Troubleshooting

B
Poor fax send quality. Try changing your resolution to Fine or S.Fine. Make a copy to check your
machine's scanner operation. If the copy quality is not good, clean the scanner.
(See Cleaning the scanner uu page 52.)
Vertical black lines when sending. 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 uu page 52.)
Handling Incoming Calls
Difficulty Suggestions
The machine “hears” a voice as a
CNG Tone. If Easy Receive 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 Easy Receive to Off.
(See Easy Receive uu page 32.)
Sending a fax call to the machine. If you answered on an extension telephone, press your Fax Receive Code (the
factory setting is l 5 1). If you answered on the external telephone (connected to
the EXT. jack), press Start to receive the fax. When your machine answers, hang
up.
Custom features on a single line. If you have Call Waiting, Call Waiting/Caller ID, Voice Mail, 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 telephone line with no
custom features is recommended.
Copying Difficulties
Difficulty Suggestions
Poor copy results when using the
ADF. Try using the scanner glass. (See Using the scanner glass uu page 22.)
Vertical black lines or streaks
appear in copies. Vertical black lines or streaks on copies are typically caused by dirt or correction
fluid on the scanner. Clean the glass strip and scanner glass and the white bar and
white plastic above them. (See Cleaning the scanner uu page 52.)
Copies are blank. Make sure you are loading the document properly. (See Loading documents
uu
page 21.)
Fit to Page does not work properly. Make sure the document is not skewed on the scanner glass.
Reposition the document and try again.
