2.5.6 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 write retries
The maximum number of write retries is variable and can be changed in the system mode. Setting
the greater value 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-SX4T/SX5T Key Operation Specification (EAA-1379).
(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
a data write.
Enabling this feature can improve the writing accuracy. However, overall printing throughput may
become worse because a retry is performed even for defective tags.
For details of settings, refer to the B-SX4T/SX5T Key Operation Specification (EAA-1379).
(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-SX4T/SX5T 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-SX4T/SX5T Key Operation Specification (EAA-1379).
