Transmission Verification Report 
says “Result:NG”
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 MFC may be out of memory. To 
gain extra memory, you can turn off Fax Storage (See page 9-2), print fax 
message in memory (See page 6-4) or cancel a delayed fax or polling job 
(See page 6-6). If the problem continues, call 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 
(See Cleaning the Scanner, page 20-16.).
Handling Incoming Calls
MFC “Hears” Voice as CNG Tone If your MFC is set to Easy Receive ON, it is more sensitive to sounds. Your 
MFC 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, page 6-3.)
Transferring a Fax Call to the MFC If you answered at the MFC, press Black Fax Start and hang up 
immediately. If you answered at an extension phone, press your Fax 
Receive Code (default setting is  51). When your MFC answers, hang up.
Custom Features on a Single Line If you have Call Waiting, Caller ID, Call Waiting/Caller ID, Ring Master, 
Voice Mail, an alarm system or any other custom feature on a single phone 
line with your MFC, 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 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.
