Troubleshooting and support

Chapter 5

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.

When you have an answering machine on the same phone line you use for fax calls, you must connect the answering machine directly to the HP All-in-One using the port labeled 2-EXT, as shown below. You also need to set the correct number of rings to answer for both the answering machine and HP All-in-One.
