RFID Printer usage steps
一、Install RFID tags and ribbons
1、Put the RFID tag into the paper bin
1）Find the
（ accessories to install the label
（2）Snap the paper roll sleeve onto the bezel
（3）The paper reel passes through the label
paper core, pay attention to the paper reel
sleeve facing inward
（4）Push in the baffle on both sides to center
the label, be careful not to be too tight
（5）Side view of paper roll installation
（6）Put the installed paper roll into the paper
compartment
（7）The label should pass through
the paper guide shaft, and the blue
paper limiter should be locked
（8）Close the print head to complete the
label installation
2、使用外置纸架
If the paper roll is too big to fit in the printer’s paper bin, you need to use an external
paper holder (optional). The installation diagram is shown in the figure above.
二、Connect the printer to the computer

三、Calibrate RFID tags
1、Run the LabelSoft software, select "Settings" -> "RFID Label Calibration" in the menu
, and open the visual label calibration tool
RFID tag calibration
read power
write power
calibration mode
Calibration completed and then query
start calibration first
The red line in the blue area means
the signal is better
The larger the signal range,
the easier the tag is to read
and write, and the narrower the
signal range, the higher the
requirement for the tag
position
If you use the printer for the first time, it is recommended to use the calibration mode:
1, read power 15, write power 20, remember to click "Change Settings" after
configuration
Restart the calibration after success
Visible fluctuations are normal signals
The height of the label plus
the spacing, the detection
height deviation is large,
which proves that the sensor
cannot detect accurately,
switch the sensor mode test
上图是比较理想的信号。

3. Cutter, please keep dialing up.
4. Paper stripper, please keep dialing up.
（1）Print RFID Labels Using Penetrating Sensors
5. Dial it down to use the penetrating sensor
Dial up to use reflective sensor;
6. For the network setting function, please keep
dialing up.
7. Use together with 8 to set the baud rate of the
serial port, please consult technical personnel for
details.
Notice:
After changing the DIP switch, the
printer needs to be turned on and off
again.
（2）Print RFID Labels Using Reflective Sensors
(3) Use the penetrating sensor to print non-RFID
ordinary labels
4. Typesetting example of LabelSoft software
1. Measure the label size
1）The ruler measures the width of the label is 44mm
2、LabelSoft software to set label size
High
Width
3、Add text, barcode and RFID objects to be printed, etc.
2）The height is 18mm
（1）Print and write RFID tag data at the same time
Write RFID data
Insert barcodes, text, RFID objects and more
what needs to be printed
（2）Read the ID of the RFID tag and convert it into a barcode and print it on
the current label
Read data from RFID tags
The read data is converted into barcode or text and printed on this label
（3）Read the ID of the RFID tag first, then write the data to the EPC and
print the surface content at the same time
read before write
5. Exception handling
1. The RFID tag calibration is abnormal
Calibration abnormalities mainly include abnormal RFID signal distribution (the
signal is too small or the signal distribution is too scattered), and the calibration
curve of the label paper is irregular. Abnormal state:
As shown below:
UHF Ultra High Frequency Tag Calibration
HF tag calibration
（1）Signal dispersion is not ideal, easy to
read and write errors
（2）The tag detection waveform is incorrect, which
will lead to abnormal calibration of the RFID signal
Solution (1):
If the situation shown in (1) appears, please try to turn the label
back and forth, and do another calibration.
RFID tags have a certain directionality. Generally, the chip is located at the back of the tag, and the signal is relatively stable,
which is conducive to the stability of reading and writing, as shown in the following figure:
If the label detection waveform shown in (2) is incorrect, that is, the label
paper calibration curve is irregular, it may be that the sensor is not selected
correctly.
The printer has two sets of label sensors (transmissive sensor and reflective sensor) built in,
which are used to locate the height and starting position of each label, RFID read and write
position, etc. If the tag positioning is abnormal, then the RFID signal calibration is also
inaccurate.
In general, flexible anti-metal tags use reflective sensors, and other RFID tags use penetrating
sensors.
Which label sensor to use is controlled by setting the dip switch on the back of the printer (refer
to the printer DIP switch description), the position of the penetrating sensor is fixed (1cm to
the left of the center), and the reflective sensor can move in the left area .
The following is a schematic diagram of the reflective sensor position of a flexible anti-metal
label:
Penetrating Sensor Position
Anti-Metal Tab Notch
The position of the reactive sensor and the position of the notch of the anti-metal
label should correspond
Reflective Sensor Position
2. Frequent errors in the printing processThe label calibration is normal, and the signal distribution is also concentrated,
but it often fails during the printing and reading process.When this happens, first check whether the consistency of the
tags is normal, that is, do 3 to 5 RFID calibrations to see if the signal distribution after each calibration is similar. If the
signal distribution after each calibration is very different, it may be that the label consistency is not good, it is
recommended to replace other labels and try again.If the signal diagrams are basically the same after each calibration, it
may be that the writing power is insufficient (the writing power is generally 3~5dBm higher than the reading power) or
the label is slipping, causing the reading and writing position to be inaccurate. Please check whether the label is fed
smoothly. Especially in the case of using an external paper holder, the labels should not be stuck too tightly, and there
should be no bends or other obstructions in the paper feeding path. In addition, reducing the printing speed can also
increase the motor torque. The default is generally 4 inches/second, and when it is adjusted to 6 inches/second, some
labels may jam or slip.
3. Calibration normal printing failed
The label calibration is normal, and the signal distribution is also concentrated, but the printing and reading fails, not
even once.
In this case, it is very likely that the format of the written data is incorrect. The EPC of the RFID tag has a capacity limit
and a limit on the number of bits to be written. For example, the EPC capacity of 96 bits can write up to 12 bytes of data.
The input fails; most chips require the minimum writing unit to be a word (2 bytes), and some chips require the minimum
writing unit to be a double word (4 bytes). It is recommended to consult the label supplier for the capacity of the chip
and the format requirements of the written data.
