When the value is “9”, the power is the weakest, and when “18”, the
power is the strongest. The factory default setting is “18”. The
optimum value differs depending on the tag types. Usually, it is not
necessary to change this value but changing the value may be able to
increase the number of successful read/write times.

In the case multiple RFID tags are read at the same time, this menu is
useful to pinpoint a target tag.
Set the Q value to “1” or greater (2 is recommended.) with the
[UP]
or
[DOWN]
key. Q value “0” causes the tags to interfere with each other
and disables proper data write.
When the Q value is set, set an AGC threshold for data write and an
AGC threshold lower limit for retry, also. Setting all these values enable
writing data to a tag placed just above the antenna.
The factory default is 0.

When the obtained gain of an RFID tag is lower than the AGC threshold,
the tag is considered as an error tag even if a data write succeeds.
When the AGC threshold is set to “0”, all tags are writable.
When set to “8”, for example, only tags with the AGC threshold level of 9
or greater are writable. The optimum value is different depending on the
tag types. The factory default is 0.
If default value fails then try it with the recommended value of 9.

When the Q value is set to 1 or greater, the AGC threshold for data write
becomes effective.
When the obtained gain of an RFID tag is lower than the AGC
thresholdfor data write, data write is not performed. In other words,
setting an AGC threshold for data write enables writing data only to a tag
placed just above the antenna.
The optimum value differs depending on the tag type.
If default value fails then try it with the recommended value of 9.

When the Q value is set to 1 or greater, the AGC threshold lower limit for
retry becomes effective.
When there are tags of which AGC values fall within the range between
the AGC threshold for data write and the lower limit, the printer retries
data write for a tag with the highest AGC value among those tags.
When printer retries data write, that value is then used as an AGC
threshold.
The optimum value differs depending on the tag type.
If default value fails then try it with the recommended value of 8.
Value should be same or 1 smaller value with Write AGC threshold
