Problem Cause Solution
Incoming fax calls are not
being answered by the device. The answer mode might be set
to Manual. If the answer mode is set to
Manual, the device does not
answer calls. You have to start
the fax-receiving process
manually. See
Setting the
answer mode for more
information.
The rings-to-answer setting
might not be set correctly. Check the rings-to-answer
setting for your configuration.
See
Changing the rings-to-
answer setting to determine
which setting you need.
The answer-ring pattern feature
might be turned on, but you do
not have the service, or you do
have the service and the
feature is not set correctly. Check the answer-ring pattern
feature to verify that it is set
properly. See
Changing ring
patterns for call answering .
The fax cord might not be
correctly connected, or the fax
cord is not working. See the Getting Started Guide
to check the installation. Verify
that you are using the fax cord
that came with the device.
The device might not be able to
detect incoming fax tones
because the answering
machine is playing a voice
message. Re-record your answering
machine message, leaving at
least two seconds of silence at
the beginning of the message.
Too many devices might be
connected to the telephone line. You should not have more than
three devices attached to the
line. Try removing the last
device that was connected and
determine whether the device
works. If not, continue
removing devices one at a time
and retry after removing each
one.

working. Do one of the following:
● Increase the volume on
the device, and then press
S

on the control
panel. If you hear a dial
tone, the telephone line is
working.
● Disconnect the device
from the telephone jack,
and then connect a
telephone. Try to make a
telephone call to verify that
the telephone line is
working.
