Make sure the machine is in the correct Receive Mode for your setup.
(See Receive Modes on page 47.) Check for a dial tone. If possible, call your
machine to hear it answer. If there is still no answer, check the telephone line cord
connection. If there is no ringing when you call your machine, ask your telephone
company to check the line.
Check all line cord connections. Make sure the telephone line cord is plugged into
the telephone wall socket and the LINE socket inside the machine.

There is probably temporary noise or static on the line. Try sending the fax again.
If you send a PC FAX message and get "RESULT:ERROR" on the Transmission
Verification Report, your machine may be out of memory. To gain extra memory,
you can turn off Memory Receive (See Advanced User's Guide: Turning off
Memory Receive operations.), print fax messages from the machine's memory
(See Advanced User's Guide: Printing a fax from the memory.), or cancel a
Delayed Fax or Polling Job. (See Cancelling a fax in progress on page 44.)
(See Advanced User's Guide: Checking and cancelling waiting jobs.) If the
problem continues, ask the telephone company to check your telephone line.
If you often get transmission errors due to possible interference on the telephone
line, try changing the machine's Compatibility setting to Basic(for VoIP).
(See Telephone line interference / VoIP on page 125.)
Black vertical lines on faxes you send are typically caused by dirt or correction fluid
on the glass strip. Clean the glass strip. (See Cleaning the scanner glass
on page 89.)
