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/id/zebra/na/en/index/
products/supplies/rfid_supplies/
rfid_transponder_inlay.html for transponder
placement information.
Contact an authorized Zebra RFID reseller for
more information.
Some RFID tags are more
sensitive than others and may
require special printer settings.
1. Verify that the printer is set for the correct
write power. See
http://www.zebra.com/id/zebra/na/en/index/
products/supplies/rfid_supplies/
rfid_transponder_inlay.html for the
recommended power setting for each tag
type.
2. If necessary, run the ^HR command to
manually calibrate the transponder position.
3. If the problem persists, consider using a
different tag type.
Contact an authorized Zebra RFID reseller for
more information.
Incorrect read and write power
levels for the RFID tag type.
Change the RFID read and write power levels
(see View or Change RFID Read Power
on page 24 or View or Change RFID Write
Power on page 25).
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The printer is using outdated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.
With a Gen 2 tag, no
data is written to the
tag even though the
printer says that the
write operation
succeeded.
The RFID reader/encoder is not
enabled for Gen 2.
Check Table 9, Supported Tag Types and Default
Va lues , on page 111 to see if your printer
supports Gen 2 tags.
• If your printer supports Gen 2 tags, make sure
that you are using the appropriate firmware
version. Download printer and reader
firmware, if necessary.
• If your printer does not support Gen 2 tags,
you will not be able to use these tags with your
printer.
