Troubleshooting and support

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: You have a special ring pattern for your fax phone number (using a distinctive ring service through your telephone company), and the Distinctive Ring setting on the HP All-in- One does not match.

Solution: If you have a special ring pattern for your fax phone number (using a distinctive ring service through your telephone company), make sure that the Distinctive Ring setting on the HP All-in-One is set to match. For example, if the phone company has assigned your number a double ring pattern, make sure Double Rings is selected as the Distinctive Ring setting.

NOTE: The HP All-in-One cannot recognize some ring patterns, such as those with alternating short and long ringing patterns. If you are having problems with a ring pattern of this type, ask your phone company to assign a non-alternating ring pattern.

If you are not using a distinctive ring service, make sure that the Distinctive Ring setting on the HP All-in-One is set to All Rings.

Cause: The Distinctive Ring setting is not set to All Rings (and you are not using a distinctive ring service).

Solution: If you are not using a distinctive ring service, make sure that the Distinctive Ring setting on the HP All-in-One is set to All Rings.

Cause: The fax signal level might not be strong enough, which can cause fax reception problems.

Solution: If the HP All-in-One shares the same phone line with other types of phone equipment, such as an answering machine, a computer dial-up modem, or a multi-port switch box, the fax signal level might be reduced. The signal level can also be reduced if you use a splitter or connect extra cables to extend the length of your phone. A reduced fax signal can cause problems during fax reception.

•If you are using a splitter or extension cables, try removing them and connecting the HP All-in-One directly to the telephone wall jack.

•To find out if other equipment is causing a problem, disconnect everything except the HP All- in-One from the phone line, and then try to receive a fax. If you can receive faxes successfully without the other equipment, one or more pieces of the other equipment is causing problems; try adding them back one at a time and receiving a fax each time, until you identify which equipment is causing the problem.

Cause: The memory of the HP All-in-One is full.

Solution: If Backup Fax Reception is enabled and there is an error condition on the HP All- in-One, the memory might become full of faxes that have not yet been printed and the HP All- in-One will stop answering calls. If an error condition exists that is preventing the HP All-in-One from printing faxes, review the display for information on the error condition. Also, check for the following problems:

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

•There is no paper loaded in the input tray.

•There is a paper jam.
