Parallel- vs. serial-type

phone systems

Before you begin setting up the device for faxing,

determine which kind of phone system your country/

region uses.

NOTE: The instructions for fax setup differ depending

on whether you have a serial- or parallel-type phone

system.

If you do not see your country/region listed in the

following sections, you probably have a serial-type

phone system. If you are unsure which kind of telephone

system you have (serial or parallel), check with your

telephone company.

Countries/regions with parallel-

type phone systems

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 device.

NOTE: If you have a parallel-type phone system,

HP recommends you use the 2-wire phone cord supplied

with the device to connect it to the telephone wall jack.

Countries/regions with serial-type

phone systems

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 the device. Instead,

all equipment must be connected at the telephone wall

jack.

NOTE: In some countries/regions that use serial-type

phone systems, the phone cord that came with the

device might have an additional wall plug attached to

it. This enables you to connect other telecom devices to

the wall jack where you plug in the device.
