There may be temporary noise or static on the line. Try sending the fax again. If
you are sending a PC-FAX message and get RESULT:ERROR on the Transmission
Verification Report, your machine may be out of memory. To free up extra
memory, you can turn off fax storage (see Advanced User's Guide), print fax
messages in memory (see Advanced User's Guide) or cancel a delayed fax
(see Advanced User's Guide). 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 Compatibility setting to Basic(for VoIP) (see Telephone
line interference / VoIP on page 150).
Make sure you are loading the document correctly. When using the ADF, the
document should be face up. When using the scanner glass, the document should
be face down (see Loading documents on page 37).
Black vertical lines on faxes you send are typically caused by dirt or correction fluid
on the glass strip (see Cleaning the scanner glass on page 101).
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
Try avoiding this problem by turning Fax Detect to Off (see Fax Detect
on page 45).
Activation Code (default setting is l51).
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 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 (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, a separate line with no custom
features is recommended.
Suggestions
Make sure you pressed Copy and the machine is in Copy mode (see How to copy
on page 59).
Contact your administrator to check your Secure Function Lock Settings.
Black vertical lines on copies are typically caused by dirt or correction fluid on the
scanner glass, or the corona wires are dirty. Clean the glass strip and scanner
glass and also the white bar and white plastic above them (see Cleaning the
scanner glass on page 101 and Cleaning the corona wires on page 106).
