FAQs & Troubleshooting
Where can I find my Brother printer's serial number?
When entering your printer's serial number:
If your serial number consists of 9 characters, enter the complete number.
If your serial number consists of 15 characters, enter the last 9 characters. If there is a hyphen (-), enter the 9 characters that follow it.
Make sure you enter upper-case letters only.
The serial number (SER.NO.) is located on a label attached on the back / bottom of the printer, or inside the printer’s label roll / tape cassette compartment.
