2. Installing Fax Machine
Plugging in the telephone cable is not enough to render a fax machine ready for use. Various settings
are required depending on the subscriber's environment including line type, phone system (home use
or corporate use), and telephone service contract with the telephone company. You should also note
that a line that shows no problem with a telephone or PC fax/modem may not function successfully
with a fax machine. This section describes items to be checked before installing a fax machine and
how to configure the fax properly for the telephone line.
Before installing a fax machine, remove all other devices connected on the
telephone line such as PC, Voice Mail devices, etc. After the fax installation is
complete, connect them according to the User's Guide.
Some devices may not function after a fax is added on the line. For details, refer to
the User's Guide.
2.1 Items to be checked before installation
Checking the telephone line
There are three types of telephone line: touch tone dialing, pulse dialing (10PPM), and pulse dialing
(20PPM). To check the line type, confirm the setting via the fax menu and actually dial a number using
the multifunction printer's dialer or another telephone.
Check whether the line is an analog subscriber line directly connected to the PSTN (Public Switched
Telephone Network) or an extension line of an in-house phone system (so-called PBX). When, in
some cases, a fax call cannot be relayed to the public telephone network via an in-house phone line,
prepare a new analog public telephone line.
When your telephone line is part of a digital subscriber network (DSL, ISDN, etc.),
it cannot be directly connected to a fax machine (must be connected via a terminal
adapter, etc.).
When your line is one of the following, a transmission/reception error may occur.
A line connected to PC fax/modem, other fax machine, cordless telephone, credit
card terminal, and data modem (A line conflict may occur).
A line provided with a service for screening out or intercepting unwanted calls
(Voice Mail, Privacy Block, Security Screen, Anonymous Call Rejection, Privacy
Manager, etc.).
