When iDPRT doesn't believe a label has printed correctly, it will attempt to re-print it. 

If this keeps happening, it is most likely because iDPRT hasn't learned your label's properties. This is usually followed by a blinking red light.

1) Please turn iDPRT off using the black switch behind the printer and turn it back on. This clears any pending print jobs. 

2) Ensure you have several labels available behind iDPRT and one label loaded for iDPRT to print. 

3) Please press and hold the top-circular button until you hear one beep, then let go. This starts the automatic label identification and you should see your label moving back and forth and stopping at the correct tear off point. 

4) When you a see a green light, try your print and it should print perfectly moving forward.
