2.5.4 Short-pitch Tag
A short-pitch tag kit is supplied with the B-SX704-RFID-U2-EU/AU-R to enable the RFID kit to encode
short-pitch tags properly. When the short-pitch tag kit is attached to the printer, the write field will be
narrower.
The RFID kit is designed so that the second label is positioned just above the antenna while the first
label is at the print start position, when using the following short-pitch label.
After printing a label, a reverse feed for a distance equivalent to one label pitch is required to write data
onto its tag. During this reverse feed, the bottom edge of the printed label may be stuck on the print
head edge, causing a feed jam. This is because the labels become thicker due to embedded tags.
When several labels are issued in a batch, set the offset printing parameter to 1 (Offset printing is
performed without a reverse feed of the first label.) in order to make the printer issue labels without
performing a reverse feed. In this case, however, the printer does not print or write data on the first
label, so it is wasteful. This mode is not suitable for applications where a small number of labels are
issued on an as-needed basis.
For details of the offset printing feature, refer to the B-SX4T/SX5T External Equipment Interface
Specification (EAA-1380).
2.5.5 Cautions for using RFID Tags
1) Lift-up of Print Head
An RFID tag chip or the thermal head may be damaged when the thermal head passes over the chip.
This can be prevented by using the ribbon saving module (standard feature for the B-SX5T and
optional for the B-SX4T) by which the thermal head is lifted up preventing it from touching the chip
when it passes over the chip.
When the thermal head is lifted up, the distance from the platen roller to the head is approximately 1
mm.
2) Storage of RFID Supplies
Do not store RFID tags close to printers, or their communication performance may not be as specified
when they are used.
