2.4 SPECIFICATION OF RFID TAG (for B-EX700-RFID-H1-QM-R)
10) Strip Issue
Stripping performance in strip issue mode depends on the type of glue, tag, and backing paper. For
some RFID supplies used, an issue may not be performed properly in strip issue mode.
11) Caution for Minimum Label Pitch Length
When media, of which label pitch length is short, is used, data may be written on an RFID tag next to
the target RFID tag.
As the location, where data is to be written, differs among RFID tag types, a check must be performed
to make sure that the data is written on the target RFID tags.
The B-EX RFID Analyze Tool can be used for this purpose.
12) Defective RFID Supply
RFID supplies may include defective RFID tags at the time of shipment from the maker. The defect
rate differs depending on tag types, method of converting to supplies, etc.
The RFID supply maker should provide a way to distinguish defective tags by printing a mark on them
or any other methods.
Or, defective tags should be rejected in the production process.
How to distinguish a defective tag from good one must be notified to end users.
2.4.5 Improvement of Writing Accuracy
As RFID tags use wireless technologies, writing data on the RFID tag may fail depending on
environment and characteristics of the RFID tags.
In order to improve the accuracy of writing data on the RFID tags, the following method can be used:
1) Change of the maximum number of RFID write retries
The maximum number of RFID write retries is variable and can be changed by the RFID settings in
System mode. Setting the high number can improve the writing accuracy. However, overall printing
throughput may become worse because a retry is also performed for tags on which data cannot be
written.
For details of settings, refer to the B-EX Key Operation Specification.
2) Enabling of RFID adjustment for retry
The printer has the RFID adjustment for retry feature. If writing data on the RFID tag fails, the printer
automatically feeds the RFID tag forward or backward for a specified length in order to retry writing
data.
Enabling this feature can improve the writing accuracy. However, overall printing throughput may
become worse because a retry is also performed for tags on which data cannot be written.
For details of settings, refer to the B-EX Key Operation Specification.
3) Adjustment of location of antenna
When writing data on tags, especially on short-pitch tags, the antenna may communicate with non-
target tags, and this lowers the write rate.
The B-EX4T/EX6T has a feature to pinpoint a target tag by evaluating the output power (AGC) of tags.
Setting an AGC threshold for data write enables choosing a tag of which AGC is higher than the
threshold, determining this tag to be a target tag positioned just above the antenna, and writing data on
it. This feature can prevent writing data to non-target tags (= off the antenna).
For details of settings, refer to the B-EX4T/EX6T Key Operation Specification.
NOTE: The writing control by AGC is impossible in the H1 series.
