3-1. FEED button
When you press the FEED button, the printer moves the label to the defined stop position. If you
are using continuous labels, pressing the FEED button will move label stock until you release the
button again. If you are using individual labels, pressing the FEED button will move only one
label. If the label does not stop at the correct position, you need to run the auto-detection function
on the label stock (see Section 3-3).
3-2. LED status
*Note: This description applies only to firmware versions G3.000 or higher.
Press the FEED button and keep it pressed, then switch on the printer. You will hear two beeps
and the LED lights up red. Release the FEED button. The printer will now automatically measure
the label size (see Section 4-3.) and then print a test page (see Section 4-4.)
LED

Green Standby mode The printer is ready for operation.
Red
(flashing) Error mode The printer has detected an error. (see Section 3-5. Error alerts)
3-3. Label size calibration
The printer can automatically detect and store label height.
That means the host computer does not need to transmit the label height to the printer.
1. Check that the label sensor is positioned correctly.
2. Check that the label stock is loaded correctly.
3. Switch off the printer.
4. Switch on the printer, keeping the FEED button pressed. When the LED starts to flash red,
release the FEED button. The printer will now measure the label stock and store the label
height.
5. Once the printer has successfully measured the label stock, it will print a self-test label.
