Sending Faxes
Poor fax send quality Change your resolution to Fine or S.Fine. Make a copy to check your MFC’s
scanner operation. If the copy quality is not good, clean the scanner.
(See Cleaning the scanner glass on page 11-22.)
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 MFC may be out of memory. To gain extra memory, you
can turn off Fax Storage (See Turning off Remote Fax Options on page 6-3), print
fax messages in memory (See Printing a fax from the memory on page 4-4) or
cancel a Delayed Fax or Polling Job (See Canceling a fax in progress on page
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. (See Compatibility on page
11-20.)
Vertical black lines when sending. If the copy you made shows the same problem, your scanner is dirty.
(See Cleaning the scanner glass on page 11-22.)
Handling Incoming Calls
MFC ‘Hears’ Voice as CNG Tone. If Easy Receive is set to On, your MFC 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 MFC by pressing Stop/Exit.
Try avoiding this problem by turning Easy Receive to Off. (See Easy Receive on
page 4-3.)
Sending a Fax Call to the MFC. If you answered on an external or 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, Call Waiting/Caller ID, RingMaster, Voice Mail, an
answering machine, an alarm system or other custom feature on a single phone
line with your MFC, 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 MFC 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 MFC 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 MFC 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 scanner glass on
page 11-22 and Cleaning the drum unit on page 11-17.)
