Faxing
A Digital Subscriber Line splits your regular telephone line into two channels: voice and Internet. Telephone and fax
signals travel through the voice channel, and Internet signals pass through the other channel. This way, you can use
the same line for analog voice calls (including faxes) and digital Internet access.
To minimize interference between the two channels and ensure a quality connection, you need to install a DSL filter
for the analog devices (fax machine, telephone, answering machine) in your network. Interference causes noise and
static on the telephone, failed and poor quality faxes for the printer, and slow Internet connection on your computer.
Note: Contact your DSL provider to obtain a DSL filter.
To install a filter for the printer:
1
Connect the line port of the DSL filter to the wall jack.
2
