Send a fax manually from a phone You can send a fax from a telephone on the same phone line if you prefer to use the keypad on your phone, instead of the keypad on the control panel of the device. You can do this by plugging in a phone into the 2-EXT port on the back of the device. When you send a fax manually, you can hear the dial tones, telephone prompts, or other sounds through the handset on your telephone. This makes it easy for you to use a calling card to send your fax. Depending on how the recipient has their fax machine set up, the recipient might answer the phone, or the fax machine might take the call. If a person answers the phone, you can speak with the recipient before sending the fax. If a fax machine answers the call, you can send the fax directly to the fax machine when you hear the fax tones from the receiving fax machine.
1. Load your originals. NOTE: This feature is not supported if you load your originals on the glass. You must load your originals in the document feeder tray. 2. Dial the number by using the keypad on the phone that is connected to the device. NOTE: Do not use the keypad on the control panel of the device when manually sending a fax. You must use the keypad on your phone to dial the recipient's number. 3. If the recipient answers the telephone, you can engage in a conversation before sending your fax. NOTE: If a fax machine answers the call, you will hear fax tones from the receiving fax machine. Proceed to the next step to transmit the fax. 4. When you are ready to send the fax, press START FAX Black or START FAX Color. NOTE: If prompted, select Send Fax, and then press START FAX Black or START FAX Color again. If you were speaking with the recipient before sending the fax, inform the recipient that they should press Start on their fax machine after they hear fax tones.
The telephone line is silent while the fax is transmitting. At this point, you can hang up the telephone. If you want to continue speaking with the recipient, remain on the line until the fax transmission is complete.

Send a fax using monitor dialing Monitor dialing allows you to dial a number from the control panel as you would dial a regular telephone. When you send a fax using monitor dialing, you can hear the dial tones, telephone prompts, or other sounds through the speakers on the device. This enables you to respond to prompts while dialing, as well as control the pace of your dialing. TIP: If you do not enter your calling card PIN fast enough, the device might start sending fax tones too soon and cause your PIN not to be recognized by the calling card service. If this is the case, you can create a speed dial entry to store the PIN for your calling card. NOTE: Make sure the volume is turned on, or you will not hear a dial tone. To send a fax using monitor dialing from the control panel
1. Load your originals. NOTE: If you are sending a multiple-page fax, you must load the originals print-side up in the document feeder tray. You cannot fax a multiple-page document from the glass. 2. Press START FAX Black or START FAX Color. • If the device detects an original loaded in the automatic document feeder, you will hear a dial tone. • If the device does not detect an original loaded in the automatic document feeder, the Fax from glass? prompt appears. Make sure that your original is loaded on the glass, and then select Yes. 3. When you hear the dial tone, enter the number by using the keypad on the control panel. 4. Follow any prompts that might occur. TIP: If you are using a calling card to send a fax and you have your calling card PIN stored as a speed dial, when prompted to enter your PIN, press Speed Dial or a one-touch speed dial button to select the speed dial entry where you have your PIN stored.
