The RFID-enabled
print engine voids
every label.
(Continued from previous page.)
You are using an incorrect
programming position,
particularly if the tags being
used are within print engine
specifications.
Do one or more of the following as necessary:
• Check the RFID programming position , or
the program position setting in your label
designer software. If the position is incorrect,
change the setting.
• Restore the RFID programming position back
to the default value.
Refer to the RFID Programming Guide for more
information.
You are sending RFID ZPL or
SGD commands that are
incorrect.
Check your label formats. Refer to the RFID
Programming Guide for more information.
Low yields. Too many
RFID tags per roll
are voided.
The RFID labels are not within
specifications for the
print engine, 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 print engine.
See http://www.zebra.com/transponders for
transponder placement information.
Refer to the RFID Programming Guide or
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/transponders 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.
Refer to the RFID Programming Guide or
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.
Refer to the RFID Programming Guide for
instructions.
Radio frequency (RF)
interference from another RF
source.
Do one or more of the following as necessary:
• Move the print engine away from fixed RFID
readers.
• Make sure that the media door is closed at all
times during RFID programming.
The print engine is using
outdated print engine firmware
and reader firmware versions.
Go to http://www.zebra.com/firmware for
updated firmware.
