Red Light is Flashing
The red light is an indication that the Prafia printer has a problem with your label.
Performing the Automatic Label Identification can resolve the issue.
Most likely, the Prafia printer needs to re-learn your label.
Please ensure there are multiple labels available to the Prafia printer and then run the automatic label identification. Simply press and hold the top circular button on the Prafia printer. For the Prafia Flex, release it when you hear one beep. For the Prafia Pro, release it after the blue light flashes twice. Prafia will then move the labels back and forth to learn the gap and other label properties.

If the automatic label identification does not work or the red light remains, please turn off the Prafia printer using the power switch on the back and then turn the unit back on.
