There is probably temporary noise or static on the phone line. Try
sending the fax again. If the problem continues, call the Telephone
Company to check your phone line.
Custom Features on a Single Line
If you have Call Waiting, Caller ID, Call Waiting/Caller ID, Ring
Master, Voice Mail, an answering machine, alarm system or any other
custom feature on a single phone line with your fax machine, it may
create a problem sending or receiving fax data.
Example #1:
If you are having a telephone conversation and a fax
communication signal comes through on your Call Waiting Caller
ID feature, you can verify that the second call is a fax by switching
to it. You have the option to receive the fax call, by asking the first
caller to hang up to clear the line.
Example #2:
If you are sending or receiving a fax message while a Call Waiting
Caller ID (or other custom feature) signal comes through on the
line, the signal can temporarily interrupt or disrupt the fax data.
Brother’s ECM feature should help overcome this problem. This
condition is related to the telephone system industry, and is
common to all devices that send and receive information on a
single, shared line with custom features. If avoiding a slight
interruption is crucial to your business, a separate line with no
custom features is recommended.
