◦ Disconnect the answering machine and then try receiving a fax. If
faxing is successful without the answering machine, the answering
machine might be causing the problem.
◦ Reconnect the answering machine and record your outgoing message
again. Record a message that is approximately 10 seconds in
duration. Speak slowly and at a low volume when recording your
message. Leave at least 5 seconds of silence at the end of the voice
message. There should be no background noise when recording this
silent time. Try to receive a fax again.
NOTE: Some digital answering machines might not retain the
recorded silence at the end of your outgoing message. Play back
your outgoing message to check.
• If the printer shares the same phone line with other types of phone
equipment, such as an answering machine, a computer dial-up modem, or
a multi-port switch box, the fax signal level might be reduced. The signal
level can also be reduced if you use a splitter or connect extra cables to
extend the length of your phone. A reduced fax signal can cause problems
during fax reception.
To find out if other equipment is causing a problem, disconnect everything
except the printer from the phone line, and then try to receive a fax. If you
can receive faxes successfully without the other equipment, one or more
pieces of the other equipment is causing problems; try adding them back
one at a time and receiving a fax each time, until you identify which
equipment is causing the problem.
• If you have a special ring pattern for your fax phone number (using
a distinctive ring service through your telephone company), make sure that
the Distinctive Ring feature on the printer is set to match. For more
information, see Change the answer ring pattern for distinctive ring.
