Suggestions
Make sure you are loading the document correctly. (See Loading documents
on page 18.)
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 on page 55.)
Suggestions
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
Detener/Salir (Stop/Exit). Try avoiding this problem by turning Easy Receive to
Off.
(See Easy Receive on page 28.)
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 Inicio Negro (Black 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, RingMaster, 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 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, we recommend using a separate
telephone line with no custom features.
