What type of phone line are you using?
Dedicated line: A unique fax/phone number assigned to receive or
send faxes. The phone cord should be connected to the top port
inside the left side panel of the product (the one that is not labeled
with a telephone icon).
Shared phone line: A system where both phone calls and faxes
are received or sent using the same phone number and phone line.

time. You cannot send a fax while talking on the phone or while
connecting to the Internet using the same phone line.

patterns” on page 15
