Selecting Auto or Manual Receive Mode for incoming faxes Before you select the auto or manual Receive Mode setting for incoming faxes, review the setup information in your Installation Guide to make sure your system is cabled correctly. Then make your selection based on the following. If This Is Your Situation... A separate telephone number for receiving fax calls only (no voice calls). One telephone number for both phone and fax calls, and no telephone answering machine. One telephone number for both phone and fax calls, and you do have a telephone answering machine. One telephone number for both phone and fax calls, and you subscribe to a distinctive ringing service from your telephone company. Choose this setting Auto. Manual. Auto. Auto, and click the Distinctive Ring button in the Settings box. Changing the number of rings to answer When the receive mode is set to Auto, HP OfficeJet answers the call automatically, after a specified number of rings. N To change the setting, click the arrow to the right of the Rings to Answer box to show the desired number, then click on the number. Answering machines also have a rings-to-answer feature. If you have an answering machine connected (according to scenario 3 in the Installation Guide), make sure the number of Rings to Answer in this dialog box is set to a higher number than that of your answering machine. The HP OfficeJet "listens" while the answering machine plays its greeting. If the HP OfficeJet detects fax tones, it will cut off the answering machine and receive the fax.
