Connecting the fax accessory to a phone line
When connecting the fax accessory to a phone line, ensure that the phone line being used for the fax
accessory is a dedicated line that is not used by any other devices. Also, this line should be an
analog line because the fax will not function correctly if it is connected to some digital PBX systems.
If you are not sure whether you have an analog or digital phone line, contact your telecom provider.
NOTE HP recommends using the phone cord that comes with the fax accessory to ensure
that the accessory functions correctly.
Follow these instructions to connect the fax accessory to a phone jack.
1 Locate the phone cord that is included with the fax accessory kit. Connect one end of the phone
cord into the fax accessory phone jack that is on the formatter. Push the connector until it clicks.
CAUTION Be sure to connect the phone line to the fax accessory port , which is near
the bottom of the formatter. Do not connect the phone line to the HP Jetdirect LAN port,
which is nearer the top of the formatter.
2 Connect the other end of the phone cord into the phone jack on the wall. Push the connector
until it clicks.
