If you are having difficulty with your machineC
If you think there is a problem with the way your faxes look, make a copy first. If the copy looks 
good, the problem may not be your machine. Check the chart below and follow the troubleshooting 
tips.
Troubleshooting and routine 
maintenance

Printing or printing received faxes
DifficultiesSuggestions
„ Condensed print
„ Horizontal streaks
„ Top and bottom sentences are 
cut off
„ Missing lines Usually this is caused by a poor telephone connection. If your copy looks good, 
you probably had a bad connection, with static or interference on the telephone 
line. Ask the other party to send the fax again.
Poor print quality See  Improving the print quality on page 134.
Vertical black lines when receiving The corona wires for printing may be dirty. Clean the corona wires on the four  drum units. (See Cleaning the corona wires  on page 158.)
The sender’s scanner may be dirty. Ask the sender to make a copy to see if the 
problem is with the sending machine. Try receiving from another fax machine. 
If the problem continues, call your dealer for service .
Received faxes appear as split or 
blank pages. If the received faxes are divided and printed on two pages or if you get an extra 
blank page, your paper size setting may not be correct for the paper you are using. 
(See 
Paper Size  on page 24.) 
Turn on Auto Reduction. (See  Printing a reduced incoming fax  on page 50.)
 
						

							
126
Telephone line or connections
DifficultiesSuggestions
Dialling does not work. Check for a dial tone. (Not available in New Zealand) Change  Tone/Pulse setting. (See the  Quick 
Setup Guide .)
Check all line cord connections.
Check that the machine is plugged in and switched on.
If an external phone is connected to the machine, send a manual fax by lifting the 
handset of the external telephone and dialling the number. Wait to hear the fax 
receiving tones before pressing  Mono Start or Colour Start .
The machine does not answer 
when called. Make sure the machine is in the correct receive mode for your setup. (See 
Receive Mode settings
 on page 48.) 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.
Receiving Faxes
DifficultiesSuggestions
Cannot receive  a  fax. Check all line cord connections. Make sure the telephone line cord is plugged into  the telephone wall socket and the LINE socket of the machine. If you subscribe to 
DSL or VoIP services, please contact your service provider for connection 
instructions.
Make sure the machine is in the correct Receive Mode. This is determined by the 
external devices and telephone subscriber services you have on the same line as 
the Brother machine. (See Receive Mode settings on page 48.) 
If you have a dedicated fax line and want your Brother machine to automatically 
answer all incoming faxes, you should select  Fax Only mode.
If your Brother machine shares a line with an external answering machine, you 
should select the  External TAD mode. In External TAD  mode, your Brother 
machine will automatically receive incoming faxes and voice callers will be able to 
leave a message on your answering machine.
If your Brother machine shares a line with other telephones and you want it to 
automatically answer all incoming faxes, you should select the  Fax/Tel mode. In 
Fax/Tel  mode, your Brother machine will automatically receive faxes and 
produce a fast double-ring to alert you to answer voice calls.
If you do not want your Brother machine to automatically answer any incoming 
faxes, you should select the  Manual mode. In  Manual mode, you must answer 
every incoming call and activate the machine to receive faxes.

Cannot receive a fax.
(continued)Another device or service at your location may be answering the call before your 
Brother machine answers. To test this, lower the ring delay setting:
„ If the answer mode is set to  Fax Only or Fax/Tel , reduce the ring delay to 
1 ring. (See  Ring Delay on page 48.)
„ If the answer mode is set to  External TAD, reduce the number of rings 
programmed on your answering machine to 2.
„ If the answer mode is set to  Manual, DO NOT adjust the ring delay setting.
Have someone send you a test fax: „ If you received the test fax successfully, your machine is operating properly. 
Remember to reset your ring delay or answering machine setting back to your 
original setting. If receiving problems recur after resetting the ring delay, then 
a person, device, or subscriber service is answering the fax call before the 
machine has a chance to answer.
„ If you were not able to receive the fax, then another device or subscriber 
service may be interfering with your fax reception or there may be a problem 
with your fax line.
If you are using a telephone answering machine ( External TAD mode) on the 
same line as the Brother machine, make sure your answering machine is set up 
correctly. (See  Connecting an external TAD  on page 58.)
1 Connect the external TAD as shown in the illustration on page 59.
2 Set your answering machine to answer in one or two rings.
3 Record the outgoing message on your answering machine. „Record five seconds of silence at the beginning of your outgoing 
message.
„ Limit your speaking to 20 seconds.
„ End your outgoing message with your Remote Activation Code for people 
sending manual faxes. For example: 
“After the beep, leave a message or 
press  l51  and Start to send a fax.
”
4 Set your answering machine to answer calls.
5 Set your Brother machine
’s Receive Mode to  External TAD. (See Receive 
Mode settings  on page 48.)
Make sure your Brother machines Fax Detect feature is turned On. Fax Detect is 
a feature that allows you to receive a fax even if you have answered the call on an 
external or extension telephone. (See  Fax Detect on page 49.)
If you often get transmission errors due to possible interference on the telephone 
line, try changing the Compatibility setting to  Basic(for VoIP). (See 
Telephone line interference  on page 141.) 
(For MFC-9320CW only) Contact your administrator to check your Secure 
Function Lock Settings.

Sending faxes
DifficultiesSuggestions
Poor sending 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 glass  on page 156.)
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 75), print fax messages in memory (see  Printing a fax from the memory 
on page 51) or cancel a delayed fax or polling job (see  Checking and cancelling 
waiting jobs  on page 45). 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). (See 
Telephone line interference  on page 141.)
Sent faxes are blank. Make sure you are loading the document properly. (See  Loading documents 
on page 22)
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 156.)
Cannot send a fax. (For MFC-9320CW only) Contact your administrator to check your Secure  Function Lock Settings.
Handling incoming calls
DifficultiesSuggestions
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 49.)
Sending a Fax Call to the machine. If you answered on an external or extension telephone, press your  Remote  Activation code (default setting is l51 ( l91 for New Zealand)). 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.
