The HP All-in-One cannot receive faxes, but can send faxes

Cause The HP All-in-One is not set up properly for faxing.

Solution Follow the instructions in this guide to set up the HP All-in-One properly for faxing, based on the equipment and services you have on the same phone line as the HP All-in-One. Then, run a fax test to check the status of the HP All-in-One and to make sure you set it up properly.

The HP All-in-One prints a report with the results of the test. If the test fails, review the report for information on how to fix the problem.

Cause Auto Answer is turned off, which means that the HP All-in-One will not answer incoming calls. You must be available to respond in person to incoming fax calls, or the HP All- in-One will not answer the incoming fax call.

Solution Depending on your office setup, you might be able to set the HP All-in-One to answer incoming calls automatically.

If you must have Auto Answer off, you will need to press Start Fax Black or Start Fax Color to receive a fax.

Tip If you are not close enough to the HP All-in-One to reach the control panel, wait several seconds, and then press 1 2 3 on your phone. If the HP All-in-One does not begin receiving the fax, wait several more seconds and press 1 2 3 again. After the HP All-in-One begins to receive the fax, you can hang up the phone.

Cause You subscribe to a voice mail service at the same phone number you use for fax calls. Solution Set the HP All-in-One to answer faxes manually. You cannot receive faxes automatically if you have a voice mail service at the same phone number you use for fax calls. You must receive faxes manually; this means you must be available to respond in person to incoming fax calls.

Cause You have a computer dial-up modem on the same phone line as the HP All-in-One. Solution If you have a computer dial-up modem on the same phone line as the HP All-in- One, check to make sure that the software that came with your modem is not set to receive faxes automatically. Modems that are set up to receive faxes automatically take over the phone line to receive all incoming faxes, which prevents the HP All-in-One from receiving fax calls.

Cause If you have an answering machine on the same phone line with the HP All-in-One, you might have one of the following problems:

Your outgoing message might be too long or too loud to allow the HP All-in-One to detect fax tones, and the sending fax machine might disconnect.

Your answering machine might not have enough quiet time after your outgoing message to allow the HP All-in-One to detect fax tones. This problem is most common with digital answering machines.

Solution If you have an answering machine on the same phone line with the HP All-in-One, do the following:

Disconnect the answering machine and then try receiving a fax. If faxing is successful without the answering machine, the answering machine might be causing the problem.

Reconnect the answering machine and record your outgoing message again. Record a message that is approximately 10 seconds in duration. Speak slowly and at a low volume when recording your message. Leave at least 5 seconds of silence at the end of the voice message. There should be no background noise when recording this silent time. Try to receive a fax again.

Cause The answering machine is not set up properly with the HP All-in-One.
