0036 NO TAG
NO TAG FOUND Note • This error message varies by reader type.
No RFID tag was detected in the RF field. Several things can
cause this error:
• No acceptable RFID tag is in the RF field. This can happen if an
RFID label is present but the transponder is not placed correctly
within the label or if the wrong tag type is used.
• The read/write power being used is too low.
• The RFID tag is weak or dead.
Retry with another RFID tag. Make sure you have the right tag
type selected and that you are using a tag that is supported by your
printer. If the problem persists, contact Technical Support.
0037 DATA CRC An integrity check of the reader firmware failed. If the problem
persists, contact Technical Support.
0038 TAG NOT FOUND Good tag data is available, but the tag specifically requested was
not found (^RT, ^WT commands).
Repeat the process with another RFID label. If the problem
persists, contact Technical Support.
0039 LOCKED BLOCK Attempt to write to a read-only tag or to a locked block. Make sure
you have the right tag type selected and that you are using a tag
that is supported by your printer. Ensure that the block that you are
trying to write to is not already locked.
003A LOST LOCK UHF synthesizer error. Internal problem with the reader. If the
problem persists, contact Technical Support.
003B VERIFY FAILED The write operation could not be verified because the tag data
could not be read.
Check that the tag is good, and repeat the process with another
RFID label. If the problem persists, contact Technical Support.
0041 TAG DATA LOST In serial polled or RF continuous mode, incoming new tag data
overwrote old tag data between polls.
Internal problem with the reader. If the problem persists, contact
Technical Support.
0042 MEMORY ERR Non-volatile memory data element does not exist or was not found
when requesting a read of a specific element in non-volatile
memory. If the problem persists, contact Technical Support.
0043 NVM FULL Internal problem with the reader. If you are upgrading reader
firmware, try resending the file. If the problem persists, contact
Technical Support.
0044 NO NVM PRESENT Internal problem with the reader. If the problem persists, contact
Technical Support.
