Lexmark S800 用户手册

The printer must be connected to a telephone, DSL, VoIP, or cable service before you can configure the fax settings
in the fax software.

The Fax Solutions Software is optional for Windows users and is installed with the printer software only if you select
it on the “Install Additional Software” screen during installation. If you did not install the fax software, then the Fax
tab on the Printer Home takes you to our Web site where you can download the software.

You need to connect the printer to your telephone line through a standard wall jack (RJ-11), a DSL filter, a VoIP
adapter, or a cable modem before you can open the fax software and configure the fax settings.

The receiving fax machine cannot
receive the fax. The error on the
receiving end could be due to several
factors.

Resend the fax. There may have
been a problem with the quality of
the connection.

Decrease the transmission speed
of your fax modem.

Register your user information.
Some countries or regions require
the fax number and fax name for
you to send a fax, and some fax
machines block anonymous faxes.
Make sure to enter your fax number
and fax name correctly. This is the
information that identifies you as
the sender in all the faxes that you
send.

The receiving fax machine does not
support color fax or the scan
resolution of the document that you
are sending.

Enable Auto Fax Conversion. The
printer automatically converts
color faxes to black and lowers the
scan resolution of the document.

Lower the fax quality.

Reformat the document on letter-
or A4-size paper.

The receiving fax machine does not
support the length of the document
that you are sending.

Reformat the document on letter- or
A4-size paper.
