„Condensed print
„Horizontal streaks
„Top and bottom sentences are 
cut off
„Missing linesUsually 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 120.
Vertical black lines when receiving The corona wire for printing may be dirty. Clean the corona wire. (See Cleaning 
the corona wire on page 145.)
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 23.) 
Turn on Auto Reduction. (See Printing a reduced incoming fax on page 51.)
Telephone line or connections
DifficultiesSuggestions
Dialling does not work. Check for a dial tone.
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 Start.
Key operations do not work. Check the control panel is fitted correctly on the machine. Reinstall the control 
panel.

The machine does not answer 
when called.Make sure the machine is in the correct receive mode for your setup. (See 
Receiving a fax on page 47.) 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 jack and the LINE jack 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 49.) 
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 pseudo/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.
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 49.)
„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.

Sending faxesC
Cannot receive a fax.
(continued)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 54.)
1 Connect the external TAD as shown in the illustration on page 55.
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 Fax Receive 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 49.)
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 50.)
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 127.) 
(MFC-8380DN) Contact your administrator to check your Secure Function Lock 
Settings.
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 on page 143.)
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 67), print fax messages in memory (See Out of Paper Reception 
on page 52) 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 127.)
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 on page 143.)
The machine does not scan all the 
pages of your document.Make sure that the ADF output tray does not contain more than 20 sheets.

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 50.)
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). 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.
DifficultiesSuggestions
The machine beeps when you try to 
access the Setup Receive and 
Setup Send menus.If Fax   is not illuminated, press it to turn on Fax mode. The Setup Receive 
setting (Menu, 2, 1) and Setup Send setting (Menu, 2, 2) are available only when 
the machine is in Fax mode.
DifficultiesSuggestions
Cannot make a copy
„Make sure that Copy   is illuminated. (See Entering copy mode 
on page 78)
„Contact your administrator to check your Secure Function Lock settings.
Vertical black line appears in 
copies.Black vertical lines on copies are typically caused by dirt or correction fluid on the 
glass strip, or the corona wire for printing is dirty. (See Cleaning the scanner 
on page 143 and Cleaning the corona wire on page 145.)
The machine does not scan all the 
pages of your document.Make sure that the ADF output tray does not contain more than 20 sheets.
