The printer retries to write data onto an RFID tag for up to the specified number of times. If the data write
period expired before the specified number of retries, the printer stops the retries at the time.
(2) The timeout for RFID tag write retry
Max.

value
9.9
0.0
The printer retries to write data on an RFID tag for the specified length of time.
If the printer has retried for the specified number of times within the RFID write retry timeout, the printer

In the case multiple RFID tags are read at the same time, this menu is useful to focus on a target tag. Set the
Q value to "1" or above (2 is recommended). 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 enables writing data to a tag placed just above the antenna.
Actually, the problem of reading multiple tags at the same time does not occur with most RFID tag types. It is
