Sending Faxes
Poor Transmitting Quality
Try changing your resolution to FINE or SUPERFINE (see “Resolution”
p. 34). Make a copy to verify the fax machine’s scanner operation.
Dialing Does Not Work
Check all line cord connections, and make sure the curled handset cord
is not in the EXT jack.
Check power cord connection.
Send a manual fax by pressing Hook —OR—Lifting the handset, and
dialing the number. Wait to hear fax receiving tones before pressing
Start .
Vertical Black Lines When Sending
Use your fax machine to make a copy. If the copy shows the same
problem, the scanner area is dirty. Lift the front cover and check the
document path. Clean the scanner’s white tape and the glass strip under
the tape using isopropyl alcohol and a lint-free cloth (see p. 59).
Handling Incoming Calls
Double Ring in FAX/TEL Mode
The fax machine knows the incoming call is not a fax so it is signaling
you to answer the telephone call. Pick up the fax machine handset or
answer from an extension phone and press your fax machine’s
Telephone Answer Code (default setting is #51).
Transferring a Call to the Fax Machine
If you have answered the fax machine handset, press Start , and hang up
immediately.
If you answered at an extension phone, press your three-digit Fax
Receive Code (the factory setting is 51). When your fax machine
answers, hang up.
Fax Machine “Hears” Voice as CNG Tone
If your fax machine is set to Easy Receive ON, and it answers voice
calls by trying to receive a fax, try turning Easy Receive to OFF.
