4.5 Dump Mode

Note

When the label setting and the print result don't match, it is recommended to go into the Dump Mode to check for
mistakes in data transmission between the printer and the PC. Test procedures to enter the Dump Mode are as
follows:

1. Power off the printer, press and hold the FEED key.

2. Power on the printer (while still holding the FEED key) and the printer will beep 3 times.

3. Release the FEED key when LED flashes green. Printer will automatically print “DUMP MODE
BEGIN.” This means the printer is in Dump Mode.

4. Send commands to the printer, and check if the print result matches the commands sent.

5. To cancel (get out of the Dump Mode), press the FEED key, the printer will automatically print out
“OUT OF DUMP MODE”. This indicates that printer is back in the standby mode. Powering off the
printer is another way to exit the Dump Mode.

4.6 See-Through Sensor On/Off

There are two types of sensor in RL22DT/RL42DT printer - Reflective Sensor and See-through Sensor. Users
can set one of them as active sensor. By default, the Reflective Sensor is turned on and the See-throug h Sen sor is
turned off. However, the reflective sensor may not be able to detect the label gap on special label materials. For
example, when printing on labels with thick liner, colored liner, or back graphics, then the see-through sensor
would need to be enabled. To turn the See-through Sensor on:

1. Power off the printer, press and hold the FEED key.

2. Power on the printer (while still holding the FEED key) and the printer will beep 3 times. Keep holding
the FEED key, wait for the LED light turn to orange and then release the FEED key. The printers will
automatically print “SEE-THROUGH SENSOR IS ON”. This indicates that the See-Through Sensor is
turned on (and the Reflective Sensor is turned off).

3. To turn off the See-Through Sensor, please repeat above-mentioned procedures. Then the printer will
print “SEE-THROUGH SENSOR IS OFF” to indicate that the See-Through Sensor is turned off.

4. For checking the status of See-through Sensor (on or off), please perform Auto Sensing once. If LED
light is green when doing Auto Sensing, then the See-through Sensor is on. If LED light is orange, then
the See-through Sensor is off.

When the See-through Sensor is enabled, the Label Sensor must be placed in the center of the printer.
