Change the fax speed

The fax-speed setting is the modem protocol that the product uses to send faxes. It is the worldwide
standard for full-duplex modems that send and receive data across telephone lines at up to 33,600
bits per second (bps). The factory-set default for the fax-speed setting is

Fast (V.34)


You should change the setting only if you are having trouble sending a fax to or receiving a fax from a
particular device. Decreasing the fax speed might be useful when you are trying to send a fax
overseas, or receive one from overseas, or if you are using a satellite telephone connection.
