Fax doesn't recognize incoming phone call
Try this: using a cell phone, call your fax. Listen on the cell for a busy signal, fax tones, dial tone, etc. If the fax does not answer the cell, check the following: make sure the phone line is plugged into the LINE jack on the fax, NOT THE PHONE JACK. The phone jack is to connect a TELEPHONE to the fax. If problem still exists, press MENU on your MFC, and scroll to GENERAL SETUP, FAX. Scroll to SETUP RECEIVE, and, after writing down the settings, try changing the RING DELAY or RING TIME settings. If problem is still there, press CLEAR/BACK button until GENERAL SETUP appears on screen. Scroll down to INITIAL SETUP, and select RECEIVE MODE. Try changing RECEIVE MODE settings. Write them down before you change anything.
