Make sure it's set to Fax mode.

Press (fax icon) > (Menu icon) > Fax Setup > Receiving > Ring To Answer
Pick the number of rings you want before the fax picks up.

Save and exit.

Instructions Things You'll Need:

• Phone line
• Multi-function printer

1. Step 1 Connect the multi-function printer to a phone line. Most printers with fax capability have more than one phone jack, so make sure you are plugged into the right one.
   
2. Step 2 Turn the printer on and access the start-up menu. Pick an answering mode based on your expected usage of the fax capabilities of your machine (see the next steps for more information about this).
   
3. Step 3 Put the printer in manual mode if you expect little fax traffic. The manual mode usually requires you to pick up every call that comes to the machine. If you hear the signal for a fax, you push the start button and hang up.
   
4. Step 4 Choose the automatic mode if you expect a lot of faxes or have a dedicated fax line. In automatic mode, the printer listens to incoming calls and determines whether they are faxes or voice calls. Voice calls get sent on to your phone, and faxes are picked up by the printer.
   
5. Step 5 Select the number of rings you want your multi-function printer to give you before dropping a call. If you are using the manual mode you may want to go with four or more rings. Two rings should be sufficient in the automatic mode.
   
6. Step 6 Load paper into the paper tray. Check on the paper level frequently if you receive a lot of faxes.
   
7. Step 7 Set the desired print quality, and you are ready to receive faxes.
   

You should be all set now to receive faxes.
