Suggestions
There is probably temporary noise or static on the line. Try sending the fax again.
If you send a PC FAX message and see RESULT:ERROR on the Transmission
Verification Report, your machine may be out of memory. To gain extra memory,
you can print fax messages from the machine's memory. (See Advanced User's
Guide: Printing a fax from the memory.) If the problem continues, ask the
telephone company to check your telephone line.
If you often get transmission errors due to possible interference on the telephone
line, try changing the machine's Compatibility setting to Basic(for VoIP).
(See Telephone line interference / VoIP on page 92.)
If you connect your machine to PBX or ISDN, set the menu setting of Telephone
Line Type to your telephone line type. (See Setting the Telephone Line Type
on page 33.)
Black vertical lines on faxes you send are typically caused by dirt or correction fluid
on the glass strip. Clean the glass strip. (See Cleaning the scanner glass
on page 58.)
Suggestions
If Fax Detect is set to On, your machine is more sensitive to sounds. It may
mistakenly interpret certain voices or music on the line as a fax machine calling
and respond with fax-receiving tones. Deactivate the machine by pressing
Stop/Exit. Try avoiding this problem by turning Fax Detect to Off.
(See Fax Detect on page 31.)
If you answered on an extension or external telephone, press your Remote
Activation Code (the factory default is l 5 1). If you answered on an external
telephone, press Mono Start or Colour Start, and press 2 to receive the fax.
When your machine answers, hang up.
If you have Call Waiting, Call Waiting/Caller ID, Caller ID, Voice Mail, an
answering machine, an alarm system or other custom feature on a single
telephone line with your machine, it may create a problem sending or receiving
faxes.
For example: If you subscribe to Call Waiting or another custom service and its
signal comes through the line while your machine is sending or receiving a fax, the
signal can temporarily interrupt the faxes. Brother's ECM (Error Correction Mode)
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, we recommend using a separate
telephone line with no custom features.
Suggestions
Black vertical lines on copies are typically caused by dirt or correction fluid on the
glass strip. Clean the glass strip, scanner glass, white bar and white plastic above
them. (See Cleaning the scanner glass on page 58.)
Try using the scanner glass. (See Using the scanner glass on page 22.)
Reposition the document and try again.
