Insider Tip

To know if you should fax the paper face up or face down, look for a small logo near the feeder tray; if the paper has lines (indicating text), fax face up. If not, fax face down.

  3. Then run another telephone cable into the wall’s phone jack.
  4. Then take the telephone cord and plug it into the “Line” plug.
    • Don’t plug the cord into the “Ext” jack. There will also likely be a USB port for connecting the printer and scanner.

STEP 3 Set Up Telephone and Answering Machine (If Desired)

If there’s a telephone you would like to connect to, take another telephone cable and put it into the extension jack. Then, plug the other end of the cord into the answering machine’s “Ext” jack. Then take another telephone cord and plug it into the phone.
