HP LaserJet Pro 300 Color MFP M375 - Manual (Page 228)

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.
1. From the Home screen, touch the Setup button.
2. Touch the Fax Setup menu.
3. Touch the Advanced Setup menu.
4. Scroll to and touch the Fax Speed button, and then touch the speed setting that you want to use.
