Sending Faxes
Difficulty Suggestions
Cannot send a fax Check all line cord connections.
Make sure that the Fax key is illuminated. (See Entering Fax
mode on page 22.)
Ask the other party to check that the receiving machine has paper.
Print the Transmission Verification Report and check for an error. (See
Reports on page 58.)
Make sure the panel cover is completely closed.
Transmission Verification Report
says ‘Result:NG’ or
‘Result:ERROR’.
There is probably temporary noise or static on the line. Try sending the fax again.
If the problem continues, ask the telephone company to check your phone line.
If you often get transmission errors due to possible interference on the phone line,
try changing the menu setting of Compatibility to Basic. (See Phone line
interference on page 86.)
If you connect your machine to PBX or ISDN, set the Phone Line Type in the menu
settings. (See Setting the Phone Line Type on page 37.)
Poor fax send quality. Try changing your resolution to Fine or S.Fine. Make a copy to check your
machine's scanner operation. If the copy quality is not good, clean the scanner.
(See Cleaning the scanner on page 89.)
Vertical black lines when sending. If the copy you made shows the same problem, clean the scanner. (See Cleaning
the scanner on page 89.)
Handling Incoming Calls
Difficulty Suggestions
The machine ‘Hears’ a voice as a
CNG Tone.
If Fax Detect is set to on, your machine is more sensitive to sounds. It may
mistakenly interpret certain voices or music on the line as a fax machine calling
and respond with fax receiving tones. Deactivate the machine by pressing
Stop/Exit. Try avoiding this problem by turning Fax Detect to off. (See Fax
Detect on page 31.)
Sending a fax call to the machine. If you answered at the machine, press Start and hang up at once. If you answered
on an external or extension phone, press your Fax Receive Code (default setting
is l51). When your machine answers, hang up.
Custom features on a single line. If you have Call Waiting, Call Waiting/Caller ID, an alarm system or other custom
feature on a single phone line with your machine, it may create a problem sending
or receiving faxes.
For example:
If you subscribe to Call Waiting or some other custom service and
its signal comes through the line while your machine is sending or receiving a fax,
the signal can temporarily interrupt or disrupt the faxes. 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 phone line with no custom features is recommended.
Menu Setting Difficulty
Difficulty Suggestions
The machine beeps when you try to
access the Setup Receive menu. If the Fax key is not illuminated, press it to turn on Fax mode. The Setup
Receive setting is available only when the machine is in Fax mode.
