Set up the HP All-in-One for faxing
Before you begin setting up your HP All-in-One for faxing, determine which kind of
phone system your country/region uses. The instructions for setting up your HP All-in-
One for faxing differ depending on whether you have a serial- or parallel-type phone
If you do not see your country/region listed in the table below, you probably have
a serial-type phone system. In a serial-type phone system, the connector type on
your shared telephone equipment (modems, phones, and answering machines)
does not allow a physical connection to the "2-EXT" port on your HP All-in-One.
Instead, all equipment must be connected at the telephone wall jack.
If your country/region is listed in the table below, you probably have a parallel-
type telephone system. In a parallel-type phone system, you are able to connect
shared telephone equipment to the phone line by using the "2-EXT" port on the
back of the HP All-in-One.
If you have a parallel-type phone system, HP recommends you use
the 2-wire phone cord supplied with your HP All-in-One to connect the
HP All-in-One to the telephone wall jack.
Countries/regions with a parallel-type phone system
If you are unsure which kind of telephone system you have (serial or parallel), check
with your telephone company.
