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, 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, 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, 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. For more information on faxing when using a PBX telephone service,
see "Setting up to fax while behind a PBX" on page 79.
•
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, wait until the other device is
finished before sending a fax.
•
If you are using the On Hook Dial feature, turn up the volume to verify a dial tone.
To ensure the printer is working correctly, connect it directly to the telephone line.
Disconnect any answering machines, computers with modems, or telephone line splitters.
