RFID Symptoms

External reader cannot confirm RFID tags are programmed.

■Is the printer set up correctly? Print a configuration label to verify RFID
version. See “Auto Calibration” on page 14.
■Check if supported RFID media is loaded correctly.

VOID messages are printed across media.

■Verify tag type is properly selected in ZPL II. Use RFID media with
supported tag type. Edit ZPL II to select proper tag type or increase
retries.
■ZPL II is attempting to write to a non-existent block. Some tags’ blocks
are identified as 0-7. If ZPL II attempts to write to block “8,” it will fail.
■Check voided tag on external reader. If this is a media probelm, discard
or return bad tags.
■Media's transponder is out of range from printer's antenna. Contact
Zebra for the latest media and transponder specifications.

Nothing is printed.

■See if the correct media is loaded or load new, fresh media.
■See if tags can be read/programmed using other hardware.
■Verify ZPL II RFID commands. Debug the printing program.
■Tag is out of reach of the antenna or too close. Verify tag alignment.
■Wrong type of tag was selected. Check ZPL II.
■Block is write protected. Ensure that the tag is not write protected.
■Aluminum and other metals within tag may interfere with read/write.
Make sure media meets requirements.
■Increase the number of retries in the ZPL II commands.
■Time out may have occurred during internal communication. Cycle
power and try printing label again.
Call a service technician if you have been unsuccessful in getting your
expected print out and data.
