Chapter 16 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. ● 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 Answer Ring Pattern feature on your HP all-in-one is set to match. For example, if the telephone company has assigned your fax number a double ring pattern, make sure Double Rings is selected as the Answer Ring Pattern setting. For information on changing this setting, see Change the answer ring pattern (distinctive ringing). 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 telephone company to assign a non-alternating ring pattern. Fax tones are recorded on my answering machine Solution ● When you have an answering machine on the same phone line you use for fax calls, try connecting the answering machine directly to the HP all-in-one as described in Fax setup. If you do not connect the answering machine as recommended, fax tones might be recorded on your answering machine. ● Make sure your HP all-in-one is set to receive faxes automatically. If your HP all-in-one is set up to receive faxes manually, 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 receive the fax and your answering machine will record the fax tones. For information on setting up your HP allin-one to receive faxes automatically, see Set up the HP all-in-one to receive faxes. ● Make sure the Rings to Answer setting is correct. The number of rings to answer for the HP all-in-one should be greater than the number of rings to answer for the answering machine. If the answering machine and the HP allin-one are set to the same number of rings to answer, both devices will answer the call, and fax tones will be recorded on the answering machine. Set your answering machine to answer in 4 rings and your HP all-in-one to answer in the maximum number of rings supported by your device. (The maximum number of rings varies by country/region.) In this setup, the answering machine will answer the call and the HP all-in-one will monitor the line. If the HP all-in-one detects fax tones, the HP all-in-one will receive the fax. If the call is a voice call, the answering machine will record the incoming message. For information on setting the number of rings to answer, see Set the number of rings before answering.
