Why does Brother ADS-2400N show 'Registration Failed'?
- Gglenn51Sep 9, 2025
If your Brother scanner displays 'Registration Failed', it could be because the email address is too long (exceeding 64 characters) or the maximum number of email addresses in a shortcut has been reached. Ensure the email address is within the 64-character limit or delete unnecessary email addresses from the shortcut and try again.
