Suggestions
Make sure the machine is in the correct receiving mode
for your setup (either FAX, FAX/TEL, TAD). Check for
dial tone. If possible, call your machine to hear it answer.
If there is still no answer, check the telephone line cord
connection. Connect a standard telephone handset to the
machine's telephone jack. If there is no ringing when you
call your machine, call your Telephone Company to
check the line.
Press Hook —OR—Lift the handset. If you hear no dial
tone, check telephone line cord connections at the
machine and wall jack.
Check that the handset curled cord is connected to the
machine's handset jack. Test the wall jack with another
single line telephone. If no dial tone on the wall outlet,
call your Telephone Company.
(See Resolution, Page 6-5.)
Make a copy to verify the machine's scanner operation.
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.
Sometimes the resolution mode you chose when you sent
your fax may not have been appropriate. Send the fax
again, but try using the FINE or SUPERFINE mode.
Also, your machine's scanner may be dirty, so try
cleaning it. (See Page 22-16.)
Your machine's scanner may be dirty or the party
receiving party's print head may be dirty.
Clean your scanner, (see Page 22-16) and make a copy to
check if the receive problem was caused by your
machine.
The machine knows the incoming call is not a fax so it is
signaling you to answer the telephone call. Pick up the
machine's handset or answer from an extension or
external phone and then press your machine's Telephone
Answer Code (default setting is #51).
If you answered at the machine, press Fax Start and
hang up immediately. If you answered at an extension or
external phone, press your machine's Remote Activation
Code (default setting is 51). When your machine
answers, hang up.
The Caller ID signal is sent ten seconds after the Call
Waiting Signal and speaking may interfere with it. When
you hear the Call Waiting signal, ask the other party to
hold while you catch the other call. Then stop speaking
until you see the Caller ID on the LCD.
