As the gain of the tag is lower than the threshold, a data write operation is not performed for this tag at
the first try. However, the gain is greater than the lower limit.
Then the printer retires to write data to this tag according to a new AGC threshold of 10.
In this case, a retry of a data write will mostly succeed because the detected tag’s gain is greater than
the new threshold. (However, the success rate is not 100% because a gain of a tag is not always the
same.)
Example 2
AGC threshold for data write: 11
Lower limit for retry: 9
Detected tag’s gain: 8
As the gain of the tag is lower than the threshold, a data write operation is not performed for this tag at
the first try. Also, the gain is lower than the lower limit.
Then the printer retries to write data to this tag according to a new AGC threshold of 9.
In this case, a retry of data write will mostly fail because the detec
ted tag’s gain is lower than the new
threshold. (However, the error rate is not 100% because a gain of a tag is not always the same.)
When the same value is set for the AGC threshold for data write and the AGC threshold lower limit for retry,
respectively, the threshold will not be changed for a retry.
The optimum value differs depending on the tag type.
However, the problem that multiple tags are read at the same time does not occur with most RFID tag types.
It is not necessary to change the default setting of
“0”.

9.10.4.6 CALIB. MODE
This parameter is to select whether the RFID calibration function is enabled or not.
・
OFF
・
ON
Notes:
1. When enabled (ON), the AGC value (CALIB. AGC) and the distance to the read/write position (CALIB.
POSITION) obtained through an RFID calibration become effective.
2. When enabled (ON), the printer will automatically feed RFID media forward/backward for the distance
specified by CALIB. POSITION parameter before writing/reading RFID tag. Therefore, @003 command
’s
parameters
“a” and “bbbb” become invalid. (For details of the @003 command, refer to the External
Equipment Interface Specification for the B-EX Series.)
3. When the values obtained by an RFID calibration are set, this parameter will automatically turn ON.
4.
For details of the RFID calibration, refer to Section 6.7 RFID CALIBRATION.
