RFID Issues
Printer Stops at RFID Inlay
Issue Possible Cause Recommended Solution
The printer stops at the
RFID inlay.
The printer calibrated the label
length only to the RFID inlay
instead of to the interlabel gap.
1. Tap the Advanced icon and then select FEED
for the Power Up and Head Close actions.
2. Manually calibrate the printer (see Calibrate
the Ribbon and Media Sensors on page 92).
Voided Labels
Issue Possible Cause Recommended Solution
Low yields. Too many
RFID tags per roll are
voided.
The RFID labels are not within
specifications for the printer,
which means that the
transponder is not in an area
that can be programmed
consistently.
Make sure that the labels meet transponder
placement specifications for your printer. See
http://www.zebra.com/transponders for
transponder placement information.
For more information, refer to the RFID
Programming Guide 3, or contact an authorized
Zebra RFID reseller.
Incorrect read and write power
levels.
Change the RFID read and write power levels.
For instructions, refer to the RFID Programming
Guide 3.
Radio frequency (RF)
interference from another RF
source.
Do one or more of the following as necessary:
• Move the printer away from fixed RFID
readers.
• Make sure that the media door is closed at all
times during RFID programming.
The printer is using outdated
printer firmware and reader
firmware versions.
Go to http://www.zebra.com/firmware for
updated firmware.
