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 34.)
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 84.)
Transmission Verification Report
says ‘Result:NG’.
There is probably temporary noise or static on the line. Try sending the fax again.
If you send a PC FAX message and get ‘Result:NG’ on the Transmission
Verification Report, your machine may be out of memory. To gain extra memory,
you can turn off Advanced Fax Operation (see Turning off Advanced Fax
Operations on page 79), print fax messages in memory (see Printing a fax from
the memory on page 46) or cancel a Delayed Fax or Polling Job (see Canceling a
fax in progress on page 35). If the problem continues, ask the telephone company
to check your telephone line.
If you often get transmission errors due to possible interference on the telephone
line, try changing the menu setting of Compatibility to Basic. (See Telephone line
interference on page 146.)
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 149.)
Vertical black lines when sending. Black vertical lines on faxes you send are typically caused by dirt or correction
fluid on the glass strip. Clean the glass strip. (See Cleaning the scanner
on page 149.)

Handling Incoming Calls

Difficulty Suggestions
The machine ‘Hears’ a voice as a
CNG Tone.
If Easy Receive 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 Easy Receive to off. (See Easy
Receive on page 45.)
Sending a fax call to the machine. If you answered on an external or extension telephone, press your Fax Receive
Code (the factory setting is l 5 1). When your machine answers, hang up.
Custom features on a single line. If you have Call Waiting, Call Waiting/Caller ID, Voice Mail, an alarm system or
other custom feature on a single telephone 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 telephone line with no custom features is
recommended.
