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’ on the Transmission 
Verification Report, your machine may be out of memory. To gain extra memory, 
you can turn off Fax Storage (See 
Turning off Remote Fax Options
print fax messages in memory (See
Printing a fax from the memory
or cancel a Delayed Fax or Polling Job (See
3-8). If the problem continues, ask the telephone company to check your phone 
line.
If you frequently get transmission errors due to possible interference on the phone 
line, try changing the Compatibility setting to 
Basic
Vertical black lines when sending.
If the copy you made shows the same problem, your scanner is dirty.

Handling Incoming Calls
The machine ‘Hears’ Voice as 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 calling fax machine 
and respond with fax receiving tones. Deactivate the machine by pressing 
Stop/Exit
. Try avoiding this problem by turning Easy Receive to
Off
Sending a Fax Call to the machine.
If you answered at the machine, press
Start
and hang up immediately.
If you
answered on an external or 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, Call Waiting/Caller ID, RingMaster, Voice Mail, an 
answering machine, an alarm system or other custom feature on a single phone 
line with your machine, it may create a problem sending or receiving faxes.
For Example:
Your Brother machine handles the Caller ID subscriber services.
However, 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.
Menu Setting Difficulties
The machine beeps when you try to 
access the Setup Receive and 
Setup Send menus.
If the Fax
key is not illuminated, press it to turn on Fax mode. The Setup
Receive setting (
Menu/Set
,
2
,
1
) and Setup Send setting (
Menu/Set
,
2
,
2
) are
available only when the machine is in Fax mode.
Copy Quality Difficulties
Vertical streaks appear in copies.
Sometimes you may see vertical streaks on your copies. Either the scanner or the 
primary corona wire is dirty. Clean them both. (See 
Cleaning the laser scanner window
