5.11 RFID Module Setting
5-100
• Reverse feed by a Issue command or Feed command when a combination of the print speed
and the non-print area does not enable the ribbon saving function or head-up function
• Reverse feed by a U2 command on the condition that does not enable a head-up function (feed
amount = 20 mm or less).
5.11.5.4 CARRIER SENSE
The printer enters the carrier sense mode, and performs a carrier sense. Environmental radio wave
of each channel is picked up for about 30 times during 5 seconds. (This function is enabled only when
the B-EX700-RFID-U4-R is used.)
Display example
・ The left-most number indicates a channel number. The percentage means the availability of the
channel, which is determined by performing approx. 30 carrier senses. Thus, “100%” means that any
other devices do not use this channel.
・ MAX column shows the value of the maximum radio wave picked up. The larger the value is, the
stronger radio wave source exists nearby.
・ “MAX 0011” means the value of the maximum radio wave picked up.
・ The display can be scrolled up or down, from Channel 1 (1CH) to channel 9 (9CH), by using the [UP]
or [DOWN] key.
・ Pressing the [ENTER] key causes the printer to perform a carrier sense again. To quit a carrier sense,
press the [CANCEL] key.
・ When the RFID module type is set to “NONE” or a communication cannot be established, a message,
“NO RFID MODULE”, is displayed.
・ When the RFID module type is set to other than U2, a message, “NOT AVAILABLE” is displayed.
・ When the RFID module type is set to U2 but effective data cannot be obtained, a message, “NO
RESPONSE” is displayed.
・ If the RFID module’s country/region setting is not specified (user-inaccessible setting) for the B-
EX700-RFID-U2-EU/US-R, B-EX700-RFID-U4-EU/US-R or U4 module preinstall model, an “RFID
CONFIG ERR” message is displayed.
