Lexmark X5470 User Guide

CAUTION—SHOCK HAZARD: Do not use the fax feature during a lightning storm. Do not set up this product
or make any electrical or cabling connections, such as the power supply cord or telephone, during a lightning
storm.

You can connect the printer with equipment such as a telephone, an answering machine, or a computer modem. If
problems occur, see “Setup troubleshooting” on page 135.

Note: The printer is an analog device that works best when directly connected to the wall jack. Other devices (such
as a telephone or answering machine) can be successfully attached to pass through the printer, as described in the
setup steps. If you want a digital connection such as ISDN, DSL, or ADSL, a third-party device (such as a DSL filter) is
required.

You do not need to attach the printer to a computer, but you do need to connect it to a telephone line to send and
receive faxes.

You can connect the printer to other equipment. See the following table to determine the best way to set up the
printer.
