RFID Symptoms
RFID tags generally not 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.
■ Verify voided tag on external reader. Discard bad tags if this is a media
problem.
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.
