Set Telephone Line Compatibility for Interference and VoIP Systems
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.
If your machine displays the All Settings menu on the Home screen, skip this step.
Option | Description |
---|---|
High | Select High to set the modem speed at 33600 bps. |
Normal | Select Normal to set the modem speed at 14400 bps. |
Basic(for VoIP) | Select Basic(for VoIP) to reduce the modem speed to 9600 bps and turn off Error Correction Mode (ECM). Unless interference is a recurring problem on your telephone line, you may prefer to use it only when needed. To improve compatibility with most VoIP services, Brother recommends changing the compatibility setting to Basic(for VoIP). |
