IfYou Are Having Difficulty withYour MFC

If you think there is a problem with your MFC, make a copy first. If the copy looks good, the problem is probably not your MFC. Check the chart below and follow the troubleshooting tips.

Streaks / Top and Bottom of		static or interference on the phone line.
Sentences Are Cut Off		If a copy looks worse, then call your Brother dealer for service.
Vertical streaks/black lines appear on		Sometimes you may see vertical streaks/black lines on the faxes you
the fax you receive		receive. Either your machine’s primary corona wire for printing may
		be dirty, or the sending party’s fax scanner may be dirty. Clean your
		primary corona wire, or 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 Brother dealer for service.
Phone Line or Connections
MFC Does Not Answer When Called		Check for dial tone. If possible, call your MFC 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 MFC, call your Telephone
		Company to check the line.
Sending Faxes
Poor Transmitting Quality		Try changing your resolution to FINE or S.FINE. Make a copy to
		verify your MFC’s scanner operation.
Transmission Verification Report says		There is probably temporary noise or static on the line. Try sending the
“Result:NG” again.		fax 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 in this chapter).
Handling Incoming Calls
Transferring a Fax Call to the MFC		If you answered at an extension phone, press your Remote Activation.
Code (default setting is	51).	When your MFC answers, hang up.
Custom Features on a Single Line		If you have Voice Mail, an answering machine, alarm system or any
		other 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.
