Before you begin
The HP LaserJet 3100 product is not supported with telephone
system features provided by your local telephone company such as
the automatic answering systems often used in large companies,
voice mail, call waiting, and some other advanced features. If you are
connecting the HP LaserJet 3100 product to a line receiving both fax
and voice calls (a shared line) and have these types of features, HP
recommends getting a second telephone line dedicated to fax calls.
If you live in an area that is subject to frequent electrical storms or for
other reasons experiences numerous blackouts, it is strongly
recommended that you purchase and use a telephone line surge
protector. Electrical surges and power interruptions can damage the
HP LaserJet 3100 product.
