The machine does not answer
when called.

Make sure the machine is in the correct receive mode for your setup. (See

on page 39.) Check for a dial tone. If possible, call your machine

to hear it answer. If there is still no answer, check the telephone line cord
connection. If you do not hear ringing when you call your machine, ask your
telephone company to check the line.

Sending faxes

Difficulties

Suggestions

Poor sending quality.

Try changing your resolution to

Fine

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 glass

on page 115.)

Transmission Verification Report
says ‘RESULT:ERROR’.

There is probably temporary noise or static on the line. Try sending the fax again.
If you are sending a PC Fax message and get ‘RESULT:ERROR’ on the
Transmission Verification Report, your machine may be out of memory. To free up
extra memory, you can turn off fax storage (see

Turning off remote fax options

on page 58), print fax messages in memory (see

Printing a fax from the memory

on page 43) or cancel a delayed fax or polling job (see

Checking and cancelling

waiting jobs

on page 38). 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 Compatibility setting to

Basic(for VoIP)

(For

MFC-7840W,

Normal

Basic(for VoIP)

). (See

Telephone line interference

on page 102.)

Vertical black lines when sending.

Black vertical lines on faxes you send are typically caused by dirt or correction fluid
on the glass strip. (See

Cleaning the scanner glass

on page 115.)

Handling incoming calls

Difficulties

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 41.)

Sending a Fax Call to the machine. If you answered on an external or extension telephone, press your Remote

Activation code [default setting is (

51)]. When your machine answers, hang up.

Custom features on a single line.

If you have Call Waiting, Call Waiting/Caller ID, Caller ID, Voice Mail, an
answering machine, 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 line with no custom features is recommended.
