PC Fax Function (Requires the FO-LN1 Option)
Using the PC-Fax function
To fax a document from your computer, open the document in the application
used to create it and select Print from the File menu. In the Print window,
select "SHARP FO-DC Series FAX" for the printer and then click OK.
A window will appear to let you enter the destination fax number (or select it
from the address book) and select any other fax settings. When finished, click
OK. The document will be sent to the machine, which will then dial the fax
number and fax the document to the recipient.
For detailed information on using the PC-Fax function, open the Help file for
the PC-Fax driver.
