Caller ID is not shown
Contact your telecommunications company to verify that your
telephone line is subscribed to the caller ID service.
If your region supports multiple caller ID patterns, you may have
to change the default setting. There are two settings available: FSK
(pattern 1) and DTMF (pattern 2). The availability of these settings
by way of the Fax menu depends on whether your country or
region supports multiple caller ID patterns. Contact your

EVIEW THIS DIGITAL PHONE SERVICE CHECKLIST
The fax modem is an analog device. Certain devices can be
connected to the printer so that digital telephone services can
be used.
•
If you are using an ISDN telephone service, then connect
the printer to an analog telephone port (an R-interface port)
on an ISDN terminal adapter. For more information and to
request an R-interface port, contact your ISDN provider.
• If you are using DSL, then connect to a DSL filter or router
that will support analog use. For more information, contact
your DSL provider.
• If you are using a PBX telephone service, then make sure
you are connecting to an analog connection on the PBX. If
none exists, consider installing an analog telephone line for
the fax machine.
C
HECK FOR A DIAL TONE
•
Place a test call to the telephone number to which you want
to send a fax to make sure that it is working correctly.
• If the telephone line is being used by another device, then
wait until the other device is finished before sending a fax.
• If you are using the On Hook Dial feature, then turn up the
volume to verify a dial tone.
