Thank you for joining HP Forums.

It's a pleasure assisting you in finding answers to your technical queries.

To provide you with an accurate solution, I'll need a few more details:

Did you receive any fax?

How to Disable ECM on the HP 3180/3100 series fax machines.

1. Press the Fax Menu Button.
2. Press Fax Menu repeatedly to scroll through the options in the Fax Menu.
3. Press Setup the select Advanced Fax Setup and then select Error Correction Mode.
4. Press to select Off. Press OK

Change the fax speed

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.

Prepare your HP printer for faxing. These steps use a traditional landline telephone service. If you use a different type of phone service (cellular, Internet phone, PBX, or DSL), see the FAQs in this document to set up the connection.

1. Obtain a telephone cord. Use the cord that came with the printer. If you do not have the original cord, use a cord with connectors that have two wire leads, not four.

   

2. Connect the phone cord to the phone wall jack and to the 1-LINE jack on the back of the printer.

   

3. If you have an answering machine, connect a phone cord to the machine and to the 2-EXT jack on the rear of the printer. Doing so allows your telephone answering machine to record voice calls normally without recording the noises from faxes.

   1. Wall jack

   2. Two-wire phone cord

   3. Answering machine

   4. Single-line telephone

4. Set up fax settings and preferences. The HP software includes guided fax setup tools (the Fax Setup Wizard in Windows or the Basic Fax Settings tool for Mac), or navigate to the Fax or Setup menus on the printer control panel.

   • Fax header: Enter the text you want recipients to see at the top of your faxes. A typical fax header contains your name, the name of your business, and the complete 10-digit fax telephone number.

   • Answer mode/Auto answer: Picks up your phone calls after a specified number of rings and accepts incoming faxes. If this feature is off, a person must manually accept incoming faxes from the printer control panel.

   • Rings to answer: When the phone rings, the printer waits and counts the number of telephone rings before it answers the call.

     • If the phone line is shared with your voice calls, choose a number of rings that provides enough time for you to answer the phone before the printer picks up a call.

     • If the phone line is shared with an answering machine, choose a number to pick up that is two rings more than the answering machine. Doing so ensures the answering machine answers the phone before the printer.

   • Set the ring type: Use the All Rings setting for a dedicated fax line or select Distinctive Ring if you set up a special ring pattern for the fax line.

   • Dial type: Match the type of analog phone service you have; tone or pulse. If the dial type does not match, the printer cannot detect rings and answer incoming calls.

     The current industry standard is tone dial in most areas. You might have pulse dialing if you use a rotary telephone. If you are not sure of the dial type, contact your phone service provider.

   • Fax volume: Select a volume level to hear sounds made during the fax call, such as dial tones and busy signals. Set the volume to Off if you want silent faxing.

5. Run a fax test to confirm the fax set up was successful. On the printer control panel, locate Run Fax Test or Fax Test Report in the Fax or Setup menus. A report prints with test results and any instructions to resolve issues.

   Additionally, you can test send and receive functionality with the HP Fax Test Service. Send a fax to 1-888-HPFaxme (1-888-473-2963 U.S.). The service receives faxes and returns faxes within 5 to 7 minutes to the fax number contained in the fax header.
