FAQs & Troubleshooting

Telephone Line Interference/VoIP.

If you are having issues sending or receiving a fax due to possible interference on the telephone line or if you are using a VoIP system, we recommend changing the modem speed to minimize errors in fax operations.

 

  1. Press Settings(Settings) > All Settings > Initial Setup > Compatibility.
     
  2. Press the option you want.
     
    • Basic(for VoIP) reduces the modem speed to 9,600 bps and turns off color fax receiving(*) and Error Correction Mode (ECM), except for color fax-sending(*). Unless interference is a recurring issue on your telephone line, you may prefer use it only when needed.
      To improve compatibility with most VoIP services, Brother recommends changing the compatibility setting to Basic(for VoIP).
      *: Available only for Brother machines with color fax function
       
    • Normal sets the modem speed at 14,400 bps.
  3. Press Home(Home).
  • VoIP (Voice over IP) is a type of phone system that uses an Internet connection, rather than a traditional phone line.
  • (For some countries)
    Brother does not recommend the use of a VoIP line. VoIP limitations in general can cause some functions of the fax machine not to work correctly.
