous Issues
This section identifies miscellaneous issues with the printer, the possible causes, and the recommended
solutions.
Issue: Settings are Lost or Ignored
Some parameters are set incorrectly.
Possible Cause - 1
Printer settings were changed without saving them.
Resolution
The ZPL
^JU command was not used to save your configuration before turning the printer off. Cycle the
printer OFF and then back ON to verify settings have been saved.
Possible Cause - 2
The label format/form commands or commands sent directly to the printer have syntax errors or have been
used incorrectly.
• A firmware command turned off the ability to change the parameter.
• A firmware command changed the parameter back to default setting.
Resolution
Refer to the ZPL programmer’s guide to verify command usage and syntax. Go to About on page 11 for
support links to view the ZPL Programming Guide for your printer model.
Possible Cause - 3
The prefix and delimiter characters set in the printer do not match the ones in the label format.
Resolution
Verify 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 display Language Menu (if present)
for these three (3) menu items and compare it the commands in label format/form you are trying to print.
Go to Test Printing with the Configuration Report on page 178, System > Language on page 76, and ZPL
Configuration on page 339.
Possible Cause - 4
The Main Logic board may not be working properly. Firmware is corrupted or the printer needs service.
Resolution
1. Reset the printer to factory defaults. Go to System > Settings > Restore Defaults on page 86 or use the
Zebra Setup Utility and Open Printer Tools > Action > Load printer defaults.
2. Reload printer firmware. Go to Updating Printer Firmware on page 273.
3. If the printer does not recover from this error, call a service technician. This is not a user serviceable
item.
