To set up the HP All-in-One to a computer with one phone port

1.Find the phone cord that connects from the back of your computer (your computer dial-up modem) to a telephone wall jack. Disconnect the cord from the telephone wall jack and plug it into the port labeled 2-EXT on the back of the HP All-in-One.

2.Using the phone cord supplied in the box with the HP All-in-One, connect one end to your telephone wall jack, then connect the other end to the port labeled 1-LINE on the back of the HP All-in-One.

NOTE: If you do not use the supplied cord to connect from the telephone wall jack to the HP All-in-One, you might not be able to fax successfully. This special phone cord is different from the phone cords you might already have in your home or office.

3.Remove the white plug from the port labeled 2-EXT on the back of the HP All-in- One.

4.Using another phone cord, connect one end to the port labeled 2-EXT on the back of the HP All-in-One. Connect the other end of the phone cord to the parallel splitter on the side with the single phone port.

5.Unplug your computer modem from the telephone wall jack, and connect it to the parallel splitter on the side with two phone ports.

6.If your modem software is set to receive faxes to your computer automatically, turn off that setting.

NOTE: If you do not turn off the automatic fax reception setting in your modem software, the HP All-in-One will not be able to receive faxes.

7.(Optional) Connect a phone to the other open phone port on the parallel splitter.

8.Now you need to decide how you want the HP All-in-One to answer calls, automatically or manually:

•If you set up the HP All-in-One to answer calls automatically, it answers all incoming calls and receives faxes. The HP All-in-One will not be able to distinguish between fax and voice calls in this case; if you suspect the call is a voice call, you will need to answer it before the HP All-in-One answers the call. To set up the HP All-in-One to answer calls automatically, turn on the Auto Answer setting.

•If you set up the HP All-in-One to answer faxes manually, you must be available to respond in person to incoming fax calls or the HP All-in-One cannot receive faxes. To set up the HP All-in-One to answer calls manually, turn off the Auto Answer setting.

9.Run a fax test.

If you pick up the phone before the HP All-in-One answers the call and hear fax tones from a sending fax machine, you will need to answer the fax call manually.

Cause: I am setting up the HP All-in-One on a shared voice/fax line with a computer dial-up modem and answering machine, and the computer only has one phone port.

Solution: If your computer has only one phone port, you will need to purchase a parallel splitter (also called a coupler). (A parallel splitter has one RJ-11 port on the front and two RJ-11 ports on the back. Do not use a 2-line phone splitter, a serial
