TROUBLESHOOTING AND ROUTINE MAINTENANCE   

14 - 9

Phone Line or Connections

The machine does not answer 
when called.

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

Basic receiving operations

 on page 5-1.) 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 there is no ringing when you 
call your machine, ask your telephone company to check the line.

Sending Faxes

Poor sending quality.

Try changing your resolution to 

Fine

 or 

S.Fine

. Make a copy to check 

your machine’s scanner operation.

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 you send a PC FAX message and get ‘Result:NG’ or, on the 
Transmission Verification Report, your machine may be out of memory. 
To gain extra memory, you can turn off Fax Storage (see 

Setting Fax 

Storage

 on page 8-3), print fax messages in memory (see 

Printing a fax 

from the memory

 on page 5-10) or cancel a Delayed Fax or Polling Job 

(See 

Canceling a scheduled job

 on page 6-11). If the problem 

continues, ask the telephone company to check your phone line.

Vertical black lines when 
sending.

If the copy you made shows the same problem, your scanner is dirty.

machine ‘Hears’ Voice as 
CNG Tone.

If your machine is set to Easy Receive 

On

, it is more sensitive to sounds. 

Your machine may mistakenly interpret certain voices or music on the 
line as a calling fax machine and respond with fax receiving tones. 
Deactivate the fax by pressing 

Stop/Exit

. Try avoiding this problem by 

turning Easy Receive to 

Off

. (See 

Easy Receive (FAX-1920CN only)

on page 5-9)

Sending a Fax Call to the 
machine.

If you answered at the machine, press 

Black

Start

 and hang up 

immediately. If you answered on an extension phone, press your Fax 
Receive Code (default setting is (

51). When your machine answers, 

hang up.

Custom features on a single 
line.

If you have Call Waiting/Caller ID with the MFC-3320CN, or Call 
Waiting, Ring Master, Voice Mail, an alarm system or any other custom 
feature on a single phone line with your machine, it may create a 
problem sending or receiving fax data.
For example: If you are sending or receiving a fax message while a 
custom feature signal comes through on the line, the signal can 
temporarily interrupt or disrupt the fax data. 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 data on a single, shared line with custom features. If avoiding a 
slight interruption is crucial to your business, we recommend a separate 
phone line with no custom features.

Printer Difficulties (MFC-3320CN only) 

Horizontal lines appear in text 
or graphics.

Clean the print head. (See 

Cleaning the print head

 on page 14-11.) If 

you clean the print heads five times and the print has not improved, call 
Brother Customer Service at 1-800-284-4329 (

in USA

), 

1-877-BROTHER (

in Canada

) or (514) 685-6464 (

in Montreal

).

Scanning Difficulties (MFC-3320CN only)

TWAIN errors appear while 
scanning.

Make sure the Brother TWAIN driver is selected as the primary source. 
In PaperPort, click Scan in the File menu and select the Brother TWAIN 
driver.
