What does 'Invalid!' mean on my Brother Label Maker?
- AAlexis HarrisSep 9, 2025
If your Brother Label Maker displays 'Invalid!', it means that an invalid number was entered as the label length, tab length, cable diameter, flag length or faceplate length. It can also mean that an invalid letter or number to be incremented was selected in the Serialize function.
